A K-5 Vs K-5IIs Head-to-head Measurebation

Test shots were made with the same FA31 Limited lens under the same lighting and test condition from f/1.8 to f/11 with an addition test shot at f/5.6 with the "extra sharpness" setting:-

K-5: http://pentax.briefing-paper.com/1121 (in Japanese)

K-5IIs: http://pentax.briefing-paper.com/1864 (in Japanese)

In particular, the following is the side-by-side f/5.6 pair of the comparison shots:-


(Above: Left: K-5 100% Crop at f/5.6; Right: K-5IIs 100% Crop at f/5.6; Normal Sharpness; Lens Used: FA 31mm F1.8 Limited - Click to Enlarge.)

Btw, with the removal of the integral AA+IR filter of the original K-5, the K-5IIs seems to produce colder picture than the K-5, with a purple tint and tendency.

In fact, the amounts of details of the two cameras are close enough, whilst the K-5IIs pics look a bit "sharper" and "harder" on edges. The fortunate thing is that the focusing accuracy of both cameras is good enough. The K-5 pictures are yet a bit brighter, though, despite that a +1EV exposure compensation was applied for both cameras. Last but not least, the micro-contrast of the K-5 shots seems to be somehow better.

On this two crops right one is way sharper, and more natural to my eyes, no some yelowish fog over it.

BTW, Rice, who told you, that removing AA filter means removing IR filter as well? It does not.

I'm confused. I thought sharpness is micro contrast. If it isn't then what is micro contrast?

I bet, less than 1% of Pentax users will ever print such large image, to see the difference. IMO sharpnes of S is advantage for those wierdos who compare japaniese money crops.
