Well, the new SAFOX X in the K5II and K5IIs is night and day compared to the old AF module of the K5, which performed as bad that I finally sold the K5. The New AF module is not only more accurate and faster, it works also down to -3EV, which is hardly to be found in many cameras. And the "only" 11 AF points turn out to be pretty enough, especially as they also allow decent continuous AF of moving subjects. There are faster AF systems today (Nikon, Canon) but hardly to be found in m43 like EM5, which has one of the fastest m43 AF systems. Maybe the new EM1 will be able to top that.When I recently shot my daughters' party, I used the E-M5 and not the K-5 because the Olympus contrast detect AF is so much more accurate than the notorious K-5 AF which is more a hit and miss business. But ergonomically there's no question which is better: Pentax.
But as of state of today I am pretty satisfied withe the K5II and K5IIs AF performance and the EM1 would need to be a lot improved over the EM5, so that I would give it a try just because of AF.
