Hi Jay

I use filter drawer and field flattener, it  show back focus and I setup near distance.
Can get focus then it's my back focus.

Attach pic my FF=FD=Camera line.

Thank you Taro --

I have a question regarding the Z61 and Field Flattener. Do you have to adjust the backfocus distance of the FF when using a 2" screw in filter? Do you use a filter wheel/drawer?
