Senior Editor / Advice

I've been reviewing hardware and software, devising testing methodology and handed out buying advice for what seems like forever; I'm currently absorbed by computers and gaming hardware, but previously spent many years concentrating on cameras. I've also volunteered with a cat rescue for over 15 years doing adoptions, designing marketing materials, managing volunteers and, of course, photographing cats.

Canon PowerShot SX1 IS

The Good

Relatively fast; good HD video; raw file support.

The Bad

Big; quirky interface; some image artifacts.

The Bottom Line

A top megazoom option, the Canon PowerShot SX1 IS offers a 20x zoom lens and HD video, which you can't get in a similarly priced dSLR, and delivers more features and slightly better performance and photo quality than the cheaper SX10 IS.

Would you pay as much for a megazoom as you would for a dSLR? That's the question you need to answer before plunking down the same amount of cash for the Canon PowerShot SX1 as you would for the EOS Rebel XS or the Nikon D60 with their 18-55mm lenses. Packing some higher-end features over its brother, the SX10 IS, including a CMOS sensor (albeit the same 1/2.3-inch size and 10-megapixel resolution), 30fps 1080p HD movie capture, and support for raw files, the SX1 delivers slightly better performance and image quality as well.

Physically, it's almost identical to the SX10, including the same 20x 28-560mm equivalent lens. It's equally comfortable to hold and shoot, retaining perks like the articulated LCD and four AA-powered operation. It's a little heavier, 1.5 pounds, which makes it feel like a dSLR, but the big grip gives you plenty of holding room. A button to jump into review mode sits near the indented thumb rest on the back, joined by the exposure compensation and focus area selection buttons. Because the SX1's body is matte black plastic, rather than the reflective graphite of the SX10, the light blue labels are easier to see.

On the right side of the back is a dial concentric to a four-way navigation switch with the function button in the middle. Although I generally like the controls, the dial feels too mushy; like the SX10's, it doesn't respond appropriately, as if it needs to spin too far or not as far for any given operation. As a result, for example, I frequently overshot desired shutter speeds. It really feels like it needs better tactile feedback. The zoom switch didn't feel terribly exact, either. This is a typical problem with stepped zooms (these lenses don't really cover a continuous zoom range, instead stopping at a series of preset distances).

Of course, the flip-and-twistable LCD remains a user favorite, and the SX1's is a wide-aspect 2.8-inch model compared with the 4:3 aspect 2.5-incher on the SX10. Keep in mind that when you're shooting photos at full resolution in 4:3 aspect, the effective image size of the LCD is as if it were a 2.5-inch model. Canon does use the extra area on the sides for displaying some information. Unfortunately, the electronic viewfinder isn't particularly great. It updates slowly and looks pretty coarse.

More annoyingly, the camera lacks a dedicated toggle between the LCD and EVF. Instead, you have to cycle through the four display settings: low-info LCD, detailed LCD, low-info EVF, detailed EVF. That makes it nearly impossible to quickly jump back and forth. Similarly, though there's a dedicated movie record button, moving between capturing HD movies and standard 4:3 stills can get confusing. You have to press a button to toggle between the two aspect ratio modes, and the camera captures in whatever your indicated settings are for that aspect ratio: press button for 16:9, start movie record, stop movie record, press aspect button, press shutter for photos. It sounds simple, but I frequently forgot to toggle the aspect ratio back after shooting a movie, and ended up shooting lower-resolution, wide-aspect stills. And raw isn't available in 16:9 mode, which can complicate mistakes like that. You should be able to set a movie size and only have to worry about pressing record. A final annoyance: it remembers all your settings when you power off except the current metering mode. None of these seriously detract from the overall usability of the camera, but forgetful shooters (like me) or infrequent ones might find themselves having a few more settings accidents than they'd like.

Though a movie mode remains on the dial, it's become rather superfluous; in addition to the dedicated button, Canon integrated the movie resolution settings into the function menu along with the standard white balance, color adjustment, exposure bracketing, flash compensation, metering, and still size and quality controls.

Some of the more novel features include a Face Self-timer, which shoots a specified number of seconds after a face is detected, and a custom timer, which lets you also specify the number of shots to take (sort of a limited intervalometer, since you can only take up to 10 shots). As with the SX10, this camera introduces Canon's Servo AF, the company's AF tracking mode. With this camera, since the continuous shooting is so slow, I find the Servo AF has too much time to get confused, and since EVFs black out when a shot's taken, you can't verify that it's focusing on the right thing; I have lots of in-focus fences and out of focus people in my test shots. (And lest you suggest I should have used the Face Detect AF, that doesn't work unless you're shooting faces looking at you, not moving crowd shots.) I find the Servo AF less than useful since EVFs black out when a shot's taken so you can't verify that it's focusing on the right thing. The rest of the capabilities, for the most part, are the same as the competition. These include PASM, full auto, and a handful of scene modes; my favorites are a custom setting slot on the mode dial and 3.9-inch macro and zero(!)-inch Super Macro modes. (Need more details about the standard feature set? Check out the PDF manual.)

Overall, the SX1 delivers excellent performance, especially for a category notable for sluggish products. It wakes and shoots in 1.4 seconds, and under optimal focusing circumstances can lock and shoot in 0.4 second. Even under harder to focus, low-contrast conditions, it takes only 0.6 second. Shot-to-shot JPEGs typically take 2.8 seconds, and raw is even faster at 2 seconds. While its 2.9 frames-per-second burst can't beat the ultra-high-speed continuous shooting of models like the Sony Cyber-shot DSC-HX1 or the Casio Exilim EX-FH20, it's still very good for its class. And it can burst raw at about 1.5fps. My only caveat about the camera's performance is from a repeated, but unfortunately not repeatable, problem with the AF system I experienced, in which it would indicate focus had been locked even though the scene was completely out of focus.

Generally, photo quality tends to be the weakest aspect of megazooms, but so far the SX1 seems to deliver the best for its class. While its colors aren't quite as good as the SX10's--oranges, yellows, reds, and purples are slightly off, though you probably couldn't tell without a side-by-side comparison--it has a better tonal range with less contouring in shadow areas. It has a better noise profile, with lower noise at all ISO levels, and without the blue channel artifacts I noticed in the SX10's photos. However, as with most models at this level, detail becomes visibly degraded at ISO 400 and beyond. It's pretty sharp, but by the numbers it fares worse than the SX10 for sharpness; I attribute this to some visible haloing in the blue channel I saw in the test charts.

The camera retains the separated stereo mics of its ancestors and can zoom--pretty quietly--during recording. And the video quality is quite nice--relatively sharp and saturated, with fast refocusing and exposure adjustment--especially played back on a large TV.

Though it's as big as and priced like a cheap dSLR, the Canon PowerShot SX1 IS delivers similar performance plus a 20x zoom lens and HD video that those can't provide. And while it's relatively expensive for its class and has some interface quirks, as long as you don't need ultra-high-speed burst shooting, it's probably the best megazoom option we've tested thus far.
