Just curious. According to this site, The Chrosziel DV Follow Focus unit is "designed specifically for HDV/DV cameras — small and light weight. The DV Studio Rig/Follow Focus is designed as a complete unit with a fixed handwheel; one-sided operation. It can only be used with lenses equipped with a focus gear ring."
My question is: Could I use that follow focus unit with Nikon prime lenses if I attach gear rings on them? If not, why? And is the DV version "worse" than the "Pro" version?
Basically, I'll be needing an inexpensive follow focus unit to use with a set of Nikon primes, but I'm leery of the Redrock Micro version. Thoughts?
