Just bought an M3 with adapter, EVF, and 18-55mm lens to replace a G15. My primary use will be for non action pics, such as travel and similar. For action, I have a 70D. Will AF with STM lenses be adequate? How about EF and EFs lenses. No so much concerned about speed as they were OK on my SL1 but AF accuracy. Found that some IQ issues I was experiencing were really AF issues front/back focus which was eliminated with live view. The 70D has AF micro adjust which I now consider a necessity for an optical finder and very fast live view for everything but action. However, the 70D is not what I want to carry around for some travel. Thanks

IIRC, mirrorless cameras don't suffer from front/back focus because they use contrast-detect to confirm focus (they may still use phase-detect for initial acquisition). But that doesn't mean it won't quickly and accurately focus on the wrong thing.
