The Good Impressive performance and image quality; optical image stabilization; face detection.

The Bad No manual exposure controls; no optical viewfinder.

The Bottom Line While the Canon PowerShot SD870 IS doesn't have an optical viewfinder or manual exposure controls, it captures beautiful images with its wide, 3.8x optical zoom lens and ranks among the top compact cameras we've seen.

Each fall a barrage of new cameras hits the market, anticipating the year-end holidays. This year's batch of Canons includes the PowerShot SD870 IS. From its model number, you might think that it's a follow-up to the SD850 IS, but with its wider-than-normal, 28mm-to-105mm, f/2.8-to-f/5.8, 3.8x optical zoom lens, it's really more of a successor to the SD800 IS. Aside from a step up to an 8.3-megapixel CCD sensor, a larger 3-inch, 230,000-pixel LCD, and Canon's new Digic III processor, there's not much different in the SD870 IS other than some nice cosmetic enhancements. Along with the new processor comes Canon's Advanced Face Detection, which can pick out up to nine faces in a frame and use the faces to set autofocus and exposure.

Possibly the saddest change with this new model is that Canon omitted an optical viewfinder from the SD870 IS. This was probably done to make room for the larger screen, but it's an unfortunate compromise. On the upside, Canon spruced up the look of the camera's back, making it almost identical to the back of the SD750. This includes the newer version of Canon's multicontroller pad. It's more responsive than the pad on the SD800 IS, and a raised ring around the edge gives it a better feel. Plus, when you rest your thumb in any particular direction on the pad, a graphic appears on the LCD to show you what you'd do if you press fully. This helps you to keep your eyes on the screen when you have to change a setting while shooting.

Probably the only real ergonomic flaw on the SD870 IS is that there's no convenient place to rest your thumb. So, while all the shooting controls can be accessed through buttons on the right side of the camera, one-handed shooting can be annoying as you're forced to put your thumb on top of the right edge of the LCD screen--thereby blocking some of what you're trying to frame in the picture. Though the camera's optical image stabilization (hence the IS in the name) should help keep things steady, you may welcome the use of a second hand, since the SD870 IS weighs in at a somewhat hefty 6.4 ounces, with the battery and an SD card installed.

As usual with Canon's Digital Elph cameras, you won't find any manual exposure controls. Instead you have to rely on the camera's exposure compensation if you want to tweak the camera's automatic exposure, or resort to one of the camera's 10 scene modes to handle out-of-the-ordinary shooting scenarios. Flash exposure compensation lets you control the output of the flash, so the flash doesn't overpower your subjects if you're too close--a nice touch that's not found in all compact cameras.
