Chronos User Discussion / 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.

Chronos User Discussion / F-stop when using lenses from 35 mm camera
« on: October 06, 2017, 08:44:13 PM »
Folks - first post here - my camera arrived a few weeks ago.  Still rounding up other gear to put it to use.

Question . . . I already have a few old FD-mount (Canon) lenses . . . particularly a Vivitar Series 1 28-105 mm and a 70-210 mm.  I also have a C-FD adapter.  On using these lenses . . .  does the f-stop change?  If I set the Vivitar lens to f/4, does that still equate to f/4 on the Chronos?

Thanks - Glenn
