Sony Alpha a99 SLT-A99V review: This camera is a jack-of-all-trades

Both the viewfinder and back display work very well, with no visibility issues in direct sunlight or refresh issues while shooting action, and though I still think that OLED displays are a little too cool and contrasty for cameras -- photos never look better than on those displays, and that's not necessarily a good thing -- Sony lets you adjust the color temperature of the viewfinder.

Design and features
For the most part, the camera body is very well designed and built, with a great grip -- one of the most comfortable I've used -- and an intelligent control layout. It's weather-sealed, though keep in mind that as far as I know Sony only offers two full-frame weather-sealed lenses to match. Yes, the body is also lighter than the competition, but I find once you stick a good lens on it that roughly 6-ounce advantage becomes moot.

All the controls are easily accessible and distinguishable by feel, the mode dial has a central lock button (not my favorite place for it), and everything is as configurable as you'd expect from a camera in its class. I don't think it's the snazziest design -- I'm not crazy about the bulbous look of the buttons boiling up from the surface on the back -- but it's effective and that's more important.

There's only one control I really dislike, and that's the navigation joystick. It simply feels mushy and imprecise.

While I think competitors produce better video quality than the A99V, this is my favorite camera for shooting video. It's one respect in which the fixed-mirror SLT technology gains a huge advantage over SLR. The articulated OLED display, great EVF, and manual-focus peaking make it extremely easy and comfortable to shoot without having to Frankenstein the camera out with a rig, loupe, and other accoutrements. The one, somewhat huge, exception to the love: you can't adjust shutter speed or aperture for video while autofocus is enabled. A lot of videographers use manual focus exclusively, so it won't faze them, but it irks me to no end. And if you don't know this up front, you can spend hours trying to figure out why the camera won't let you adjust those settings.

Sony brings its Silent Controller from its prosumer camcorders for better video control.

While the Silent Controller is intended to allow you to avoid introducing noise while changing settings during video shooting, it's also really nice for simply changing settings without having to drop the camera from your eye. It offers a lot of the same settings as the function menu, but it has a different interface that takes up far less space in the viewfinder.

In addition to the complete set of essential features for a pro camera, the A99V has a couple of unique features for this class, including built-in GPS (which strains the already lackluster battery life a bit), in-camera image stabilization (both Canon and Nikon use lens-based IS), and a built-in stereo microphone (which is nice to have in a pinch). On the downside, some folks may quibble with the decision to incorporate two SD card slots instead of an SD and a CompactFlash; while it would likely make little difference during shooting, CF is still the faster technology for moving files to your computer in a time-sensitive workflow.

If you're a Sony A series shooter disgruntled by the company's lack of tethering support for most of its modern models, the company has updated its Remote Camera Control software to support the A99V. And one note about accessories: the A99V uses the new Multi Interface Shoe, but ships with an adapter if you want to use your old accessories.

For a complete account of the A99V's features and operation, download the PDF manual.

The A99V is a powerful, complicated camera that may simply exceed the needs (or budget) of most photographers, and since Sony doesn't offer a cheaper full-frame model a la the Nikon D600 or Canon EOS 6D, the company's missing out on an opportunity. If you need a single model that can handle both stills and video with equal aplomb, and are willing to make some trade-offs -- sacrificing a little on the video and high-ISO quality as well as video AF -- it's a great choice.
