”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. These ISO test images are shot indoors using reflected natural light for maximum consistency. ”
This is the full frame at 100 ISO, the minimum setting. The K-m can be set to 1/3 EV ISO settings, but we’re just showing the whole-stop settings here for brevity.
The image quality is excellent at 100 ISO, although the default JPEG setting is a bit over-saturated.
Still very good at 200 ISO.
Still very good at 400 ISO.
There is a little shadow noise at 800 ISO, but the image is quite printable.
Some shadow detail has been lost at 1600 ISO, but colour balance and exposure are still good.
Definitely a bit noisy at 3200 ISO, but even this would be OK for small prints or web images.
This is the full frame at 3200 ISO.
