I've been having trouble getting the correct exposure in my photos. I thought it was just me but now I'm wondering if it is due to light falloff on my wide angle lenses. I have a Nikkor 90mm f/8 and a 120mm f/8. And I have been using extreme rise. Enough that I have some vignetting int 2 corners. I resently tried some macro shots with a Schneider 210mm f/8 and it looked like the exposure was correct. How much light falloff can you expect from a wide angle lens? 1 stop? And how far from the center of the lens does it begin to become noticable?
Thanks
Chris
