645d resolution comparison: K5 / K10d / Leica M9 / Canon 5d MkII
Dec 29, 2010

Below is a real life resolution comparison. Purpose was to see how much real additional resolution the 645 provides compared to full frame or APS-C. Comparison is against K-5 and K10d with FA35mm, the Canon 5d MK2 with the 50mm L, and the Leica M9 with the 50mm Summilux. All shots at ISO 200, f5.6, 1/1000th. The 645d has a slightly unfair advantage as the 75mm lens is essentially a 60mm equivalent, whereas all the others are c. 50mm.

I resized the other files using BenVista photozoom so they match the 645d 100% crop.

Five examples below. Except for the 645d, I did not label them and erased the EXIF, so people can have some fun guessing.
