I don't doubt that FD gear is good, but I've not really used it. I happen to have a couple AE-1 bodies, two 50/1.8, 50/1.2, 28/2, 135/2.8, and a 300/4. The bodies work, but I have so many other camera systems I haven't tried them out yet (with film). The lenses look like great lenses and I'm awful curious about the 50/1.2 and the 28/2, but I've only tried the 50/1.2 on my m43 camera a couple times. Not the full and true experience, I know that. It really wasn't successful at all because I don't have an adapter that works with the nFD mount.
So how do folks use the FD lenses in these modern times? Aside from loading up one of the AE-1 bodies with film, I don't have any alternatives...but there must be some.
More specifically, would it be worth pursuing a way to use these FD lenses? Which method would be best? I have Nikon (D)SLR, Olympus OM, micro4/3, and Leica M systems as my primary 135 gear. (I have other 135 systems too, but they're more of a collection and all film stuff, no digital).
