Pentax Optio W30 Review - Test shots – ISO performance Review

”A range of test shots are shown over the next few pages. Here, the full size image at the minimum ISO setting has 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 placed below it in order for you to gain an appreciation of the overall quality.”

At the minimum ISO setting of 64 the image is nice and clean, with good colour rendition.


—-


Likewise at ISO 100.


—-


Still no problems at ISO 200.


—-


At 400 ISO there is some light noise, with random colour speckling in the darker areas.


—-


At 800 ISO the noise is much worse, and visible over the entire frame, but there is still some fine detail.


—-


At 1600 ISO the noise is now quite bad, most fine detail is lost and the colour balance is distorted.


—-


At 3200 ISO this shot is over-exposed by about one stop, but even correctly exposed the the image quality is very poor at this speed. The DSP mode will automatically choose this setting in low light conditions, so beware.
