Originally posted by Na Horuk The K-50 will give you slightly softer images than K-01 due to the AA filter. But it is WR and has OVF and mirror. The K-5IIs is a top notch camera that has more controls and dials. Since you are not a beginner, I would say K-5IIs. But you might want to keep that K-01, since it is compact and nice for traveling (and peaking, for old manual lenses)
Hm, maybe it is worth keeping the k-01 and going with the k-5 IIs. That way I keep focus peaking for my many many manual lenses and have a backup that my brother can use when he wants to take some pictures on our outings.
I'll just have to vanquish the thought of getting a wide angle lens till I get my bonus or something.
