Powering up in an instant, with the broadest focal range of any mega zoom on the market we can forgive the SX30 IS the odd soft shot when attempting to shoot handheld at extreme telephoto, whereon the framing does tend to float around a bit before your very eyes and it’s difficult to get composition exactly as you want it without first having two or three goes.

With roughly that number of attempts we were able to achieve commendably crisp results when shooting handheld at maximum zoom in broad daylight however, as our test shots indicate. Unsurprisingly when faced with busy scenes the camera has trouble deciding on whether it should be focusing on the background or your intended subject just in front of it, but again a couple of attempts and we got what we were after.

It helps that the camera is responsive. The zoom travels through its expansive range in a relatively swift three to four seconds. There is a low mechanical grinding noise as it does so, but this isn’t off-putting, especially when shooting outdoors when you’re surrounded by potentially distracting sounds anyway.

Although the SX30 IS’ LCD screen may be slightly smaller than we expected at 2.7-inches, when 3-inches and above is the norm, plus its resolution is lower than we would have liked, it does the job. There’s always the alternative of the 202k dot resolution electronic viewfinder just above, but with the LCD having the further advantage of not only being bigger but providing the ability to swivel and tilt as well – as on Canon’s equally recent EOS 60D DSLR – we didn’t find ourselves using the EVF all that often.

Overall when it comes to results from the SX30 IS, any grumbles we have to level at it are the usual ones. Images appear a little flat and distinctly two dimensional straight out of the camera, so require some modest tweaking for brightness and contrast at the image editing stage. Plus there is some slight (but not overly pronounced) loss of definition towards the corners of the frame when shooting at maximum wideangle. Neither are unexpected but we feel the need to be picky when this is a camera costing almost as much as a DSLR which would over much sharper and realistic results overall.

You’ll undoubtedly only be considering this camera if the versatility of an extremely broad focal range is highest on your tick list of wants. Though it doesn’t boast quite the same reach – but almost – we actually prefer the build quality and even chunkier glass offered by Fuji’s FinePix HS10, which overall we feel offers slightly better value for money too.

That said, there is no denying that the SX30 IS proves to be a versatile tool, allowing any number of framing and compositional combinations with its one camera, one lens set up. It’s not only easy to use, but as our test shots show, it’s also reasonably easy to achieve decent results with it too. It has obvious appeal to families, who perhaps want better pictures than their pocket snapper will deliver, but are put off by the perceived learning curve of a digital SLR or compact system camera.

The negatives are that it costs as much as an entry level DSLR equipped with a standard kit lens, has a slight plastic-y feel that even Canon starter DSLRs have, and images tend to lack contrast and necessary visual ‘oomph’ straight out of the camera, so require a couple of minutes of tweaking to get them looking their best. If you can live with that and really do need a ‘big one’, then the SX30 IS could prove to be a solid choice for any number of applications.

“A selection of images taken at the camera’s incremental light sensitivity settings, using only available daylight.”

—-

Full frame at ISO80 – starting out lower than most – and, unsurprisingly, all is well with the IXUS SX30 IS’s performance

—-

Same shot at ISO100 and no discernible difference

—-

Same lack of noise to report at ISO200, so the camera is performing as we would expect at this level

—-

We’re at ISO400, usually the setting at which noise begins to creep in on if we’re unlucky. Here we’re just starting to lose definition in the shadow areas upon close inspection, but only very slightly so.

—-

Noise is becoming more pronounced when examining shadow detail at ISO800, but overall the image is still fairly clean

—-

At ISO1600 we’re noticing even more softness and graining but this option has still provided a perfectly usable result, suggesting Canon was perhaps being conservative in capping its ISO here

—-

…And so we’ve tried shooting our test image with Low Light mode selected, which effects an image drop to three megapixels. Here the camera has itself chosen a setting which equates to ISO500, so again, no apparent noise.

The full frame in Low light mode.

“A more general selection of unadjusted test shots are revealed on this page and next to act as an evaluation of the PowerShot SX30 IS in a variety of shooting conditions.”

—-

This wideangle shot reveals ever so subtly converging verticals, but otherwise detailing is good, plus colours and exposure are more or less spot on.

”’Full res crop”’

—-

By contrast a handheld shot from the same vantage point utilising the telephoto end of the zoom to pull the statue out from its (attractively defocused) background. Again a good level of detail, but a slightly flat image that could be given further definition with a judicious tweaking of brightness and contrast in Photoshop.

—-

Another extreme telephoto shot made all the more difficult by moving subjects and overcast conditions. But again, a degree of softness is to be expected shooting handheld at maximum zoom. We’ve lost a bit of highlight detail, but nothing we can’t live with.

—-

By contrast again, this is a wideangle macro/close up shot. The PowerShot SX30 IS allows photography as close as 0cm from your subject. Can’t get much better than that! Again, some subtle tweaks at the image editing stage would really bring out those colours further and correct for a slightly blu-ish daylight colour cast

“Here are some general test shots taken with the SX30 IS to give an idea of performance ability when it comes to image quality, dynamic range, colour rendition and the focal range of the respective optics.”

—-

This crop of an image taken at maximum telephoto zoom setting in the golden light of a late afternoon shows the richness of colour rendition achievable with the SX30 IS when conditions are in the photographer’s favour

—-

And here’s an image taken with the Canon’s miniature digital effect filter applied, which reduces the area of the image in focus to a central narrow band. You’ll also notice, if comparing this with the colours of our ISO test shots, that the overall image has been automatically warmed by the camera

—-

Generally, although we’re happy with the SX30 IS default treatment of colours, images can be a bit flat and lacking in contrast straight out of the camera, as we’ve noted. So here we’ve included an image of our wall mural before, and then after some brief Photoshop adjustment
