Modifying Logitech C920 for CS lenses

2013-07-15 21:12 | Categories: In English, Projektai, Užrašai

IMG_5658_tLogitech C920 is a wonderful webcam. It produces good picture quality and has hardware H.264 encoder. It can do real full HD streaming (1920×1080 p @ 30fps). But this webcam lacks one feature – it has fixed lens which sometimes is not acceptable. Also by removing stock lens you have access to infrared (IR) part of spectrum. There comes custom black anodized aluminium case.

 

 

 

This case can be purchased on Kurokesu e-shop

 

2014-09 update

 

Good news! I have received even more professionally manufactured C920 cases.

 To minimize confusion I did not created new post, but updated old one instead. Since today I have several high quality black anodized casings in my hands. I share some pictures and assembly guides with you.

Original post

 

I vandalized plastic case, removed electronics and build my own version of it. Here comes improved aluminium housing, which is much more comfortable to use with most scientific applications.

    Fantastic! I would love to have one of these cases. Do you plan to make the plans available or to sell copies?

      Would you be willing to pay ~50USD? I could order small batch (10pcs. or more) if there were more interested people. Of course there would be detailed instructions how to make C920 modifications.

    What lens did you put on it?

    • Saulius Lukšė
      2013-09-24 07:14

      It’s a 2.8mm 1/3″ cheap lens.

  4. Len
    2013-09-24 16:24

    So, you took off the CArl Zeiss lens? If so, why?

  5. Saulius Lukšė
    2013-09-24 21:59

    Len, I can use not only cheap ones (like in this photo), but any C or CS lens. Which means telescopes, super wide, infrared or any other lens you might think of.

  6. Syreeta
    2013-10-24 01:11

    This looks promising…

    Do you know if the PCB can be modified at all to make it smaller? Also, which do you think would give the best quality FULL resolution image; the C910 or the C920. I’d like to buy one for stop motion animation, but I can’t decide. I was going to buy a C910 and modify it to accept a M12 lens mount, but if C or CS lenses are better, then I might change my mind. The deciding factor is how good the quality of image is and since the C910 has a 5 MP sensor instead of the 3 MP sensor, the C920 has, I keep thinking I’ll have more room to work with when editing. But if the C920 has a better overall sensor, I would choose that instead. I’d love to know what you think…

    • Saulius Lukšė
      2013-10-24 07:16

      Can’t really tell which one is better in photo mode. But for stop motion I would go for something better than webcam. Although if you need video, chose C920 – it has hardware h.264 encoder.

  7. Syreeta
    2013-10-24 09:42

    Thanks for the reply. I did used to have a DSLR, but it was huge and I was afraid that I would wear out the mechanical shutter with all the frames I need to capture. A webcam is easier as you can just grab and image from the live video stream and it’s small enough to fit on an animation set. This is why I’m trying yo get the best of both worlds: a high resolution webcam with good quality lenses.

  8. Syreeta
    2013-10-24 11:23

    Me again.

    I’ve decided I’m going to get a C910 just because of the 5 MP sensor. At least I will be able to zoom in and crop full 5 MP still images without losing too much detail as I plan to use the webcam WITHOUT Logitech’s software. Can you tell me if your new housing will work with the C910 PCB? I know the webcam itself is bigger that the C920, but I don’t know if it is the casing or the actual PCB that is bigger…

    • Saulius Lukšė
      2013-10-24 13:35

      Hi Syreeta, I have no C910, therefore I can’t tell if board is the same size.

  9. Syreeta
    2013-10-25 00:25

    I found a couple of links showing the internals of the C910 (click “photos” for the images for the first link):

    http://arts-tech-creation.blogspot.co.uk/2011/08/hack-deconstruct-c910-logitech-webcam.html

    https://plus.google.com/photos/116191926796960501293/albums/5710656019054643233

    Seems that there are two PCBs inside the C910! I wonder if it’s possible that the mics and camera sensor are both separate? Could there be a way to run the sensor alone? That would make it really small! Or maybe even exchange it for a better sensor! Maybe I’m overlooking things, but it really is interesting.

  10. Saulius Lukšė
    2013-10-25 06:30

    Can’t really tell, but looks like you need both boards and it will certainly will not fit C920 casing. I would not spend my time messing with it the way you have described :)

  11. Syreeta
    2013-10-25 11:21

    Is there any chance of seeing some footage from your modified C920? That would probably be the best in seeing if the C920 is worth it. I have tried putting a different lens on the C920 once (even making a custom lens mount for it out of resin), but it didn’t work out so well as I couldn’t figure out the distance the lens needed to be from the sensor and also what size lens was needed. I’d love to see what C/CS mount lenses can do with this webcam!

  12. Saulius Lukšė
    2013-10-25 11:31

    I have none assembled camera left. But with megapixel lens (i.e. high quality) picture is really nice. Sure this camera has limitations (bad low light sensitivity, dynamic range). It should be used in daylight or good light conditions.

    2014-01-05 07:34

    Email me. Interested in buying the case!!

  14. Syreeta
    2014-01-16 01:07

    Are you still making these? I would like to see how well it works, since I can’t find a better webcam near the price of a C920. Please let me know…

    2014-05-01 17:59

    I like your project, thanks for the writeup!

    Do you have the physical dimensions of the CMOS chip in the C920 (ie, millimeters height x width)? I’m looking to modify a webcam to take M12 lenses, and I want to calculate the angle of view before I commit to a camera. I really just want to know what webcam has the largest imager. =) People say the C910 has a “larger” sensor–do you have info on that camera?

    • Saulius Lukšė
      2014-05-02 16:09

      Hi Jesse, C920 6.00mm W4.80mm H3.60mm (16:9 format), I do not have information about C910 sensor size, but looks like it is has 4:3 aspect ratio and has bigger height value. So dimensions are bigger.

        Thanks Saulius, that’s very helpful!

  20. 2014-06-12 04:15

    Hi there. Nice work!!

    Can you tell me a little more about how you installed the lens? Is it screwed to the case or did you add a mount to the PCB?

    Cheers,
    Jose

    • Saulius Lukšė
      2014-06-12 07:26

      Hi Jose,

      There is thread in enclosure. No mount on PCB.

      • 2014-06-12 21:41

        Interesting.

        Can you comment on the lens specs (FOV, F, brand)?
        Also, is there a noticeable difference between the stock lens and a CS mod?

        • Saulius Lukšė
          2014-06-12 21:46

          Jose, most Megapixel lenses will work. You can chose any lens you wish ranging from fisheye to telephoto. Or you can mount on microscope and replace >1k$ camera. Or you can shoot in IR or UV range. Don’t get me wrong – Logitech’s lens is pretty good, but it is has annoying auto-focus and fixed zoom.

  21. Indel
    2014-06-12 21:12

    Hey there, that looks just awesome and I bet the image quality is far better with a lens like that. Do you still sell this case?

    • Saulius Lukšė
      2014-06-12 21:16

      Hi Indel, I am arranging MP right now. I have new design and cases should be anodized in black color. I will let you know on any further updates.

      • Indel
        2014-06-12 21:27

        Sounds perfect. Please do keep me updated, I will definitely buy one!

    • Saulius Lukšė
      2014-06-12 21:42

      Teaser :)

      • Indel
        2014-06-12 22:08

        That looks really nice. Is the mounting block still removable?

        • Saulius Lukšė
          2014-06-13 06:33

          Indel, mounting block is not removable anymore. It’s cheaper this way. Do need it to be detachable?

          • Indel
            2014-06-13 07:37

            It would be better for me if it was detachable. Would look much cleaner and would make it easier to put on my own mount.

          • Saulius Lukšė
            2014-06-13 07:56

            I see. It’s kind of to late to change for current samples. If there is demand, I will change back to 3 piece design.

          • Indel
            2014-06-13 09:31

            I guess I can just shave it off and repaint it.

          • Saulius Lukšė
            2014-06-13 09:32

            If you need >10 pcs, I can make what ever you need.

  22. Saulius Lukšė
    2014-06-16 11:43

    For everyone, who still needs cases – finally ordered samples. As I said before, these will be sandblasted and anodized in black color.

  24. Fabian Buntz

    Hi,

    first of all the idea sounds great, I need something like that for my Logitech C920.
    Is there an infrared filter integrated? Or is there just a hole in front of the sensor between sensor and lens?

    With this mount, can you place the webcam exactly in the way that the optical axis of the lens matches the center of the sensor?

    Would you send this mount to Germany?

    Kind regards, great job so far!

    • Saulius Lukšė
      2014-07-02 12:21

      Hi Fabian,

      * Infrared filter is absent, you have to take care of it by yourself (use appropriate lens or attach filter to matrix).
      * Correct. CMOS is aligned with mount.
      * Sure I can send to Germany.

      Write me an email for further details.

  25. Saulius Lukšė
    2014-07-07 16:46

    This is really cool and it might work perfectly for an application I have but is there a way to keep auto-focus working?

    • Saulius Lukšė
      2014-10-30 08:15

      Hi Matt, I have not tried this, although should be possible. Though you have to have lens with digital focus circuitry and add some circuitry to interface C920 to your lens. C920 has floating lens controlled by simple DAC (I have not measured what exactly is happening on these pins but there is direct connectivity to lens focus coil)

      Of course, there were few larger orders and I am temporary out of stock (have only 2 left and will re-list in a few minutes on eBay). I was in China last week meeting manufacturer and ordered next batch. I think I should receive next batch this year.

      • JP
        2014-12-19 23:08

        I got 2 casings from you, but I just realized that I am missing one usb adapter circuit board and 4 screws in the package (to Clemson University). Can you ship those when we order 6 more the next time? I assume that you will re-post your casings in ebay sometime soon, right?

          2014-12-19 23:54

          Dear JP, I am terribly sorry to hear this. There was some mix-up. I will resend missing parts in any case.

          If you are willing to wait, new cases will be re-listed in eBay in a week or two. New batch is is manufactured and on the way to me now.

          Please let me know if you would like to get missing parts sooner.

    Hi there,
    You did some amazing job with that camera.
    I am currently using two of them for medical purposes. I’m a French MD looking for motion control during treatment. I managed to perform some real time analysis of movement with OpenCV, and C920 just does the job. However, I would like to improve focus on the body parts i’m monitoring, in order to get more accuracy and maybe decrease CPU load by reduction of camera resolution.
    I’m not much knwoledgeable in this field, so I was wondering if you thought that I could adjust a manually controlled zoom to your case.
    If the answer is positive, then count me in for 2 cases and their lens, I’ll buy them on ebay.
    Cheers,

      Hi Mark,

      Thank you for kind words! I was always inspired by computer vision applications, and actually that was the purpose of this case. Actually by using this case you get rid of original optics and can use any CS or C type lens. These lenses are controlled manual way. Usually this is focus, but can be iris (aperture) and zoom. Google for “2.8-12mm Manual Focal Iris Zoom Lens” example. Do you have skills and tools to rework original C920 cameras or you need a service to put electronics inside aluminium cases I produce?

    Hi !
    Do you mean soldering tools and so on?
    I don’t have any at the moment, but I guess it must not be that complicated to get my hands on it. Same thing for the skills. I used to be an engineer, albeit not a very skilled one.
    But I wouldn’t mind a screwdriver or two in the package, and maybe some advice if I get stuck ;-). And if I REALLY get stuck, I’ll be happy to pay for your services.
    I think what you sell is exactly what I needed to finish my prototype. Please let me know how I can cite your work in publications.

    All my best,

    Marc

    • Saulius Lukšė
      2015-02-23 07:44

      Hi Marc, actually assembling camera is not that complicated. Most complicated part is to solder 5 wires. Tolerances are tight and using wrong tools might occupy some tome to accomplish this rework process. I would be glad to help you if you have some problems reworking C920 cameras.

      Just to make sure – What publications are you talking about?


      BR,
      Saulius

      • Mark
        2015-02-24 03:53

        Scientific publications. Basically, technical publications of some sort in medical journals.

        What do you mean, tolerances are tight? What tools do you recommend?

        • Saulius Lukšė
          2015-02-24 08:51

          Actually anyone with basic skills of electronics can handle rework process. There is one place on C920 PCB where you need to scrape green solder mask with scalpel – to be able to solder GND wire. Soldering 5 wires from included USB board to camera is also not a big problem, just soldering iron must be equipped with fine tip. Everything else is common sense (dismantle original C920 case, unscrew lens and unsolder focus wires, collect screws PCB holding screws and use these for assembling into new housing, solder 5 USB wires – recommended length of these are documented). It is a bit tricky part screwing M2 screw to hold USB board in place, but using included ball allen key helps a lot.

          This camera has part number – LP0144. In a reference you can state my web page and or my name.

            Hey Saulius,
            I received the parcel a week ago. Seems like they mistook my island for another one with the same name but part of Dominican Republic…
            Everything I received is great and works very well, but you forgot (or the customs??) a mini usb chip and the screws for the second case…

            Apart from that issue, I’m very satisfied. Cs mount adaptor is very convenient.

            2015-04-04 18:48

            Hi Mark, I am so embarrassed to hear this. This is totally my fault – I will resend you missing parts as soon as possible free of charge.

          • Mark
            2015-04-04 19:17

            It is ok really, one case is sufficient for the moment for demo purposes.
            If you resend the parts, do you mind sending them to my parents’ instead?
            It seems that it is much faster if it reaches France mainland before the island. They will send it to me afterwards. Besides, it will be much cheaper for you.

            Hi,
            I noticed I kind of dirtied the sensor while manipulating the elements.
            Do you have a tip to clean it without endangering it? I actually think I might have damaged it while soldering.

            Also, I think I might need a couple of cameras more. Would you consider providing a service to rework the camera with your case? I would feel more confident if you did the job. If so, what would be the cost?

            Cheers !

            Hi Mark,

            Indeed reworking is delicate job.

            I clean sensors with DSLR camera cleaning kit (liquid, swabs, cloth, sticks, dust blow,…)

            Actually few days ago I have listed two complete reworked C920 cameras on ebay – feel free to check http://www.ebay.com/itm/151639773920

            Just what I wanted !
            However, do you mind putting an IR filter inside and setting in up in usual position?
            I would like ti minimize dust on the sensor and I need a filter aniway.

            Please tell me what is your price and how I could pay you.

    Hi there, I was wondering if I could ask a few questions regarding the case, IR Filter and CS Lens’. I work for a creative advertising company and we use the c920 inside custom made screen enclosures that we fit with touch screens and original interactive games. currently we are trying to customise our c920’s to use in our enclosures. Your case clearly stands out as a great looking alternative housing.

    My question is how well can the case with a CS Lens be used, still in a webcam style application? The Premise is simple. A member of the public approaches a 60″ portrait oriented touch screen running our custom app and sees themselves. Once on screen they are subject to a comical display of augmented reality eg. Dress up masks and party hats which follows them as they move. (This is just one example of a app we have)

    My knowledge of lens’ is nonexistent.

    Currently the c920’s inbuilt lens works perfect as-is with the app. However as I mentioned we must house the camera in a custom made box as the camera needs to be fitted to the custom ‘experience enclosure’ (The housing of the screen, pc, webcam power etc./ The behind of what the public sees…)

    could you recommend a lens that would work for this application? it needs to be as clear as possible so that the person playing can clearly see themselves.

    I’m currently in charge of sourcing and organising a solution for our enclosures. I’m very keen to purchase these, as if all goes well with this, there will be a larger ongoing volume of these being made. They will be used in all future product we make. (please email for potential numbers)

    I’d be absolutely humbled if you could please help me in anyway at all :)

    Is there a low cost CS lense that is in the same league or better than the internal carl zeiss (apologies if thats a dumb question) we obviously want the best quality for our applications.

    could you also provide any information on how the IR stuff works as well.

    Thank you in advance!

    • Saulius Lukšė

      Hi Shane,

      It is a pleasure for me you have stumbled upon my blog!

      Lens. To be short I can recommend 2.8-12mm variable zoom and variable iris lens. This should suit most of the needs when used indoors. View angle can be adjusted in a range of ~25..100 degrees. Or in some cases I go with 1.55mm fish-eye lens, if distortions are not a problem for you. It would give you ~180 degree view field. I know verified supplier in China for these lenses and have several samples. I am not officially selling these at the moment, but working on this. These lenses are pretty high quality. I don’t have tools to measure how well they perform compared to carl-zeis one, but they are definitely in the same league (not sure – slightly better or slightly worse).

      IR filter. By removing stock C920 IR filter camera becomes sensitive to IR part of the light. This is good if you want to have infrared lights, but image will be black/white (reddish actually but mostly this carries no useful information, therefore mostly converted to black and white). That’s why I have measured precisely in optics laboratory Logitech C920 original IR filter and ordered custom made ones. These behave exactly like stock filters, therefore color of captured picture remains unaltered.

      If you need more details, please send me an email or we can have skype talk.

    Hello Saulius are you still selling the IR filters for your case on Ebay I can’t find them listed anymore. I was using The C920 cameras to live stream events but was always frustrated like you that there was no optical zoom possible. Your case is exactly what I was looking for so i ordered 2 of them today along with two lenses 5-100mm I can’t wait to put these together and see the results.

    Hi Saulius,
    I am a complete newbie with computer vision. I have previously removed the IR filter from a ps3eye camera, and used floppy disk material as a bandpass filter, however, the focus was horrible. OpenCV was giving runtime errors with the camera so now I am working on a project and am looking to remove the IR filter from a Logitech c920. How can I fix the focus on the camera? I read through the thread and see that a CS mount is mentioned. Would a CS mount eliminate the focus issue?

    Any help is very much appreciated.

    Thanks

    • Saulius Lukšė
      2015-03-09 07:51

      Hi Tiffany, indeed using CS lenses would give you much better results (you will be able to focus manually). By the way I am working on manufacturing custom IR band pass filters designed for this enclosure. I hope I will have them in a month or so.

    I will use it together with a Samsung Galaxy Note 10.1 and the app USB camera Standard for viewing what the students do under the microscope an much cheaper options compared to installing side tubes (5000 EU each) and it also give me the option to take pictures or save video

    • Saulius Lukšė
      2015-06-23 07:22

      Hi Xinming, just add 5mm extension ring and you can use C-mount lenses.

  73. 2015-06-23 09:36

    can I buy 2 5mm extension rings, I have 10,20 and 40 but not 5mm

    • Saulius Lukšė
      2015-06-23 09:39

      C-mount and CS-mount lenses have different focal plane distance.

      CS = 12.50 mm
      C = 17.526 mm

      So difference is 5.026, which is why 5mm spacer ring is used to adapt C-type lens.

    I think that I need a spacer for the microscopes that I intend to use the modified c920 cameras and my questions is can I buy 2 of these from you?

    Received new batch of C920 cases. I tried to notify everyone who was interested, but if I did not by mistake, please check re-listed items on eBay.

    Would you mind sharing your 3d model (if you have one?). I have a RepRap 3d printer and would like to print your case. It might be a challenge, but I’d like to try it anyway.

    Thanks

      Hi Andre,

      printing case with 3D printer is not a good idea – it will not have stability and precision required.

      Also I have put some amount of work into this case, therefore 3D model is not shared for community. Hope you understand this.

        Hi, I understand 100%!

        You did a really good job with it, I’ll see what I can manage on my side with a 3d printed version. I mostly only need it for indoor use, so it doesn’t need to be that stable and precise.

        Thanks for the honest reply :)

          Hi, thank you for understanding. If for whatever reason you should decide that you need aluminium case let me know, I will give you better price.

  77. 2015-08-02 11:08

    I’m thinking about using a C920 for live streaming an outdoor event. The original case can be weather sealed probably with a bit of Plasti Dip. Your CS-mount case plus a zoom lens is quite tempting – but how would you weather seal it?

    • Saulius Lukšė
      2015-08-02 18:34

      Hi Felix, I am happy you are interested in rework case, while it works perfectly with CS lenses, it lacks weather proof features, so you should put it into some outdoor rated enclosure (like CCTV cameras are used).

    Wow! I recently purchased a C920 and just stumbled across your case.
    Pretty cool! Unfortunately I don’t have much use for one that I can think of, but it does look like a fun project and it looks awesome!

    I did check out your other blog entries and, wow. Awesome!

    Tank you very much!

    Got the case yesterday, and assembled it this morning. It’s a neat piece of engineering!

    Now, for some minor issues that could perhaps be improved:

    The screws saved when disassembling the original case didn’t work for the PCB. Even with a lot of force, I was not able to drive them all the way into those threadless holes. So I used shorter screws, also from the original case.

    The filter could have a larger radius, then it would stick better to the double sided tape.

    • Saulius Lukšė
      2015-10-14 13:24

      Hi Felix,

      Thank you for notes! Indeed you must apply some force to screw these tiny screws, but I had no issue so far (no broken screws or twisted caps). Of course decent screwdriver is recommended. Also glad you solved this issue with shorter screws.

      What’s about Ir filter – it was designed to fit from top and bottom sides so I could not increase dimensions. Anyway I have learned from my trials with filters and have updated filter mounting design – it is already incorporated into new camera. Will share specs and pictures this week.

    Hi Saulius,

    It seems I have joined the party late – I found your site while searching for ‘C920 inside’ on Google Images, as I wanted to see how I could disguise/house the camera better in a research lab.

    Firstly, great work – I can’t wait to read up on your instructions and start my own project.

    Are you planning on getting any more cases made anytime soon?

    Best,
    Tom

    Hello,

    I am interested in adapting the c920 for close focus work. Specifically to 1) view small print items on a PC monitor and 2)perform screen capture and OCR on the images. Not being familiar with lens, can the 2.8 to 12 mm zoom lens provide relatively close focus and suitable magnification? I am a person with low vision and don’t want to invest in a stand-alone magnification system for reading.

    Please let me know what you think.

    Regards, Jon

    • Saulius Lukšė
      2016-02-01 07:55

      Hi Jon, with 2.8-12 lens you can focus from close distances and achieve result like macro. However I don’t know how do you plan to use it – in macro mode camera has to be held pretty stationary.


      BR,
      Saulius

  87. 2016-02-12 16:45

    Hi Saulius,

    Impressive photo. I can’t say when I would need a macro function, but I can envision it. The bulk of my application would be to magnify text for screen reading. Ideally at a distance of 20-30 cm from the front of the lens. The standard c920 is a bit fuzzy with near objects and the typical text size on screen is not large enough to be a help.I am also considering building a light stand to provide even illumination of the page under the camera.

    Hello there, could you possibly let me know when you will have more of those Logitech c920 enclosures available? I would like one so I can mount my camera on a Vortex HD spotting scope to monitor hits on targets at the range.

    • Saulius Lukšė

    Thanks for uploading the details of your product. I would like to buy your product but I am in India and we have an urgent requirement for this case. I would be really grateful if you can share the 3D model of the case with me.
    If you are able to ship to India I would like to buy 5pcs also.

    Just noticed that the front tube of the 2.8-12mm CS 1/2.7″ 1:1.4 lens easily comes lose, means I can remove it. Can it be fixed?

    Otherwise, I’m very happy with the case and the lens! Just used it to record a short video. Here I wonder if there are better applications than the Logitech Webcam Software. In particular, I’d like to have a higher resolution preview.

    • Saulius Lukšė
      2016-05-05 19:07

      Hi Felix, the very front ring (3mm) can be safely unscrewed. This is decorative ring, maybe it was not tight enough or loosened during transportation. Fell free to screw it back while holding tube with lens information on it.

      Or if I misunderstood your problem let me know, I will replace the lens.

    Hi!

    I was thinking of using the microsoft lifecam studio webcam (also 1080p) for a diy lens hack,
    http://www.diyinhk.com/shop/usb-microscope-1080p-for-smt-soldering/51-lifecam-studio-1080p-microscope-lens-mod-kit.html

    but would much prefer using the logitech c920! Does the lens at kurokesu shop (CSLZFAA2812) do 10-50x magnification – suitable for smt work?

    If so, can the focus be adjusted by hand, or only via electronic controller & software?

    If the lens AND controller are needed (i.e. PCBA_CTRL_ZOOM1_BUNDLE), is this bundle designed to fit in the case (KITC920)?

    Because the original lens has filters built-in, will using the above lens upgrade on the C920, require ir filters?
    http://www.kurokesu.com/shop/image/cache/catalog/c920%20kit/IMG_5390_r2-800×600.jpg

    Can you point me to what product(s), I would need to upgrade my C920 for 10-50x microscope work?

    Thanks!

    • Saulius Lukšė
      2016-07-11 06:43

      Hi Ben,

      I owned few microsoft lifecams, but they were buggy after some time USB connection closed and in order to restart USB had to be re-pluggyed. Maybe this was only my experience. Also C920 and C1 has much better picture quality than MS camera.

      PCBA_CTRL_ZOOM1_BUNDLE is fully compatible with any CS type camera, including C920 rework kit and C1. Just I am not sure if there will be enough magnification for your application. (C1 has integrated filter, reworked C920 has optional filter mounted inside the case)

      For SMT rework I’d recommend using microscope lens (not particular one, but something like this http://www.ebay.co.uk/itm/310781032908) Other kind of lenses while might focus at close range, not designed for large magnification.

    Hi,

    I am very impressed with the casing that you have made for c920. I am planning to use that array with an objective lens for my application. Are you aware of any adapter that may fit the objective lens into a CS mountable casing?
