Recommended Lens brands...etc....
« on: October 09, 2017, 07:48:20 PM »
I have started with just a simple Computar M1214-MP2 (12mm prime) lens.  I also have no idea of Computar lenses are high-quality, low-quality, or middle of the road.
I have shopped around, but I have no experience with the variety of lens manufacturers that make C-mount lenses.
What brands should I consider?
And who should I avoid?

Also . . . should I invest in a variable focal length, or stick with fixed focal length?  Not sure what would be best suited for getting started.

I will primarily be photographing firearms function.  But I am sure that my three sons will also come up with other uses!

Thanks.

If you want the clearest image possible you need as much light as possible, it doesn't matter if you have a $10k cinema lens or a $10 eBay special, more light = high image quality.

With that out of the way I would recommend using 35mm, manual focus, manual aperture, SLR lenses (60s/70s) for a couple of reasons. They are fairly reasonably priced, you can get lenses as cheap as $20. Also there are way more choices in the 35mm Nikon/Cannon/Yashica/Konika/etc. range than you will ever find in native C mount. That will give you a huge selection in focal length and aperture (and bigger aperture gives you more light). Finally you will also get a better image in general out of a 35mm lens on a c-mount camera because you are only using the center of the lens, where it is sharpest and has the least aberrations.

The one big drawback is the crop factor, the Chronos sensor is 2/3" which is 3.9x smaller than 35mm film. So a lens that would give a wide field of view on a 35mm camera will be very zoomed in on the Chronos. If you have the space it is easy enough to just step back a little (or a whole lot) to get your subject in frame.

That's pretty much exactly my plan: using a F-mount to C-mount adapter and some Nikon lens (the first one will probably be a 35 mm prime) and also the 12.5-75 mm Computar C-mount lens ;)

I already have the 12.5-75 lens and the adapter, now I need to hunt for a cheap Nikon lens :)

I just tried shooting with a canon EF 50mm 1.4 prime - looked quite good at initial glance! But with 3.9x crop, it is quite the telephoto. Have ordered a 14mm Samyang lens with canon EF mount too, that corresponds to 55mm which should be quite useful focal length...
