Thanks Steve.
No good reason, except that I'm so used to taking multiple frames for an image, to goose up the res and size for lg format printing, that a wide angle hasn't seemed desirable.
Perhaps with the 5DMKII, which I just got to replace my color 5D, there's enough pixels for more one frame wide-angle shots.
I suppose also that I'm thinking that with a 90mm I can get closer with more detail and less distortion using the multiple row technique. Does this all make any sense?
Thanks again.
