My Nikkor 75/2.8 on Bronica S ,bad infinite focus?!
      #610309 - 13/02/2008 07:35

Hello.

When I want to focus something on infinite I can cleary see the background unfocused sharply,actualy I cand see the focus plane stopping somewhere in front of me of about 15-20 m .
Apart of this I seems to have consistant slight back focus on my pictures focused in the range 0,5-10 m .

Could be possible to have a damaged lens/camera? I wonder how cand be this fixed , any saviour screw somewhere ..?
Thank you.

I'm not familiar with the camera, but is the focussing screen correctly installed? Not put in the wrong way round?

I bought a Rolleiflex 2.8F Planar from a camera club member years ago and it would not give correct focus and I found the focus screen was in the wrong way with the ground glass side on top.

Hello. I'm new to this forum so you may have solved this by now
The screen sits on foam and if this has gone soft and tacky it will change the height that the screen was set at and will need replacing. Have a look at www.dennisremick.com/bronica which gives lots of info on the older Bronicas and a review by Ivor Matanle from the AP
If you have trouble with this link type it in on Google or look under bronica classic medium format cameras
Hope this helps. Mick
