Olympus E-M1
In reply to MinAZ, Apr 26, 2014

I've owned a J1. I also have currently an E-PM2, and E-M1.

As far as actual speed to focus on a static subject, I don't feel a difference, but there's more to it.

The E-M1 AF performance comes closest to the J1 but still falls short. The continuous AF (PDAF) area is smaller, with half the number of AF points. And in my opinion Olympus' AF algorithm gives up on PDAF way too easily and falls back on CDAF (hunting) when IMHO it should just hang in there (or give us a PDAF-only mode!).

The E-PM2 AF performance is not comparable to J1 if the subject is moving around too much.

Still I prefer the MFT cameras over the J1 for other reasons, which I'm not sure you want to get into in this thread.
