The Good Fast Live View AF and single-shot performance; tiltable LCD; dual card slots; relatively simple, straightforward operation; built-in wireless flash and image stabilization; helpful SteadyShot indicator.

The Bad Smallish grip; middling viewfinder; default settings produce suboptimal photos.

The Bottom Line The Sony Alpha DSLR-A330 is a solid entry-level dSLR that will surely have its fans, but unless you really want Live View, its cheaper sibling, the A230, is a better deal.

Editors' Top Picks

A modest update over its predecessor, the Sony Alpha DSLR-A300, the Alpha DSLR-A330 offers the same essential feature set in a redesigned body with sufficient quality and performance-enhancing firmware tweaks to merit the term "upgrade." And like its predecessor, the result is a generally solid, if not stellar, entry-level dSLR option.

The A330 is nearly identical to its cheaper sibling, the A230. The only differences are in the viewfinder--the A230's has a much higher magnification, making it more comfortable to use--and in their LCDs. The LCDs are the same 2.7-inch model, but the A330's can be tilted up perpendicular to the body or down at a 55 degree angle. The A330 also offers Live View shooting, while the A230 doesn't. As they're essentially the same camera, they should deliver the same image quality and performance. Sony also offers an identical but higher-resolution version of the A330, the 14-megapixel A380.

You can get the A330 in one of two color schemes, black and metallic gray and brown and metallic copper--the brown version won't be available until the fall, though. Each comes in two kits: one with an 18-55mm lens (black, brown) and a dual-lens kit with that lens plus a 55-200mm model (black, brown). At the moment there's no body-only version of the A330, but one could possibly surface later in its life cycle. As with all Sony dSLRs, you should be able to use any Minolta A mount lens with the camera.

Most of the redesign works for the better, though I do have a couple of quibbles. It's lighter, though it still seems to fall in the middle of the sub-$1,000 dSLR herd for size and weight. The new grip design doesn't work for me, however. It's only three-quarters the height of the body and doesn't feel nearly as secure as full-height grips. I do like the rubberized texture that covers it and the left side of the body, though.

The mode dial, which provides the usual access to a handful of scene program modes and the typical manual, semimanual, and full automatic exposure modes, sits to the left of the viewfinder, while a large Live View/optical viewfinder toggle switch sits to its right. Also on the top right is a cryptic button for the Smart Teleconverter, a 1.4x or 2x digital zoom that produces results identical to cropping and only works in Live View mode. On a ledge behind it is the exposure compensation button; I don't particularly like its position or feel, though. It's hard to feel, and you have to move your whole hand to reach it with your thumb, and I think that will discourage people from using it.

Sony provides both an SD and Memory Stick Pro Duo slot in all its entry-level models, with a manual switch to choose between them, so you don't have to commit to the less popular proprietary format. In an unusual design, the slots and the USB and miniHDMI connectors sit under a sliding door on the left side of the camera instead of the more common right side. (The half-height grip probably necessitated this.) It doesn't seem to affect usability, however.

The back controls are pretty typical for a modern dSLR and will be instantly recognizable to advanced point-and-shoot users. A four-way navigation switch with a center AF button is just below the indented thumb rest. With it, you pull up flash options (including a no-brainer wireless on/off), ISO sensitivity settings, display choices, and drive mode options. The latter includes an interesting 3- or 5-shots-in-10-seconds self-timer mode and rather limited bracketing: just exposure, for 3 shots in 1/3 or 2/3 stop increments. Above the navigation switch is the Fn button, with which you access all your frequently needed shooting settings plus some others: autofocus mode, AF area, metering mode, D-Range Optimizer, white balance, and Creative Style. There are no novel options here, but in a nice interface touch, some text pops up to clarify the purpose of a setting if you pause for too long without making a selection. You have to go into the menu system to set image quality, flash compensation, and toggle the image stabilization, but there's nothing truly buried or misplaced in the user interface. Of course, with the relatively basic feature set, there's not a lot to hide. (For a complete list of features and guide to the camera's parts, you can download the PDF manual.)
