Canon IXUS 860 IS

Summary

Our Score:

9

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 view of the minimum ISO setting.

----

At 80 ISO the image quality is pretty much perfect, with accurate colours, good detail and no noise at all.

----

Virtually no difference at 100 ISO.

----

There is a small amount of noise visible at 200 ISO, but not enough to worry about.

----

As usual with Canon cameras, the more damaging chromatic noise is well suppressed, leaving only a little grain-like luminance noise at 400 ISO.

----

Noise is a lot more noticeable at 800 ISO, but there is still a good level of detail and the shot is printable.

----

Image quality does break down somewhat at 1600 ISO, with visible colour distortion in the darker areas.

----

This is the full frame at 1600 ISO.

Bought this camera in January 2008. Always looked after it in the case and never dropped it. Had the lens fail on this camera 3 times and had it repaired 3 times. Could not get a replacement. Thought I was on a good wicket when I bought this camera, but obviously not.

Bought mine 1 year ago.It has developed serious focussing problems in all lighting conditions and I have returned it to my UK supplier under their 2-year warranty. It has been sent on to Canon for repair but I don't have much confidence that the repair will be permanent as I have read of other owners with the same problem. Have advised the supplier that if it fails again after repair I will be seeking a full refund or replacement with the later updated 870 is model. Will report back!

Bought in September 2008, and it has been faultless - a great little camera for travel. Good lens, tough body, small size, fast switch on. The capacity to do some basic manipulation of images (Vivid, Sepia etc) in-camera is fun.

Reporting back a year after the focus problems with my 860is and have to say that this gem of a compact has behaved perfectly ever since the repair. I have 2 other more versatile, but bulky, long-zoom cameras but this one lives permanently in my car ready for that once-only chance shot!
