The PowerShot SX230 HS is Canon's top compact megazoom featuring a 28mm-equivalent wide-angle lens with a 14x zoom. It's the same lens used in 2010's SX210 IS and the body is for the most the same, too. The major change is to the camera's imaging sensor; the SX210 had a 14-megapixel CCD while SX230 has a 12-megapixel back-illuminated CMOS. Without getting into the technical differences, what you need to know is that the new sensor produces better low-light photos and has faster shooting performance than that of its predecessor. Canon also built in a GPS receiver for geotagging your photos while you're shooting--a first for a PowerShot.
However, while its photos--and movies--are pretty great for its class, the SX230's shooting performance is a bit behind the competition. Its lens isn't as wide or as long as similarly sized models and Canon doesn't do as much as others with the GPS capabilities, either. Plus, everything about the design that was off with the SX210 is still off with the SX230. You'll have to decide if my issues are deal breakers for you, though, because it's otherwise a very good compact megazoom.

The SX230 HS has some of the best photo quality I've seen from a compact megazoom, particularly at higher ISOs. While photos do get softer and noisier above ISO 200--typical for point-and-shoots--ISO 400 and 800 are still very usable. The noise and noise reduction are well balanced so you still get very good color and detail at these higher sensitivities. Colors desaturate some at ISO 1600 and 3200, subjects look very soft, and detail is greatly diminished, but photos are still usable at small sizes for prints or on a computer screen. Basically, if you need to shoot in low light or want to freeze action, this camera is one of the best options in its class.
There is some asymmetrical distortion on the left side of lens visible at its widest position. When the lens is extended there is slight pincushion distortion, but it's barely discernible. Sharpness is very good and consistent from edge to edge and in the corners--pretty rare on a compact megazoom. The SX230 exhibits a high amount of fringing around high-contrast subjects. It's typical of compact cameras, but the amount is above average for its class, visible even when viewed at small sizes.
Color performance is a strong point with the SX230 HS. Everything turns out bright, well-saturated, and reasonably accurate. Exposure is generally good, though it really struggles with highlights, blowing them out every chance it gets. White balance is fairly accurate, too, but Auto goes warm indoors. You're better off selecting the appropriate preset for your lighting or using a custom setting.
Video quality is also excellent. It shoots in full HD, but it's at 24 frames per second. That's not ideal for shooting fast-moving subjects as you'll see some judder that's typical of the video from most compact cameras. The same goes for quickly panning the camera. Otherwise the results are impressive, even at its lower resolutions. The zoom lens does function while recording, but you will hear the movement in quiet scenes. There are stereo mics on front, but the left mic is too easily blocked if you're not paying attention to your hold on the camera.

Shooting options on the SX230 HS run the gamut from simple point-and-shoot options to full manual controls. The manual shooting options are better than most compact megazooms. You get semimanual and full manual control over shutter speed and apertures as well as manual focus with a safety for fine-tuning. Apertures include f3.1, f3.5, f4, f4.5, f5, f5.6, f6.3, f7.1, and f8. With the lens fully extended, you only get three settings, though: f5.9, f7.1, and f8. Shutter speeds can be set from 15 seconds to 1/3,200 second (1/2,500 is the fastest with the lens extended). There are options for setting color saturation, sharpness, and contrast, too, and the flash strength can be easily adjusted. A flash exposure lock, which adjusts flash output for what you're focused on, can quickly be activated as well; it functions well for keeping the flash from blowing out subjects.
If you just want to point and shoot, there's Canon's Smart Auto, which determines the appropriate settings based on the scene you're shooting. An Easy mode works similarly, but heavily limits settings. Frankly, the Smart Auto is easy enough and this spot should have gone to a custom mode. Canon also put on the mode dial three popular scene selections--Portrait, Landscape, and Kids & Pets--and a SCN choice for accessing other scene settings like Low Light, Beach, Foliage, Snow, Fireworks, and Panorama Stitch Assist. There's an Underwater option, but it's for use with an optional casing; the camera is not waterproof. Canon includes its Smart Shutter option to the Scene mode, too; this includes a smile-activated shutter release as well as Wink and Face Detection Self-timers. Wink allows you to set off the shutter simply by winking at the camera and the Face Detection option will wait till the camera detects a new face in front of the camera before it fires off a shot. Both work well.
