Pentax Optio M40 - Test shots - ISO performance

Over the next few pages we show a range of test shots. 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.

----

----

Image quality at the minimum 50 ISO is very good, with no noise and plenty of fine detail.

----

Image quality is still good at 100 ISO, although there is a tiny amount of colour speckling in the darker areas.

----

Still no major problems at 200 ISO.

----

Noise is starting to reduce image quality at 400 ISO but the level of fine detail is still good.

----

Even at 800 ISO this would look OK in a small print.

----

The M40's maximum 3200 ISO is higher than average, but image quality at this setting is low.

----

The image is quite noisy at 1600 ISO, but I've seen lots worse.

----

This is the full-frame image at 3200 ISO.
