Canon updated 2009's PowerShot A480 by splitting it into two models: the A490 and A495. The PowerShot A490 is AU$20 less expensive than the A495, but it's available in silver only; it has a 5-point Face AiAF autofocus system instead of the A495's 9-point; it has neither a Face Self-Timer (explained later in this review) nor Canon's two, new creative shooting modes — Super Vivid and Poster Effect; and it uses 13 scene settings for its Smart Auto mode, whereas the A495 uses 18.
Regardless of those differences, both cameras turn out great photos for their budget price tags (though the A495 seemed to get negligibly better results in Auto mode). The biggest downside is that they aren't remotely fast when it comes to shooting performance, and shot-to-shot times are particularly long. Still, if you're strapped for cash and want a pocket camera, both are worth the money for their photos alone. The extra shooting modes on the A495 are nice, too, but if you don't need them or any of the other things mentioned above, save AU$20 and get the A490.
Design and features
Available only in silver with black accents, the A490 is chubby, but still reasonably compact. It's not very wide or tall, but is more than an inch thick, so though it'll fit in a pants pocket, it might be a tight squeeze. From the front, the camera looks reasonably stylish with nice rounded corners. Unlike the A480, the buttons don't feel cheap and are clearly marked in white on black. In fact, the overall build seems improved. Plus, Canon kept the controls straightforward and simple, and the menu systems are likewise uncomplicated.
On top are the power and shutter-release buttons, with the remaining controls on back to the right of the LCD. At the top is a zoom rocker, below which are a button for playback, a four-way control pad with select button, and the shooting mode and Menu buttons. The Menu button pulls up two tabs of general settings whereas the select button (labeled Func. Set) opens shooting mode-specific options. Overall, it's easy to control and should be simple enough for beginners out of the box.
The lens is narrow, at a 35mm-equivalent of 37mm, and it has an optical zoom of 3.3x, which is standard for cameras in its class. The LCD, despite its decent size, is fairly low resolution and even though it gets fairly bright, it can still be tough to see in direct sunlight.
This model is powered by AA-size batteries — something many people find convenient. However, you'll only get about 150 shots out of the A490 before they'll need to be replaced. Getting two NiMH AA-size batteries should more than double your shot count, though.
The PowerShot A495 predictably doesn't have a lot of shooting options, and the A490 has even fewer. The most complicated it gets is in Program, which gives you options for white balance, focus, metering, ISO, and colour effects. Don't want to touch any of those things? Canon's Smart Auto (simply called Auto now) is very reliable at picking the appropriate settings based on 13 different scene types. Or you can choose from 1 of 11 special scene modes, like Fireworks, Long Shutter, Foliage, or Kids & Pets. Canon renamed its High ISO mode "Low Light" to alleviate confusion, but it's otherwise the same, capturing 2-megapixel shots at ISOs from 500 to 3,200. If you like taking a lot of close-up macro shots, the A490 is a great option for the money. You can get very close — down to 1cm — and the autofocus seems improved from the A480, which struggled to properly focus.
The Movie mode is VGA only, with no use of the optical zoom while recording. The video quality is good — on par with a standard-definition pocket video camera. It's fine for a quick clip to post online, but not much else.
Performance
Performance, though not dreadfully slow, is still pokey. It takes 2 seconds for the camera to go from off to first shot captured. Shutter lag is a little long in bright lighting conditions: 0.6 second from pressing the release to capture. In dim lighting, the shutter lag is 1 second. Shot-to-shot times are mediocre at 2.9 seconds without flash, jumping to a lengthy 7.1 seconds with it on. Lastly, its continuous shooting time is only 0.6 frames per second. Basically, if you're hoping to catch shots of an active toddler, an athlete in action, or fast-moving pet, this camera isn't a good option.

Image quality
The photo quality from the A490 is excellent for the money and is actually better than some more expensive models. Of course, it produces the best results below ISO 200 — sharp with plenty of fine detail. But even at ISO 800, noise and noise suppression are well balanced, making 4x6-inch prints possible. When photos are viewed at 100 percent, you will see noise, particularly in darker areas of photos. However, it's nothing that would keep me from recommending this model.

The lens has minor barrel distortion at its widest position and no discernable pincushion distortion when zoomed out. Center sharpness is very good, though there was some softness in the extreme corners. The amount of purple fringing in high-contrast areas is average for its class: visible when photos are viewed at full size, but not likely to destroy a photo.

Colours are great from the A490. Blues are a touch lighter than they should be according to our tests, but others are close to accurate, and are bright and pleasing. Exposure is generally very good, though clipped highlights aren't out of the question.
Conclusion
Canon's PowerShot A3000 IS is AU$20 more than the A495 and has a better lens, a rechargeable battery, and image stabilisation, but honestly, we'd rather save the money and get the A495 or the A490. The shooting performance was comparable, but the photo quality was better from the two less expensive models in our tests.
