Panasonic Lumix DMC-GF2 - 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.

At ISO100 and all is well with the GF2's performance.

----


Same shot at ISO200 and similarly no image noise to report.
----


We're at ISO400 and some very subtle image noise is creeping in.
----


ISO800 and there's noise, but again hardly at a noticeable level.
----


Stop at ISO1600 if you want to avoid the noise levels appearing incrementally worse.
----


...And looking distinctly gritty in appearance at ISO3200.
----


So we'd recommend avoiding ISO6400 entirely, unless you do want a sandpaper effect.
