Sounds to me like a technique thing, zVratko.
The Oly, the Fuji and the K3 are obviously fine cameras, but do not yet have a socket for a cable plugging into your brain to read your intentions.
What you have is fine if you choose centre point focus only, and do the half-press, recompose routine.
Otherwise all those other cameras can choose something else to happily zero in on.
Not important if you're doing a landscape, very important if you're doing an event with lots of foreground/background objects, people walking around, etc.
For instance, if you do wildlife photography, every camera claiming to have the world's fastest AF system can just lock again and again on the leaf in front of the bird.
