>>4436891>Slow as fuck AF >Do AF adapters even exist for these kinds of lenses?>You have to switch both lens and camera to AF/MF, otherwise bad shit will happen.It could be fun, if they packed actually powerful motor. But in reality it's just better to have it built in into lens, motors don't cost much
>>4436936.>Until you realize that the focus groups of some lenses weigh less than an ounce and others weigh more than a pound.
With powerful motor you could drive both, lens could tell tell the limits for older lenses that didn't tell the limits, it could drive legacy mode. But this is not our reality, only good thing about it is the fact that these screwdriver AF lenses are noticeably cheaper now than as good portion of cameras can't use them with AF.
