I've been testing Nikon primes to see if I can get any two to match for a side-by-side rig. It's a challenge because if the focus is a tiny bit different, there is a zoom effect. I am concerned that in the field I won't be able to see the difference on small monitors, and the slight change will spoil the 3D effect.
It makes it impossible to compare distortion between lenses to try and find the best match (I am purchasing 6 lenses at a time to give me a pool to pick from)
Is there anyone out there whose figured out how to successfully use DSLR primes? Is the only other option Zeiss, Red Pro primes or other Cinema glass?
