Currently I'm trying to master manual focus using E-M1 and Oly 12-40/2.8 lens. Never did MF before, because FF has very good AF lens for shallow DOF (like 135/2, 85/1.8 or 1.4, etc). Now, for m4/3 it's very hard to get similarly shallow DOF as on FF - best AF lens are Oly 75/1.8 (which translates to 150/3.6) and new Pana 42.5/1.2 (which translates to 85/2.4). So, I was thinking myself that if can master MF good enough, I can buy and use those Voigt or SLR Magic that are F0.95, which translates to F1.9 on FF - close enough to 1.8, and not too far from 1.4. I did set up peaking to "on", as well magnifying also to "on". Oly 12-40/2.8 is very convenient to use in MF - just slide focus ring to MF, and start shooting. Now, that's how I try to MF: choose focus point onto where I want to focus, then rotate focus ring until I see peaking lines to appear and magnifying shows me that subject is in focus, then press "focus lock" button (I assigned that to AEL button), then press shutter button. Problem is that no matter how hard I try - handheld or tripod, no matter how deep DOF is - my MF photos are NEVER as sharp as AF ones. At best they come very close, but never, ever I managed to get same sharp results from MF as I'm getting from AF. My question is - what am I doing wrong? May be there is camera setting that I overlooked (like may be lens correction needs to be set "off" or something like that)? Or, may be there is different technique I should use? Anybody can help?
