Originally posted by tibbitts Now I'm completely confused. I like my K-5, but that might be partly because I don't have an OMD EM1-ii. Of course a dslr is different than mirrorless, but I'm just not understanding moving from an EM1-ii to a K-5.
DxO mark score for the OM-D E-M1 MkII is 80 with a DR score of 12.8
For the Pentax the score is 82 with a DR score of 14.1
SO the difference in DR is 1.3 stops.
The technical specs don't favour the Olympus, although past experience would suggest differences of less than 5 are meaningless. But if your main concern is IQ, you might want to goto the Pentax straight up. As the physics would suggest, the Olympus costs you a stop and a half of DR.
The Olympus picks it up with a higher ISO value, but no where near a stop.
So just looking at DxOmarks scores, that's what comes to mind. With cameras so close in their scores, other reasons beside IQ will make a difference, and OVF instead of EVF is certainly one of them. You don't lose anything going to a K-5 in terms of IQ. The Olympuses 20 MP sensor kicking out higher ISO performance but less Dynamic Range would suggest a whole lot of anti-noise baking is going on in the Olympus.
This just from looking at the DxOmark specs. They suggest you might not gain much going to a K-5, but you're also not losing anything, so if an Optical viewfinder is the deciding factor, it's pretty much a no brainer, especially given current prices. If you're thinking the higher Dynamic range, doesn't mean much, I notice the difference between my K-3 and K-5, so that could also be factor. But, I suspect soon, the OP will be the expert on the topic, owning both cameras.
He'll know about the actual use of the cameras, which can't be determined from a spec. sheet.
