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 the full image at ISO 100

ISO 100 has very good noise control and tonality

ISO 200 maintains the fine detail and is noise free


—-


ISO 400 is very acceptable with just a little bit of noise creeping in


—-


ISO 800 has more noise but images are still usable


—-


ISO 1600 has an even distribution of noise but is still acceptable – just gritty
