Made first shots with my Rittreck 5x7" with Fujinon SWD 90mm f5.6 and when I used some reasonable motion (not extreme) there was LOTs of vignette, unbareable.
On my medium format camera I never could make the same Lee filters (which I love!) with the same wide angle adapter to vignette, even with the widest of the lenses, but now in 5x7" 90mm LF it vignettes too easily. Note the special wide angle adapter mounts the holder the closest to lens as possible.
Only when shooting straight with no lens movement there is (barely) no vignette. I have 2 filter slots + a very thin circular polariser mounted on top. This is clearly too much for SWD 90mm on 5x7" to handle. I took away one filter slot (thus leaving just 1 filter slot on the Lee hollder) then I can do some very small movements, but barely livable like this.
I wonder if it's just way too wide lens to use filters on OR it is the speciefics of Fujinon's SWD 90mm f5.6 with HUGE front element (82mm filter thread) that is on the limit for the 100x100mm square filters?
Anybody else have the same experience with Lee wide angle adpater on very-wide lenses on their LF?
