Nikkor Lenses Shift With Follow Focus
Posted 05 October 2009 - 10:27 AM
Whenever I switch directions with the focus.. say someone is walking away and then towards me.. the lenses shift slightly causing a little bump in the frame. Its especially noticeable when I use my focus assist.
I'm worried that the follow focus may be putting too much pressure on the lens or damaging them. I try to use the threads so the tips do not touch but I still see a slight shift.
Anybody else had this problem?

I have a few zeiss contax still photo lenses I like to use and certainly have better mechanics than nikons about the same age and have some dampening and no sign of loose bits, but even these lenses I find have a weird issue with the aperture blades closing into an odd pattern, creating some odd bokeh when shooting with the aperture 1-4 stops down from open (imagine a polygon with sharp spikes sticking out of it). Moral of the story is probably that still photo lenses made over 20years cant be relied upon. Next time I try to use still lenses for cinematography, I plan to test them very very carefully.
