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 pictures were taken indoors using shaded natural light.


This is the full frame at minimum ISO.


Image quality at 80 ISO is pretty good.


There is a trace of colour mottling even at 100 ISO.


Noise is clearly visible at 200 ISO.


Noise reduction has removed some of the chromatic noise at 400 ISO, but the image still have luminance noise.


Noise reduction has reduce image quality at 800 ISO.


Image quality is quite poor at the maximum 1600 ISO.


This is the full frame at 1600 ISO.

Was giving 7/10 it for image quality another April Fool joke?

Good to read a review that takes into account the price and the target market of the camera. The mark-down on build quality is well-deserved: there is no excuse for making plastic mouldings that do not meet and hold neatly and firmly. Canon have made a minuscule and inappropriate "economy" on that one, even at this price point.

"There are much better cameras available for just £20 more"

What are they?
I have the impression that you have taken this test a mistake and you are not able to evaluate it through. You have made ​​some macro photography? You have compared the series of the same Canon 2000 and 3000? The A490 has superb image quality and superior digital cameras that constantly 4 -5 times as much. I'm sorry, but if you make these comparisons do not mind that it is a camera for 50 euros, you can not judge it. For me it is a 10/10
