As digital photography technology continues to evolve, the changes that are coming to camera isn't just about pixel count anymore.
The changes increasingly are about delivering the best possible image, from how it is captured to how it is processed.
The Pentax K-3 II is among that group of cameras. While both cameras use an APS-C 24.71MP CMOS sensor, the K-3 has slightly higher resolution: effective 24.3MP vs. 23.3MP in the first model. The lens magnification factor is 1.5X.
