Some Olympus users might have been expecting the E-520 to incorporate a tilt-and-twist LCD screen and perhaps an updated autofocus system to replace the three-point design on the E-510.

Sadly neither of these made it through to the final design, which may disappoint some people who were hoping that the E-520 would havebeen a bargain-priced consumer version of the E-3.

Upgraded camera design

However, there's really no need to be disappointed. The twisty screen may not be there, but there are some interesting developments. First off, the sensor in the E-520 is a similar type to the professional chip used in the E-3.

It boasts a greater dynamic range than the E-510 and that's something we can confirm. Many of our test shots showed how the E-520 can really hang onto those highlights while still bringing out plenty of shadow detail.

The autofocus system has also been upgraded for better performance when shooting in Live View mode. There's still the normal 3-point TTL phase-detection mode when using the viewfinder, but for Live View there's a new 11-point contrast-detection system, which includes a face detection feature. It works well, although it's not as fast as the hybrid Live View focus on the Sony

A-300 series, so there's still a bit of a lag. However, it's an improvement on the old mirror-flapping faff that most Live View systems employ and that face detection feature really does work.

Cosmetic improvements

So, the E-520 has an upgraded focus mechanism and a better sensor, albeit with the same number of megapixels. It's not a lot to write home about so surely there must be something else?

Well, if you dig a bit deeper there are a few more tweaks but this is essentially a minor face lift, designed to keep the E-series ticking over in an ever-more competitive market.

There have been one or two cosmetic changes, including some smart black buttons and a much-improved mode dial and thumbwheel. Earlier models in the series had rather tacky-looking grey buttons and chunky Lego-style dials that cheapened the look of what was a very capable camera.

Olympus has fixed this and the E-520 looks every bit as smart as the old OM series of SLRs that partly inspired the current Olympus digital line-up.

Superb kit lens

All Olympus DSLRs use the Four-Thirds image-sensor format. This is less rectangular than the APS-C sensor that most other manufacturers use and it's also smaller.

On the one hand, a smaller sensor can mean a smaller camera and a smaller lens design. On the other hand, it also means there's an increase in the pixel density and that can translate into higher ISO noise levels.

And, true enough, if you pixel peep long and hard at the images from a Four-Thirds sensor you may notice slightly higher noise levels, but the E-520 does a really good job of keeping them under control.

When you print out the image you realise that extra noise doesn't add up to much. The glorious Olympus colours and superb kit lens make this a compelling option for a first DSLR.

Impressive build quality

The general build quality of the E-520 is superb. The plastic body is beautifully constructed and all the switchgear is top rate. The camera fits snugly in the hand and the ridged grip to the front lends a reassuring solidity to the package.

At the rear there's a 2.7-inch HyperCrystal II LCD screen. With 230,000 dots, it's not an ultra-high-resolution screen, but it's more than ample for reviewing shots and the quick zooming review feature using the thumbwheel control is much easier than some long-winded alternatives.
