Canon EOS 7D Review - Test Shots – ISO Performance Review

”Over the next few pages we show a range of test shots. On this page the full size image at the minimum and maximum ISO settings have been reduced to let you see the full image, and a series of full resolution crops have taken from original images at a range of ISO settings to show the overall image quality. These pictures were taken indoors using reflected natural light ”

This is the full frame at 100 ISO.

The live view contrast detection AF system has missed a bit here, but the image quality is flawless.

200 ISO…

400 ISO…

800 ISO. There’s a hint of mid-tone noise, but only just.


—-


Again a light burr of noise at 1600 ISO, but this is a perfectly usable shot.


—-


Still no serious problems at 3200 ISO. The noise is there, but it’s smooth and well controlled.


—-


Noise is quite visible at 6400 but it looks like film grain. Tonal gradients are still smooth there’s still plenty of detail.

Contrast is fading at 12,800 ISO, but this is far from hopeless.

This is the full frame at 12,800 ISO.
