Pentax Optio M60 - 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. These ISO test images are shot indoors using reflected natural light for maximum consistency.

----



The full frame at 64 ISO, the minimum setting.

----



At 64 ISO the image quality is good, with no visible noise and good colour reproduction.

----



There is a hint of chroma noise at 100 ISO, but overall quality is good.

----



Noise is clearly visible at 200 ISO, but still no major problems.

----



Noise reduction is causing some loss of detail at 400 ISO.

----



Significant levels of noise at 800 ISO, but still plenty of detail.

----



Pixel binning at 1600 ISO has greatly reduced the level of detail.

----



3200 ISO is restricted to 5MP, and picture quality suffers accordingly.

----



6400 ISO is also limited to 5MP, and picture quality is even lower.

----



This is the full frame at 6400 ISO.
