Great Lense

By Wayne
Rated 5 out of 5
Date: 2016-06-04

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

Compatible with m43/GH5 ?
Asked by: Michael
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 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.
Yes, this lens could work for you, if you add an extension tube between the camera and the lens. C-mount extension tubes come in various lengths.

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.
