    Rated 5 out of 5 by from Great Lense This is a great lens. The image quality an clarity and color captured meets my expectations. I found that the advertised data was exactly as listed and plan to buy buy more Computar lenses to add capability to my c-mount cameras ability to capture quality video. It has always been a pleasure buying from B&H.

    question

    Is there any vignetting with this lens on a Sony Nex 5N?
    Asked by: Anonymous
    This lens is not recommended for that camera as the lens is made for standard definition cameras and will lead to vignetting of megapixel images.

    question

    question

    Compatible with m43/GH5 ?
    Asked by: Michael H.
    This lens is designed for standard definition cameras, not high definition. While you could use an adapter, you won't get the best picture captured.

    question

    Will this work on a Sony A77?
    Asked by: Anonymous
    Not directly as this is a c-mount lens. The Sony A77 has a Sony Alpha/ Minolta lens mount so you would need to convert from the Sony format down to a c-mount which is not very common.

    question

    will this work on a nikon d3100 and will there be dark corners
    Asked by: jacob s.
    No. This lens is intended for 2/3" image sensors (11×8.8 mm), meanwhile APS-C cameras like your Nikon D3100 has a sensor size of (23.1×15.4 mm) which 3is considerably larger. You will experience severe vignetting even if you applied an appropriate adaptor.

    question

    I posted a similar question for Computar MLM3X-MP and Tamron M118VP413IR; I have a video camera C mount, 1/1.8 CMOS, 1280 x 1024, USB3 (Ximea MQ013CG-E2); I have to see at a distance of 025 -0.3 m., an area of , more or less, H=10mm., V=8mm.Is good this lens for me? Which is the better choise among the three lenses? Thanks a lot.
    Asked by: Vittorio C.
    This lens is absolutely not right for you - the minimal focal distance of this lens is much higher, like a meter or so.Check the NAVITAR lenses by ThorLabs, they will have something for your needs.

    question

    Hi,Is there an adaptor to use this on an e-mount VG20, with no vignetting problem?If not, could you recommend a similar fast manual zoom lens for e-mount?Many thanks,Jo
    Asked by: Jo C.
    I purchased this with a metabones adaptor. I had to use the clear zoom on my Sony a3000 one click to remove the vignetting.

    question

    is this compatible with bmpcc camera or does it need adapter?
    Asked by: alejandro m.
    this particular lens is needed to be modified in order to be used with BMPCC. it has issue with distance between lens and CCD, thus its own c-mount must be machined before put on an adapter from C-mount to MFT
