Sony Alpha SLT-A35 review: Sony Alpha SLT-A35

Its burst shooting clocked in at 5.0fps, which is excellent for its price class. The viewfinder actually updates quickly enough that I could pan comfortably while shooting, at least on only moderately fast subjects (like a bicyclist in NYC traffic) which is unusual in ILCs. And the continuous autofocus seemed to keep up pretty well.

The LCD is serviceable--there's nothing particularly notable about it--and the contrast is different between the viewfinder and the LCD which can make fine exposure determinations difficult. Nonetheless, the viewfinder is relatively large and magnified compared to competitive dSLRs, and I like the stabilizer indicator in it which helps you pick the best moment to shoot.

Its design remains pretty similar to the other SLT models: SLR-like but with an electronic viewfinder. It's relatively lightweight for its size, with the same functional--if somewhat uninspiring--design as the rest of Sony's SLRs. I was disappointed that the A35 doesn't pick up the interface convention of the new C3, wherein it will tell you why a particular option is grayed out.

It's got a typical layout, with direct-access buttons for drive mode, ISO sensitivity, white balance and display options, plus a function button to pull up access to frequently used settings like drive mode, flash, focus area and mode, metering and ISO sensitivity. My biggest problem here is that there's no way to quickly change image quality; if you switch between burst JPEG shooting and single shot raw+JPEG that's essential. An even bigger problem is the placement of the movie record button, which is on the right shoulder of the camera next to the exposure compensation button (and further left, the exposure lock button). I consistently hit the exposure compensation button and couldn't figure out why recording hadn't started.

Sony puts the mode dial on the left shoulder of the camera. It's a good location, since it frees up the right side for controls better operated by that hand. That said, I'm not sure the D-Range Optimizer button is the best choice for that spot, though you really couldn't put any button/dial combo button there as long as the dial needs to be operated by your forefinger.

In addition to the typical PASM modes and a couple of auto modes, the mode dial has a new Tele-Zoom high-speed shooting mode is just a digitally zoomed 8-megapixel 7fps burst mode, 3D and Sweep panoramas, and a handful of scene and special effects modes. Unlike some competitors, Sony's Auto Plus just adds on some more automation like Auto HDR rather than making it auto plus some exposure controls.

Conclusion
With excellent photo quality, better continuous-shooting performance than a lot of the dSLRs in its price range and solid autofocus behavior during video capture, the Sony Alpha SLT-A35 has a lot to recommend it as a step up from a point-and-shoot. But it also lacks some of the design pizzazz--or simply basic attractiveness--of some competitors, and can be a little annoying to shoot.
