I've got a boatload of older glass, many of which were sold as "Pro" quality at the time of their introduction & they all do well on digital. As for manually focusing an AF lens. it's the pits as AF lenses are designed for fast focusing, not precise focusing. The "throw" ( how far the lens focus ring turns to get from min to max focus) on newer AF lenses is much shorter so that the camera can focus on a subject faster. Plus focus screens in modern DSLRs are optimised for AF as well. Gone are the focus aids from older manual focus cameras (split screen, microprisms). What's nice is that you have more upscale bodies that allow for metering with those older lenses.

Was just wanting to see how sharp the old glass would be, am pleased with the initial results. I like/prefer manual focus; I get to choose and anchor the shot exactly where I want it to be. Not sure I trust the manual override on an AF lens unless I can turn off the AF completely.
