A range of test shots are shown over the next few pages. Here, the full size image has been reduced for bandwidth purposes, and a crop taken from the original full resolution image has been placed below it in order for you to gain an appreciation of the overall quality.
1/40th, f/2.8, ISO 64
At the lowest ISO setting, as usual there is no image noise. I tried to move the rudder on this boat and was shouted at by the owner, who I didn’t realise was standing behind me.
1/60th, f/2.8, ISO 100
Up 1/3rd of a stop to ISO 100 and there is still no image noise.
1/125th, f/2.8, ISO 200
At 200 ISO there is some slight colour noise in the darker areas, but the picture is printable.
1/250th, f/2.8, ISO 400
At 400 ISO the colour noise in worse, and a lot of fine detail has been lost in the noise reduction process.
1/500th, f/2.8, ISO 800
At 800 ISO there is a high level of noise right across the image, especially in the darker areas, and image quality is seriously compromised.
1/125th, f/8, ISO 1600
At 1600 ISO the level of image noise is so high that the picture is pretty much useless.
1/250th, f/8, ISO 3200
At 3200 ISO the image size is automatically reduced to 2048 x 1536 (3MP). The noise reduction system has removed a lot of detail and the picture quality is awful.
1/640th, f/8, ISO 6400
I think Olympus just added 6400 ISO so they could claim the title of highest ISO on a compact camera, but when the picture quality is this poor, why bother?
