Summary

Our Score:

8

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 80 ISO.

----

Image quality at the lowest ISO setting is superb.

----

Not surprisingly image quality is unchanged at 100 ISO.

----

Still no trace of noise at 200 ISO.

----

There is a little luminance noise at 400 ISO, but it is barely noticeable.

----

Noise is a bit more prevalent at 800 ISO, but the image is still printable.

----

Some fine detail has been lost at 1600 ISO, but the overall image quality is still surprisingly good.

----

This is the full-frame image at the maximum ISO setting of 1600.

I am waiting for Canon to make a camera which will be a suitable replacement for my Powershot A620. Currently they make nothing that ticks all the right boxes.





Its quite simple. All I want is a tilt and swivel LCD and a reasonable battery indicator. The powershot I have, has a tendency to run the batteries down when its not being used. And when they do run out it gives you under 1 minute of warning before they give up completely..... which is absolutely ludicrous.





I have emailed them to ask if they have such a camera in their range. The reply i have says that they do either or, but not both. Until that day... I will wait.

Now the price is down to 𧵃.99 at Jessops the A720IS looks a very good buy for anyone wanted a bit more control than a simple P&S.

I only paid 𧴹.99 for mine at Jessops. Lacks the 28mm capability of my Canon Ixus 850 (pickpocketed in Cape Town) but zooms out to 200+mm. Bulkier too but otherwise it's great and a real bargain at that price.
