Olympus X-915 - 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.

This the full frame at ISO64.

At ISO64 image quality is fair, but some noise is visible even at this setting.

A slight increase in noise and some softness to the image can be seen at ISO100.

Images at ISO200 aren't as smooth as some noise reduction is being applied. This results in less speckled noise, but some blotchiness is apparent and detail is reduced.

The colour blotches first seen at ISO200 are becoming more apparent and both colour accuracy and detail fall further.

Images are very gritty at ISO800 and ugly yellow/green blotches are quite distracting.

At the maximum ISO1600, images are very gritty loose colour accuracy and pretty much devoid of useful detail.

This is the full frame at ISO1600.
