Studio scene comparison (JPEG)

This is our standard studio scene comparison shot taken from exactly the same tripod position. Lighting: daylight simulation, >98% CRI. Crops are 100%. Ambient temperature was approximately 22°C (~72°F).

Pentax K-7 vs. Pentax K20D

Let's start by comparing the K-7 to its predecessor, the K20D. Unsurprisingly the tone curves and color response on these two cameras are near identical. However, at its default settings the K-7 uses less sharpening than the K20D. While the K20D shows fairly heavy sharpening artifacts in parts of the frame the K-7 image is slightly softer but cleaner and no less detailed. It also responds well to a carefully applied unsharp mask in post production.

Overall at base ISO, with default settings and the right lens the Pentax K-7 produces detailed output that makes good use of the camera's 14.6 megapixel resolution. The tonal range and colors are natural . If you are a JPEG user there is not really a need for much tweaking of parameters, the K-7 delivers right out of the box.
