A range of test shots are shown over the next few pages. Here, the full size images at the minimum and maximum ISO settings have been reduced for bandwidth purposes to let you see the full image, and a series of crops taken from original full resolution images at a range of ISO settings have been included in order for you to gain an appreciation of the overall quality.





This is the full frame at minimum ISO.





At 50 ISO the picture is sharp and clean with excellent detail.





Very little difference at 100 ISO.





At 200 ISO there is some luminance noise, but colour reproduction is unaffected.





At 400 ISO the noise reduction kicks it up a notch, reducing fine detail.





Image quality is much worse at 800 ISO.





At 1600 ISO there is very little fine detail left.





This is the full frame at maximum ISO.
