Originally posted by RonHendriks1966 That is a little to fast. K-01, K-30, K-50 and K-500 share the PRIME M imgae engine wich is different from PRIME II and have all 12-bit RAW processing. So they are different from K-5 (not to speak about other brands). From these the K-01 has the slimmest AA-filter and thus is for the PRIME M series the sharpest in Image Quality. Not that everyone would see it or all lenses would get the most out of it.
For a beginner with kit lenses, the differences would be hard to spot, which is why I added "essentially" the same. Near enough same to equate to no,practical difference, in the present discussion.
