Olympus Pen E-P1 - 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 pictures were taken indoors using reflected natural light

This is the full frame at 100 ISO. ISO settings at 1/3EV intervals are available on the E-P1, but the the sake of brevity I've only listed the full-EV settings.

----



At 100 ISO the image is pretty clean, although compare this with the Panasonic LX3, which has a 1/1.63-inch 10.1MP sensor.

----



Already at 200 ISO there is a faint dusting of image noise, and a trace of colour mottling in the green area.

----



More mid-tone noise at 400 ISO.

----



Detail is fading out at 800 ISO.

----



Noise is becoming a real problem at 1600 ISO.

----



Colour saturation is starting to fade out at 3200 ISO.

----



Image quality is pretty poor at 6400 ISO.

This is the full frame at 6400 ISO.
