The Good Long zoom; Punchy colours; High quality movie mode; Built-in GPS.

The Bad 40x optical zoom doesn't stand up to particularly close scrutiny.

The Bottom Line The HX20V comes close to being the perfect traveller's camera, with a high resolution, long zoom and built-in geotagging features that put your pictures on the map. The auto modes are fast and accurate, consistently producing detail-packed, vivid results.

There are three things you want in a travel camera: a long zoom, decent resolution, and rugged good looks. With the HX20V, Sony's pretty much nailed each one.

This 18.2-megapixel pocket snapper (4896x3672 pixels) has a sturdy chassis without any flex or give, and a 20x optical zoom to the front. Add to that built-in GPS features, a flash that automatically folds away to keep it out of trouble when not in use and a decent movie mode, and it looks like a winner. To see whether that was indeed the case, I took it out for a spin.

The zoom

The HX20V feels as good as it looks. There's a chunky rubber grip at one end that helps you keep a sturdy hold, even with just one hand. This is important when you're using the maximum 20x optical zoom and, even more-so, the 40x option.

Sony's sales literature claims that the HX20V features '40x Clear Image Zoom' which, the company explains, 'doubles [the] 20x optical zoom range to an effective 40x, filling the frame with distant subjects while maintaining superb image quality'.

While I can't argue with the first half of that statement, the second half didn't chime with what I discovered in my tests.

The HX20V's zoom is extraordinary for so small a camera, and a real asset. If you're looking for a travel camera and don't want to carry a chunky body and several lenses then the optical zoom here gives you the equivalent of 25-500mm in a regular 35mm camera. At the widest end of that scale, it's perfect for landscapes, and at the longer end, it's great for telephoto shots of distant subjects.

The HX20V's zoom is certainly impressive, getting you very close to distant subjects.

If however you push it beyond the equivalent of 500mm, to the fullest extent of the 40x zoom (at which point the captured image effectively matches a 1000mm lens' field of view on a 35mm camera), you'll notice some interference when playing it back on your computer.

The seagull below was shot at the maximum 40x zoom. When viewed at less than life size the result is impressive, as can be seen from the zoomed out frame. Zoom in to 100 per cent however, as shown in the cropped sample, and the image is dappled and unsharp.

This frame was shot at 40x zoom, and while it looks good when viewed full screen, zooming to 100 per cent reveals dappling (click image to enlarge).

Fortunately this won't be an issue if you want to publish your images without cropping into them on a photo-sharing site such as Flickr. Similarly the effect won't be particularly noticeable in photos printed using an online printing service, where the resolution probably won't be sufficient to reveal this lack of clarity. Do bear it in mind though if you intend to crop just a portion of a 40x-zoomed image for use later on.

At the maximum optical zoom of 20x, the lens is impressively bright with a maximum aperture of f/5.8. Pulling back to full telephoto widens this to f/3.2.


If you're happy to leave it up to the camera to select the best combination of aperture, sensitivity and other settings, there are 15 scene modes to choose from. Between them, these modes cover regular scenarios such as fireworks and snow, alongside less common options like backlight correction HDR, soft skin and anti-motion blur.

The mode selection wheel gives you direct access to two auto modes -- intelligent and superior -- the former of which sets the best exposure, while the latter adds in blur and noise reduction. I performed my tests using the former -- intelligent auto -- to emulate most end users' experiences.

In this mode it consistently produced bright, evenly-exposed images in all lighting conditions.

The HX20V's mode selection dial includes not one but two auto modes.

The rear display is home to the usual indicators, such as flash, for the selected mode, to which you can add useful shooting data, including a level to keep your horizons straight and a histogram to warn of over- or under-exposure.

The cottage, below, is characterised by the three colours to which digital cameras are most responsive: green (foliage), blue (sky) and red (tiles and letter box). The HX20V has recognised a broad range of tones in each of these colours, with plenty of details in the foliage and smooth, accurate fades in the sky where the light cloud cover affects the visibility of the blue.

A very pleasing result from the HX20V here, with an image that plays to the strength of digital cameras (click image to enlarge).

There is also evidence however of minor chromatic aberration. This manifests itself as a turquoise or pink fringe on the edge of sharp contrasts. It is caused by the lens failing to precisely focus each of the wavelengths of light in the visible spectrum in sync with each other at the point where they reach the sensor. It's most often evident in the corners of the frame, as is the case here, where it is manifested as a pink halo on the pruned branches in the upper right corner.
