Not sure which lenses you have and need, but there are many options among legacy lenses and not that many among :43: lenses. Adapted 4/3rd is an option. Another plus for legacy lenses is they're cheaper than comparable AF lenses.I am looking for a good portrait lens and everyone is telling me I need a legacy lens, e.g. a Canon FD 1.4 or FD 1.2(L).
The main difference is, of course, absence of auto-focus and face-detection. I know many people are ok with that for portraits, but I have no idea how they do it. I guess for group shots or formal portraits it should be ok, but for casual shots I would prefer AF.What do I need to know when I want to shoot portraits with such a lens? What are the main differences compared to shooting with a native M43 lens?
