Yes definitely. I own only manual focus lenses, and most are used old lenses and of terrific optical quality. I hate autofocus. I understand its use for wildlife, sports, and war zone journalism, but that's not what I do. I shoot a lot of astro, landscapes, and some portraits, and I have time to compose and shoot for all of these, and I don't want some gadgetry between my hand and the glass doing its own thing. There is good modern glass available, but it's not the stuff sold to consumers at consumer prices. In the consumer price range I've consistently seen better glass in used old lenses from the 70s to 90s. Before that it starts to fall off rapidly due to lack of anti-dispersive elements and good coatings, but there are still a few odd gems here and there from even before then. Oh and as a bonus, with manual glass I'm not tied into one ecosystem. I own about 5 or 6 brands of lenses; I can freely change my camera body brand and just buy some new adapters.
