Canon Powershot A2000 IS | Digital Camera Review | Adjustments
Upon arrival of a Canon PowerShot A2000 IS test sample, it is tested in our DIWA Lab. The technical data of the rigorous tests are processed and translated into understandable data. Inside the lab, testing takes place in standardized circumstances. An environment in which cameras, both compact and system concepts, can be compared without a problem. Besides that, the Canon A2000 IS compact camera is extensively used in practice and evaluated as for operation and shooting in practice. This combination of lab tests and the testing in practice, results in a final conclusion that is carefully reviewed.

Colour reproduction & ISO range
The Canon A2000 IS produces true-to-nature colours with only slight saturation. During testing in the DIWA Lab, the color reproduction of the Canon A2000 IS was compared to the Gretag Macbeth Color Checker and shows only a marginal difference. In practice, the colors are fresh and natural. The result of the measurements over the entire ISO range from 80 up to 1600 inclusively is stable with hardly any shades. The extensive white balance offers possibilities for nearly all light sources, although the manual mode performs the best. Once manually set, there is hardly any color cast visible over the entire ISO range. If you leave it up to the white balance, you will only notice some color cast at incandescent light environments.

DIWA test lab - ISO differences
Striking results have come from the measurements for the actual ISO values. Since the DxO Analyzer version 3 entered our DIWA test lab, a test to measure the actual sensitivity of the image sensor over the entire ISO range is included. An average difference of 20 to 25% seems to be rule rather than exception and it is striking to see that the CCD sensor of the Canon A2000 IS is almost identical to the specified IOS values. An extremely good achievement.

Internal noise reduction on the Canon A2000 IS
An increase of the sensor resolution provides more image information, that bit is true, however, unwanted effects such as noise usually go hand in hand with it. How annoying this noise is, depends on several factors. One thing is the internal noise reduction of the camera; however, if this noise reduction is working too strongly, it causes the so-called 'smudge' effect with inevitable loss of detail. First of all, there is good news about the low ISO value, it performs well and provides a good noise-free picture. Unfortunately, soon after that, the signal/noise ratio drops drastically.

Even at ISO 400 we see an increase of noise and a stronger noise reduction which causes loss of details in the picture. Yet, in general the pictures turn out well enough to print. At ISO 800 there is visible noise and the image quality becomes poor.

Canon PowerShot A2000 IS - Dynamic range
The Canon PowerShot A2000 IS has a superb dynamic range, up to and including IOS 200, decreasing from sufficient to good at ISO 800. The most sensitive value of ISO 1600 performs poorly and wasn't really that useful anyway due to the high noise rate. The combination of signal/noise ratio quality and dynamic range shows a great performance of the Canon PowerShot A2000 IS in sufficient daylight; however, the high ISO values are a negative influence on its performance.

Blur at the edges in wide/angle and telephoto
When it comes to sharpness, the 6x optical zoom performs superbly with only some expected blur at the edges in wide-angle and slightly more in the telephoto area. In wide-angle, we find stronger distortion than we expected along the edges of the lens. The remaining focal lengths are distortion-free. This is in fact a good result from an excellent zoom lens.

Chromatic aberration & Vignetting
The zoom lens is not completely free of chromatic aberration, although not evidently visible. At wide-angle, chromatic aberration is slightly visible, yet not annoying. In the telephoto range, the zoom lens is in danger. It's on the edge of annoying chromatic aberration but we give the lens the benefit of the doubt. More so when we take the price/quality ratio of the camera into consideration. The same more or less goes for vignetting. The effect is slightly visible in wide-angle, yet providing a fine result. From a quality viewpoint, the 6x optical zoom of the Canon PowerShot A2000 IS camera performs superbly.
