This is the "Pro" model SRT, the motor-driven SR-M. At least as good as anything I have ever used. This is the camera I lusted after, when I was in High School. Now, I have one. Actually, I am looking for the 250 exposure Back for it
I know a photographer who worked his whole career for LIFE Magazine and ROAD & TRACK, who swore by the SRM. The attached 16mm F2.8 MC Rokkor Fisheye is also worth some coin. Some of Minolta's classic lenses have achieved an almost "cult status". Not to be sneezed at.
