To compare real-life performance when zoomed-out, we shot this scene with the Canon PowerShot SX230 HS, the Sony Cyber-shot HX9V and the Panasonic Lumix TZ20 / ZS10 within a few moments of each other using their best quality JPEG settings.

The lenses on each camera were set to approximately the same field of view and all three cameras were set to Program auto exposure mode.

The ISO sensitivity was manually set to the lowest available setting 100 ISO - on each camera.

The image above was taken with the Canon PowerShot SX230 HS with its lens at the widest available 5mm (28mm equivalent) setting. The camera metered 1/1250 at f4 and 100 ISO. The original image measured 3.57MB. The crops are taken from the areas marked with red rectangles and presented here at 100%.

First impressions on looking at these crops and the test image overall is that that the PowerShot SX230 HS produces good quality results in these bright sunny conditions. The image is well exposed has good detail throughout the tonal range is nice and contrasty and has vibrant natural colours.

Moving to the crops, the lens and sensor combination looks to be producing excellent detail, there is a small but noticeable degree of texture but it's slight and you can make out the fine detail in the grassy foreground of the first crop very well. The only thing worth noting is there's a slight halo along the top and left edge of the chapel wall, but you need to look very closely to spot it even at 100 percent view.

The second crop pretty much bears out what you can see in the first. There are a lot of high contrast edges in this crop, from the lighthouse in the distance to the houses in the middle ground and the SX230 HS does a good job of picking them out. The slight graininess is a little more obvious in this crop, but it's not obscuring image detail and I personally don't find it at all objectionable.

The third crop, taken from the edge of the frame, is less impressive, primarily because of the quite severe purple fringing. This isn't the only place it occurs in the image and in fact on the other side of the frame it's actually worse with a hard purple line running along contrasting edges. The PowerShot SX230 HS's lens is almost wide open here at f4, we switched to Manual exposure mode and made further tests at f5.6 and f8, but the problem persisted to the same degree. Neither is the Chromatic aberration confined to the widest focal length settings, we spotted the same problem in shots taken at the tele end of the zoom range. In the absence of a RAW mode, it looks like this is just something you'll have to live with.

Compared with the Sony Cybershot HX9V I was quite surprised to see less of a quality difference than I would have expected between 12.1 and 16.2 Megapixel models. In the first crop the Cyber-shot HX9V doesn't pick out the detail as clearly as the PowerShot SX230 HS, but compare the second row and there really isn't a great deal in it. The Cyber-shot doesn't suffer from chromatic aberration to anything like the same degree as the PowersShot SX230 HS and again in the fourth crop it's a very close call.

Compared with the Panasonic Lumix TZ20 / ZS10 the Canon PowerShot SX230 HS clearly has the advantage in terms of image quality. The crops from the Lumix TZ20 / ZS10 are uniformly noisier. The first crop simply looks a lot grainier, resulting in the loss of much of the finer detail. In the subsequent crops there's also some quite unpleasant clumping of pixels. By the final crop things are looking a little more balanced but overall the crops from the 14.1 Megapixel Lumix TZ20 / ZS10 can't match those from either the 12.1 Megapixel Canon PowerShot SX230 HS or the 16.2 Megapixel Sony Cyber-shot HX9V.

Now let's see how they compare at higher sensitivities in our High ISO Noise results.
