Anyone reading this running a DLSR alongside a mirrorless, or has experienced both worlds, I'd be obliged if you could advise w.r.t focussing accuracy and speed of focus. I'm finding missed opportunities in my street work due to inaccurate focus, and this is driving me nuts! I hear the bleep and have to assume the camera has hit the spot as the situation does not allow focus peaking, magnification or any of the focus assistance that comes with 4/3s; speed is of the essence. Looking on Flickr, nine times out of ten, images that are 'spot-on' in terms of focus are taken with a DSLR. That may be a bit of an exaggeration, I have to admit, but the balance does seem to swing in favour of the Canon 5D or similar. (Comparative weight is a different matter, so too is stealthiness.) Any views on this?
