Canon PowerShot A550 Overview

Review Date: 04/17/07
The Canon PowerShot A550, introduced January 18, 2007, falls within the point-and-shoot category. While not as compact or stylish as the PowerShot ELPH cameras, the A550 represents a solid value in photographic quality and performance, offering photographers a number of distinct advantages. The suggested retail price of the Canon PowerShot A550 is $199.99, some $50 less than its predecessor, the A530.
Key upgrades over the Canon A550's predecessor start with its higher resolution image sensor: 7.1 megapixels, up from 5 megapixels. The 2-inch LCD screen also edges out its 1.8-inch forerunner. To accommodate the larger file sizes generated by the greater resolution, the A550 is compatible with SDHC memory cards. The A550 is also more energy efficient. With rechargeable AA NiMH batteries, you can take up to 1,400 shots with the LCD off. That's a whopping 400 shots more than the Canon PowerShot A530!
The A550’s 4x zoom lens with a 35-140mm 35mm equivalency is a very attractive feature, easily besting the more common 3x zoom. And while many people prefer to simply leave the camera dial permanently on AUTO, this camera’s easy-to-set scene modes can help you shoot better.
With its high quality imaging, competent feature set, and under $200 price point, the Canon PowerShot A550 can more easily meet the needs of a very wide audience of photographers. For pros and advanced amateurs, it’s nice to have a pocket-sized alternative to a more bulky digital SLR. The price makes this camera an attractive entry for anyone who has been thinking about going digital. As a gift for teens, the Canon PowerShot A550 costs less than a standard Apple iPod. As I’ll describe below, the camera is not only easy to use, but highly intuitive.
Canon PowerShot A550 User Report
Interface. I prefer to keep things simple. So does the A550. Most people could learn to love the Canon PowerShot A550 without ever moving the dial from its green AUTO position. Just point and shoot, and the A550 will most often give you great results.
With a turn to M (manual) more options open up to you. Just press the Function button on the back to access options like EV adjustments, White balance settings, Color modes, Metering modes, and resolution and compression settings. You can also access more of the flash modes in this version of Manual mode, though you can't actually set the shutter speed or aperture.
If you'd like to bias the camera for a certain shooting situation, just turn the dial to one of the icons, like Portrait, Landscape, or Kids&Pets. These modes have been set up to pick settings that will make shooting in these situations easy. Set it to SCN on the dial to access five more Scene modes. About the only shooting mode that seemed to be missing was a stitch-assist mode to help in creating panoramic photographs, a feature that was available on the PowerShot A530. Face Detection, available on the A570 IS, is not available here either. Another notable feature missing is the once-novel, but now trite MyCamera menu, where you could set special sound effects to go with different actions. But a howling wolf for the Self Timer mode? That probably earned more grimaces than smiles, so I won't miss it.
Power it up. Start-up was quick, ready in 1.3 seconds according to our lab results. There's plenty of lag time between shots, at least the same 1.3 seconds as the startup delay, and a full discharge of the flash takes that lag time out to 10 seconds while the flash recharges. That's quite a bit higher than average. It does take a second for the lens to come out, but it's faster than past models. The zoom was reasonably fast, about right for this kind of camera.
As much as I like an optical finder, I used the Canon A550's LCD screen exclusively to frame shots. Since most settings are made via the Function menu and Main menu displayed on the LCD, it's easier to switch between adjusting settings and framing, rather than continuously taking the camera from my eye to make a change.
The Canon A550 offers an 86,000 pixel, 2.0-inch LCD. While larger than its predecessor, it’s noticeably smaller than many of the 2.5-inch and larger LCD screens on compact point-and-shoot cameras. While that's fairly low resolution, the screen is small enough that it's not noticeable. The screen seemed a bit washed out in bright sunlight but wasn't totally unusable.
9-point AiAF. Like all Canon digicams, the A550 uses Canon's excellent and fast 9-point AF. The camera looks at the scene and selects from nine areas of the frame to find what it thinks are the most important points. If you don't like its first selection, just half-press the shutter again and it will most often recalculate its selection. It's a great way to shoot, and is the default in the automatic modes.
I like to keep a grid display on the LCD screen to aid in composition and alignment. I use a grid in my 35mm SLR, too. It was easy enough to turn on the A550's grid just playing with the menu; you can even turn on a 3:2 mask to show what a 4x6 inch print will look like.
The optical viewfinder isn't terribly accurate, but it does help to compose in bright sunlight. Two LEDs are right next to the viewfinder, a feature once used in Canon's old SureShot line and the ELPH series as well. The upper LED blinks green during startup, image recording and image transfer but glows solid green when the camera is ready to shoot or connected properly to a computer. When you depress the shutter release partway the same LED blinks to tell you the flash is charging, and glows orange when the flash is charged and ready to fire. If the flash is set to off, the orange LED also serves as a warning that light is too low for a sharp photo. The lower yellow indicator lamp confirms focus in the macro mode setting.
The A550 is powered by a pair of AA batteries, which is great because you can power up around the world without worry. This outweighs the A550's bulkiness in comparison to some of Canon's Digital ELPH cameras; and there are folks who will buy nothing but AA-powered cameras. I used the LCD continuously instead of the smallish optical viewfinder, but rarely had to change a set of batteries during a full day of shooting. As a fringe benefit, the bulge for the AA batteries gives the A550 a nice little grip.
It took me a few days of shooting with the Canon PowerShot A550 to find the settings that let this point-and-shoot perform like a high-end camera. And the truth is, with 7.1 megapixel resolution, the A550's printed output looks like it could have come from a high-end camera.
ISO 800. High ISO isn't as high as some other similar cameras, but the results are very good. You can get away with printing an 11x14 from the A550, and it looks darn good. You can see some color noise at that size, but contrast and vibrance are very good still. Print at 8x10, and you won't notice that it's an ISO 800 shot unless you get out the loupe (a loupe is a magnifier; if anyone gets out a loupe, remind them what you paid for this fine little shooter). Even the skin tones look good from our indoor shot, once proper white balance is set.
Speaking of white balance, while Auto wasn't perfect with our indoor test target, it was darn close. As is often the case, Manual white balance was better.
Overall, images from the Canon A550 are excellent at all ISO settings, keeping with tradition for the A-series.
Appraisal. The Canon PowerShot A550 is a great basic digital camera whose images will make you feel like a pro. Canon's interface has evolved to a point of excellence, as well, with most of the features you'll find on Canon's more expensive digicams. The A550 is still a little slow, but in most measures it's faster than last year's A520 and A530. We love the 7.1 megapixel sensor, which delivers amazing images for the money; you might think they're amazing for even more money. We'd have to agree with you.
If you have just a little more money, you might consider the A570 IS, which gives you even more high-end features from the ELPH series in about the same form factor. But if you just want to keep it simple, the A550 is an excellent, can't-lose proposition.

As we've come to expect from Canon's A-series, the PowerShot A550 is a great little digicam. Fairly frill-free, the Canon A550 still takes great shots with its 7-megapixel sensor. It has a satisfying 4x zoom, and is quite easy to use. The A550's no-nonsense mode dial is backed up by a simple Function menu; and though you can dig deeper with the main menu, you'll find fewer settings there than on other Canon models. In my opinion, less is more when it comes to a camera meant for the mass-market. More options will only confuse and invite error. Still, the A550 can make 640x480 movies at 30 frames per second, so it's ready to do anything most consumer buyers will need; and everything it does is above par for the category. The A550's 9-point AiAF autofocus system is excellent for candid shooting, and its high ISO functions are actually useful, turning out images that make excellent 8x10 prints. Its 7-megapixel sensor makes pictures that can be printed at 13x19 inches, quite an achievement at this price point. Though it doesn't have the biggest LCD, it still has an optical viewfinder. Priced at under $200, the Canon PowerShot A550 is a real bargain. The only reason we didn't make it a Dave's Pick is because the Canon A560 offers a bigger LCD and Face Detection autofocus for only $15-20 more (at typical street prices), making the A560 a better choice in our opinion.
