Hi! I have a Canham DLC45 and currently own 3 lenses, 90, 135, and 210. While I absolutely love my Nikkor SW 90mm f/4.5, I have, on occasion, found need for something a bit wider. I have been looking at 75mm lenses like the Nikkor SW 75 f/4.5 and the Rodenstock Grandagon (MC?) 75 f/4.5. I'm sure lenses from the big 4 (Nikon, Rodenstock, Schneider, and Fuji) are all great lenses, my main concern is having to deal with those terribly expensive center filters. Are there any recommendations anyone can give me for a wide (and bright for focusing) lens in the 65 to 75mm range that the light falloff isn't so bad that a center filter is critical. To give you a good example of how I shoot, I usually shoot wide and up close, not architectural, but mostly landscapes and scenes such as old rusted cars, trees etc. I also find myself typically shooting between f/11 and f/22 most of the time with the occasional f/32 here and there, so shooting wide open isn't an issue.
Thanks for any advice you can provide,
