Hello everyone. Here's a tough question for you pro photographers out there. Although, I'm sure if not all of you, most of you shoot digital. Well, I sold my Canon EOS Rebel T3i and returned to film. At present, I shoot with two 35mm SLRs, a Minolta Maxxum XT si and a ST si. The XT si has a top shutter speed of 1/4000 while the ST si goes just to 1/2000. I also use a XG-1 with a Panagor lens for macros. I'm kind of looking for a 400mm or longer lens for wildlife shots, for the Maxxum SLRs. Does Sigma, Tamron, or Sony make an A Mount that long? Any suggestions and comments are really appreciated!Will
