The bridge camera sector of the market is one that continues to grow and expand, despite the relative downturn in the rest of the compact camera arena.

These cameras are DSLR style in shape and sometimes size, but find themselves within the compact camera area of the market because of the size of their sensor, which is generally the same as standard compact cameras. In addition, the lens is fixed rather than interchangeable.

Canon SX520HS

The Canon SX510 HS has been around for some time, and with the increase in competition from Sony, Panasonic and Samsung, it's not surprising to see Canon introducing new models in this sector.

In terms of its zoom range, although 42x is long, by some standards, it's actually fairly modest. As it stands, 62x optical zoom is the current market leader. However, with a 24mm wide angle lens, that gives you an impressive reach of 1008mm at the telephoto end of the optic.

Canon has also included its ZoomPlus technology for this camera, which is its type of digital zoom. That boosts the zoom range up to 84x, and works by rebuilding the pixel count up to the same resolution as those taken using the optical zoom.

The SX510HS uses a 16 million pixel 1/2.3 inch CCD sensor, which is a fairly unusual choice in these times when most manufacturers are using CMOS sensors. Traditionally, CMOS sensors perform better, so it will be interesting to assess the image quality of the camera when we get a full sample in for review. The good thing about CCD sensors is that they tend to keep a camera's price down.

Designed to be a slightly more advanced product than other bridge cameras in Canon's line-up, along with fully automatic modes, you can also shoot in manual and semi-automatic modes (such as aperture priority and shutter priority) with the SX510HS. The ability to shoot in raw format is not offered, though.

The camera uses a Digic 4+ processor, and while this isn't Canon's most recent processor, it is claimed that it is 60% quicker at high ISOs and 30% quicker at focusing and processing than a standard Digic 4 processor, which is what the SX510 used.

Other interesting features include Hybrid Auto, which takes a two second clip of video along with every picture (when shooting in auto mode) for a highlights video at the end of the day, and Creative Shot, which takes five images with a digital filter applied to it.

The camera's sensitivity runs from ISO 100 – 3200, and Zoom Framing Assist is also included – this helps when framing an image with the lens zoomed out to full telephoto zoom.

Build Quality and Handling

A quick glance at the SX520 may lead you to believe that the camera is a small DSLR, being reasonably similar in size to something like the Canon EOS 100D. It is likely to be the large zoom lens which causes this fairly large size.

There's a chunky grip which feels very comfortable in the hand, with a ridge on the grip for your finger to make it sit very nicely. On the top of the grip is a zoom switch for extending the lens – this makes it more similar in usability to a standard compact camera than a DSLR which would usually require you to zoom via the lens itself.

Also found on this grip is a scrolling dial, similar to those you might find on a DSLR, which can be used for changing various settings depending on the shooting mode you're in. For instance, while in aperture priority, you'd use it to control aperture. Anyone who has been familiar with Canon's range of EOS DSLRs will feel very at home here.

You'll also find a mode dial, which allows you to quickly change between different exposure modes, such as manual, automatic or aperture priority.

The button layout on the back of the camera is also very reminiscent of Canon's DSLR range. You'll find a four way navigational pad, with each of the buttons assigned to a different function. For instance, up accesses sensitivity (ISO), left accesses focusing mode, down accesses display options, and right accesses flash options.

A dedicated button is also available for changing the drive mode. The other two buttons on the back are a playback button and a menu button. On the side of the lens is the frame assist button. Hold this button down while zooming into a subject and the lens will retract, allowing you to find the subject again. Once you've found it, release the button and the lens will return to the former zoom point.

Performance

It is of course hard to give a full assessment of performance at this stage in the release cycle, but generally I find Canon compact cameras to be good performers.

We were fairly impressed by the SX510HS, so I see no reason why this shouldn't be an improvement over its predecessor. That said, however, with a lot of competition in the bridge camera section, it'll be interesting to see how images from this camera compare with those from other manufacturers.

Early Verdict

It's good to see Canon updating the 510HS as it's been a while, however, arguably the company has played it pretty safe here.

A 42x optical zoom is a very good range, but it's not market leading. There's also nothing particularly exciting, such as Wi-Fi or a touchscreen to use here.

On the other hand, it also has an RRP with a more reasonable price than some of the competition, and that is what's likely to make it stand out from the crowd – value.

Look out for a full review of the Canon PowerShot SX520 soon.
