Hi everyone on the forum,
I have been using the Schneider 5.6/28mm with a center filter on my Linhof Techno with a Credo 40 DB for the last 3 years. The lens is fantastic overall, but in high contrast situations, I tend to have weird bright spots in the image (see attachment). Since I never have these problems with my other SK lenses (5.6/24, 5.6/35, 5.6/72), I tend to think that the 28mm lens might be to blame. I tried removing the center filter to have one layer of glass less, but the effect did not go away. Do you have any ideas what this might be?
best,
geb

What about keeping the light off the front element (flag etc.).

Hi geb
I also use the Schneider 28.
For me the bright spots look like internal reflections of the CF. If the spots stay without CF, it's maybe one of the lamps in the ceiling.
I had these spots also with the SK24 and SK 35 when I used them with the CF. Schneider CFs are in backlight situations very weak.
Have also a look at my last post here:
