I've been wed to Nikon for most of my life, and have only used a couple of Canon film SLR's over the years. I recently decided to expand my film horizons and pick up a Canon SLR, or two, with the FD lenses. I bought an A-1, that came with a 50mm f/1.8 as the "standard" lens. I then added a Tokina 70-200 zoom and a Canon 24mm f/2.8 for my wide angle. I'm picking up a T90 tomorrow, and I've always liked the design as a sort of "Deco" manual focus film camera. The lines are beautiful. I'd also like to add another 50mm lens, this time in 50mm f1.4. There are several versions out there, some with the chrome breech lock ring, which are etched SSC on the face of the lens barrel, and some newer models which close down to f/22 and use the newer FD mount. I've read various opinions on the older models as being very soft wide open, and at f/4 have sharpened up considerably; and that the 50mm f/1.4 lenses in general, are not super sharp. I've also read that the 50mm f/1.4 was considered the "standard" by which others are judged. I'm not stuck on a 50mm f/1.4, and there are a couple other focal lengths that look interesting. Anyone have opinions, experience, etc.?
