Nikon D300 Digital SLR - Test shots - ISO performance

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 taken at the extended range 100 ISO setting.

----



Even using a tripod and self-timer haven't eliminated camera shale from this 100 ISO shot. There is no image noise at all though.

----



The lowest normal range ISO setting is 200, but here too the picture quality is flawless.

----



No visible difference at 400 ISO.

----



At 800 ISO there is a tiny amount of mid-range noise, but not nearly enough to cause a problem.

----



Fractionally more noise at 1600 ISO, but the photo is still perfectly usable.

----



At 3200 ISO there is visible noise in the darker areas of the frame.

----



Another extended ISO range shot, this time at 6400 ISO. There is quite a lot of noise, and colour saturation is also affected.

----



This is the full frame at 6400 ISO.
