Olympus mju 780 - 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 ISO setting has been reduced to let you see the full image, and below that a series of full resolution crops have taken from original images at a range of ISO settings to show the overall image quality.

----



At ISO 80 the shot is a lot darker than usual, and there is visible noise in the mid-tone areas.

----



Not much different at ISO 100.

----



A little more noisy at ISO 200, but still not too bad.

----



At ISO 400 the noise is now getting to be a problem, with reduced fine detail and colour saturation.

----



Noise is significantly worse at ISO 800, with some nasty colour distortion.

----



Image quality is very poor at the maximum ISO 1600, with all shadow detail blurred out and lousy colour reproduction.

This is the full frame at ISO 1600.
