DXOmark and sharpness tests K5ii, K5iis and K3
11 months ago

See http://www.dxomark.com/Reviews/Best-lenses-for-the-16-MPix-Pentax-K-5-II-and-K-5-IIs-Measurement-data-now-available-online  for their tests.

Now can anyone explain to me about their sharpness measurements? They say the K5IIs is 25% sharper than the K5II, but that the K3 is only 10% sharper than the K5IIs. That has me confused, not that I understand DXOmarks lens tests anyway. However removing the AA filter gives you 25% increase of their sharpness, but increasing the pixels by 50% only give a 10% increase.... I guess it could well be that the lenses cannot use the extra resolution because one of the sigma's showed a 23% increase?

Pentax K-5
