”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.”
This is a full-frame image at the minimum sensitivity of 64 ISO.
At 64 ISO the image quality is very good, with no noise problems, although the green saturation could be higher.
Still no major issues at 100 ISO.
Noise is visible at 200 ISO, but the image is still perfectly usable.
There is a noticeable drop in image quality at 400 ISO as the noise reduction system goes to work.
All fine detail is lost at 800 ISO, and the image looks blurred.
Image quality is very poor at 1600 ISO, and this setting is best avoided.
This is the full frame at 1600 ISO.
