Nikon D7000 Indoor Crops

Here, the Nikon D7000 is compared to the Pentax K-5
Pentax K-5 which most likely shares the same image sensor. All images below are 100% unmodified crops from their respective cameras. Both cameras were set to F/8 in aperture-priority mode with fixed ISO and custom white-balance. As usual, the cameras were calibrated to give the highest quality and most realistic results possible. The Nikkor AF-S DX 18-105mm F/3.5-5.6G ED VR
Nikkor AF-S DX 18-105mm F/3.5-5.6G ED VR was used on the Nikon D7000 while the Pentax K-5 used the Pentax DA* 16-50mm F2.8 ED AL (IF) SDM
Pentax DA* 16-50mm F2.8 ED AL (IF) SDM.

These crops help determine which ISO settings can be acceptably used on these cameras. As image noise increases, most cameras compensate with noise reduction which introduces softness. The point at which a print become unacceptably noisy is a matter of personal taste.

While the sensors are the same, the D7000 uses more noise-reduction by default making its low-ISO results look smoother and its high-ISO results look softer. The Pentax K-5 has its default noise-reduction much lighter, showing more crisp detail throughout the ISO range but with slightly more noise.	ISO 51200
