Fujifilm FinePix Z20fd - 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 is a full-frame image at the minimum sensitivity of 64 ISO. That E-Type is supposed to be red, not pink.

----



Even at minimum sensitivity there is visible colour noise in the dark green areas.

----



Increased noise reduction at 100 ISO has reduced colour noise slightly, improving the image quality.

----



At 200 ISO noise is starting to invade the red channel.

----



Increased noise at 400 ISO, and a noticeable loss of fine detail.

----



Heavy noise reduction at 800 ISO has reduced detail still further.

----



I've seen worse at 1600 ISO, but not often.

----



This is the full frame at 1600 ISO.
