Panasonic Lumix DMC-FX550 - Test Shots - ISO Performance

By Cliff Smith



Our Score:


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 ISO test images are shot indoors using reflected natural light for maximum consistency.


This is the full frame at the minimum ISO setting.


The image is clean and sharp at 80 ISO, with no visible noise.


No real difference at 100 ISO.


Quality is still good at 200 ISO.


There is visible noise at 400 ISO, but overall quality is still good.


Significantly more noise is visible at 800 ISO, but colour gradients are still relatively smooth.


1600 ISO is looking a bit ropey.


This is the full frame at the maximum ISO setting.

Bought my FX500 after the TR review and have been very pleased with it. Recently I got the instruction book out again as I realised I had slipped into using only i-Auto and had no idea about the rest or what i-Auto was deciding for me! Now, I can use all the bits again :) It is a very versatile & well built camera that can do quick snapshots or the more arty stuff whilst fitting a pocket/belt pouch.

Had an FX500 for 18 months or so. Was generally pleased with it, but somehow dust has got into lens / sensor (despite being carefully looked after) with no obvious way of cleaning it.

The "Exeter cathedral" picture it doesn't look very sharp...
