Canon PowerShot A470 - 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.


This is the full frame at 80 ISO.


At the minimum sensitivity setting the image quality is very good, with little sign of noise.


Almost identical results at 100 ISO.


Noise is starting to creep in at 200 ISO, but overall quality remains good.


At 400 ISO noise is plainly visible, but overall colour rendition is still pretty good.


A dramatic reduction in quality at 800 ISO with a lot of image noise.


As usual the image quality at 1600 ISO is terrible.


This is the full frame at maximum ISO.

I think it's worth to notice that A470 is worse than its predecesor A460 from the optical standpoint. Zoom is actually 3,6x instead of 4x (38-132mm at A470 compared to 32-158mm at A460) while aperture starts at 3 (2.8 at A460).

We had two A460's fail 'just' outside the warranty period - the processor failed in both cases. Cannon were great and replaced both with A470's - I much prefer the A460. Not having an optical viewfinder is a step backwards. I've just purchased the G7 (fabulous!) and so had arranged to sell my A470 to my sisters, but now they've seen the Pentax S10...I've no hope. It'll cost them double but they just don't want the bulk of the A470. Anyone want to buy a camera?

I bought this Canon Digital camera for my 16 year old son to take it on his school trips after I checked various reviews on the internet including the http://best-digital-cameras... His previous Sony camera from lasted barely 8 months and took really mediocre photos. This Canon camera however is amazing! The pictures are very sharp, perfectly exposed and this Canon Camera is totally simple to use.

It seems that the menus are really designed for ordinary people, very easy to understand!. Son appreciated that very much.

The conclusion is that he had 24 hours to learn how to use this digital camera and then spent a week in New York with his class. The photos were great and his total camera experience was excellent. And one more important thing, I didn't break the bank for the purchase it!

Also worth noting this PowerShot does not include the stitch assist mode for taking images to stitched into a panorama on your PC or Mac which I consider to be quite handy.

Worth mentioning too the follow ups to this model-the A490/490/495 have a 3.3x lens instead of 3.4x (38-122mm on the follow up models compared to 38-132mm on the A470).

I agree with the use of the center button to zoom in or out to be quite couteractive.
