Sony Alpha SLT-A55 assessment by Chris Please
Sony Alpha SLT-A55 review articleThe initial step in taking a photo is to point the camera within the correct direction. But to know what that right direction is, you’ll need a viewfinder. The issue with designing a viewfinder is the fact that the lens on the camera is located in front with the image sensor, so it’s tough to obtain your eye straight behind the lens.
SLRs get about this issue by utilizing a flip-up mirror to bounce light into the optical viewfinder. Most digital cameras, though, merely use the Lcd Screen on the back with the camera to show the present framing.
The difference between the Sony Alpha SLT-A55 and any camera that’s come prior to, is that Sony has placed a translucent mirror in front with the image sensor. It doesn’t move, such as the mirror in an SLR, and simply because it’s mostly transparent, the bulk of the light coming via the lens passes on towards the sensor. A tiny bit, although, gets bounced upward to the camera’s autofocus sensors. The practical upshot of this really is that the camera can do what couple of SLRs can: continuously autofocus in Live View mode. When shooting video, this makes for a camera that handles like a point-and-shoot, but that provides the flexibility and superior image high quality of an SLR.
Camera design
The Sony Alpha SLT-A55 is really an about the same size as competing mid-range digital SLRs. Small and lightweight, the camera is sturdily constructed, and offers a secure grip and well-designed interface. A large rear-mounted LCD screen flips out from the back with the camera. You are able to spin it about to match it flush using the camera’s back, or tilt it up or down. It’s hinged at the bottom, rather than the side, but it nonetheless offers all of the range of motion you need for above-the-head or waist-level shooting.

For self-portraits, the only way to face the screen forward is to tilt it so that it sticks straight down, below the camera. If you mount the Sony Alpha SLT-A55 camera on a tripod, you may not have the ability to see the screen when it is sticking straight down. A proximity detector automatically switches from the rear LCD to the eye-level electronic viewfinder whenever you raise the camera for your eye, and the A55’s electronic viewfinder is extremely great, offering a large, bright, clear view of one’s scene.
Sony has added a truly cool real-time level inside the Sony Alpha SLT-A55’s viewfinder. Because the camera tilts, a virtual horizon line shows you whether you’re level or not. Handy and non-obtrusive, the level doesn’t get within the way of the rest with the status info. All that said, I’m not a fan of electronic viewfinders, merely because their dynamic range is limited by the camera’s sensor. So, in the event you want to have the ability to see details in both vibrant highlights and deep shadows when you are composing, you’ll be out of luck. This really is an essential consideration when weighing this camera against a conventional SLR.
As with other Sony cameras, the Sony Alpha SLT-A55 consists of a stabilized sensor, which means that any of Sony’s excellent lenses will deliver stabilized imagery. The A55 is compatiable with Sony’s ? lenses, Minolta lenses, and Konica Minolta AF lenses. There’s an in-camera pop-up flash, as well as an iISO hot shoe mount if you’d like to make use of an external flash. As with other Sony DSLRs, the proprietary hot shoe mount works with Sony and Minolta products, but an adapter can be bought separately if you’d like to turn it into a standard mount to use it with Nikon, Canon, Pentax, or Olympus accessories.
Special functions
Because the Sony Alpha SLT-A55 does not have to move a mirror about, Sony has been in a position to get a remarkable ten frame-per-second burst rate out of the camera. It is continuously autofocusing in this mode, so quick moving subjects remain sharp. In addition to giving you a great advantage when shooting sports, animals, and other fast-moving subjects, the A55’s burst speed permits some other handy functions. The camera’s Sweep Panorama function permits you to shoot stitched panoramic pictures by simply holding down the shutter button whilst panning across a scene. The camera automatically captures overlapping images and stitches them with each other, and the outcomes are very great. No trip to Photoshop or other image editor is needed.
The Sony Alpha SLT-A55 also provides a multi-frame noise reduction function. If you are in low light, and are worried about your pictures becoming too noisy, this feature permits you to shoot a burst of pictures. The camera then combines them to produce a low-noise outcome. Because of the camera’s high burst rate, you can rattle off a couple of shots very quickly, giving you a better opportunity of shooting pictures in close registration.
Whilst ten frames per second may not be that big a deal to photographers used to high-end, pro-level cameras, to get such speed at this price point is a real breakthrough for those that want speedy shooting.
Settings and controls
The Sony Alpha SLT-A55 offers a full complement of auto and manual modes. Full auto, program, priority and manual modes are all accessible from the top-mounted mode dial, and controlling exposure parameters is simple and intuitive. The A55 does very nicely in low light, as much as around ISO 6400. After that, issues get pretty noisy, but Sony has included their unique multi-shot noise reduction feature, which shoots numerous images, and then combines them to reduce noise.
Surprisingly, the Sony Alpha SLT-A55 lacks any type of System Shift function, for cycling through reciprocal exposures in System mode. This is a superb method to maintain some manual control whilst shooting in Program, and is sorely missed on the A55.
Video
The Sony Alpha SLT-A55 shoots full 1080p AVCHD video, and shooting video with this camera is much simpler than with any digital SLR. Because the camera can continuously autofocus whilst shooting video, you do not have to be concerned about how you or your topic moves while rolling video. The camera’s quick autofocus mechanism will keep your scene in concentrate, even throughout difficult camera movements. Sony has wisely included an external mic jack, since handling the camera while shooting video generates plenty of hand-holding noise.
Image and video tests
The Sony Alpha SLT-A55 received impressively high ratings in our lab’s subjective image and video tests. We tested it alongside the Sony A580 and Nikon D3100 DSLRs. The A55’s scores had been very close towards the A580, and it did slightly better than the D3100. It received word scores of Very Good for exposure, colour, and sharpness, but only a great for distortion (the 1 category exactly where the A580 did noticeably much better).
The video high quality on the Sony Alpha SLT-A55 was one of the best we’ve seen on an interchangable lens camera within the past year, especially in bright light, earning a word score of Superior. Watch the sample clips from our subjective video tests (for each vibrant light and low light) beneath. Select 1080p within the drop-down menu within the lower-right corner of each player to determine every clip at maximum resolution.
