Computar Lens H0612FI for 1 2 CCD Cameras C Mount New I | eBay


Not sure if this one is better than the pentax one because many complain the pentax 6.5mm is not sharp

This is a CS-Mount lens, not a C-Mount!!! I didn't see any CS-Mount-Adapter, yet.


It's only for 1/3" sensor!

OK, thanks for the catch.
I did notice the second one is for 1/3" but it might vignette a bit?

I was also looking into cosmicar/pentax 4.8mm but they are fixed focus.

I just noticed the C-mount lens I bought from eBay is for 2/3"... Is this a good or a bad thing as far as vignetting? I'm new to the whole C-mount lens thing.

All C-mounts I have met [wide/tele/zoom] have covered the full Q sensor (=no vignetting)....thanks/Erik

Since the Q sensor is 1/2.3", it should be covered by C-mount lenses that are 1/2, 2/3, or 1". But there will likely be some vignetting with a 1/3" lens.

Good info. I'll stay away from the 1/3" lenses. You guys are a font of information.

If you see a C-mount labeled as 1/3" it's probably a mislabeled CS-mount lens
which you can't use anyways...so there will be no vignetting... Thanks/Erik

[see example below of mislabeled CS-mount]
