To compare real-life performance when zoomed-out, we shot this scene with the Canon IXUS 310 HS / ELPH 500 HS, Sony Cyber-shot TX10 and Panasonic Lumix FX77 / FX78 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 on each camera. The Canon and Panansonic were set to 100 ISO and the Sony to 125 ISO.

3 IXUS 310 / ELPH 500 HS Sample images

The image above was taken with the Canon with its lens at 4.3mm (24mm equivalent). The camera metered 1/400 at f2.8 and 100 ISO. The original image measured 3.68MB. The crops are taken from the areas marked with red rectangles and presented here at 100%.

Overall the image from the Canon IXUS 310 HS / ELPH 500 HS looks crisp, clear and nicely detailed. In these cloudy bright conditions the exposure is accurate resulting in good tonal detail everywhere from the shadows to the white walls. The white balance is good and the colours are vivid and natural looking.

The crops back up the initial impression gained from the whole picture. Generally detail is good with very minimal noise in evidence. There's a slight halo on the horizon where the hill meets the sky which is a result of digital processing, quite possibly a JPEG compression artifact. I can't find anything to fault in the second crop, fine detail is well resolved and you can clearly see the lighhouse despite the atmospheric haze.

In the third crop from the frame edge there's a little bit of colour fringing caused by chromatic aberration but the image detail is otherwise pretty good. The fourth crop from the middle of the frame is, again, hard to fault; the banner text is readable and fine detail is crisp with good edge definition.

Compared with the 16.2 Megapixel Sony Cyber-shot TX10 there's no doubt that the 12.1 Megapixel sensor of the IXUS 310 HS / ELPH 500 HS produces superior results. The Cyber-shot TX10 crops are generally softer with less of the fine detail picked out. The difference is most pronounced in the first and third crops, with the window crop looking clumpy by comparison with the IXUS 310 HS / ELPH 500 HS, though lacking the colour fringing problem. Overall, the Cyber-shot results are impressive for a 16 Megapixel model, but no match for the IXUS.

Crops from the 12 Megapixel Panasonic Lumix FX77 / FX78 look soft by comparison. The FX77 / FX78 overexposed the shot marginally, which isn't helping, but even the crops from closer to the centre of the frame look soft and lacking in detail compared with the IXUS 310 HS / ELPH 500 HS. And like the IXUS, the Lumix also suffers from slight Chromatic aberration at the extreme edges of the frame.

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