My vision goes through cycles - right now I'm seeing "wider" and using the 90mm a bit more than the 210mm. But that wasn't the case three months ago, and the situation is likely to reverse again in a few weeks.
150, followed by 90, 210, 300 and sometimes the 65. On my 8x10 I use the 210 more often than the 300 (only have those two right now - both of them Fuji and shared with the 4x5 system through lensboard adapters - Wehman to Canham)
I use my Fujinon 90mmSW the most, followed by the 72mm Schnieder Super Angulon XL, my 150mm Fujinon, 210 Schnieder APO Synmar, and my "new" 300 mm Dr. Optics 300 Germinar. I want to replace the 90mm Fujinon with a Schneider 90mm Super Angulon XL in the near future. The fujinon is very very sharp, but a little bit dark at times.
I just won a never used Doctor Optics 180mm Tessar, looking forward to see what it can do.
