Sony SLT-A58

Дата публикации: 01.04.2013

Первые слухи о появлении этой камеры просочились в сеть еще в январе текущего года. Спустя месяц Sony SLT-A58 была официально представлена, а еще через месяц камера попала к нам на тестирование.

Sony SLT-A58 - камера с полупрозрачным заркалом, которая пришла на смену модели SLT-A37. Таким образом производитель оставил в сегменте начального уровня только одну модель вместо двух: SLT-A37 и SLT-A57. Теперь в линейке зеркальных камер полный порядок, и выбор для новичка стал менее трудоемким.

Главным новшеством модели SLT-A58 является матрица Exmor APS HD CMOS с высоким разрешением 20 Мп. Новый процессор обработки изображения BIONZ позволяет снимать фото с высоким уровнем детализации и низким уровнем шумов, обеспечивая широкий диапазон чувствительности ISO от 100 до 16000. Предыдущая 16-мегапиксельная матрица Sony неплохо себя зарекомендовала в целом ряде камер. В ходе нашего теста постараемся выяснить, действительно ли с новой 20-мегапиксельной матрице снимки стали лучше?

Основные особенности модели:

  • новая 20-мегапиксельная КМОП-матрица формата APS-C;
  • конструкция с полупрозрачным зеркалом;
  • скорость серийной съемки до 8 кадров/с;
  • 2,7-дюймовый откидной дисплей с разрешением 460800 точек;
  • электронный видоискатель OLED Tru-Finder с разрешением 1440000 точек;
  • автофокус с 15 датчиками, 3 из которых — крестовые;
  • видеосъемка Full HD;
  • новый для Sony горячий башмак ISO 518;
  • обновленный китовый объектив.

Sony SLT-A58: Digital Photography Review

Discuss in the Sony Alpha SLR/SLT A-mount Talk forum

The Sony Alpha SLT-A58 is a mid-range SLT camera with a newly-developed 20MP sensor. The A58 will replace both the A37 and A57 models, helping to simplify the company's lineup. The A58 builds on the A57's feature set and gains an SVGA (800x600 pixel) OLED viewfinder, rather than its predecessors' LCDs. It also boasts a new lock-on focus mode and Auto Object Framing mode - an extension of the auto portrait mode in the A57.

Sony Alpha 58 (SLT-A58K)

The Sony Alpha 58 ($599.99 direct with 18-55mm lens) is the current entry-level D-SLR in the company's catalog. The 20-megapixel camera offers a few modest upgrades over the previous-generation Alpha 57, including an OLED viewfinder, but takes a step backwards in terms of burst shooting speed. If you're in the market for a D-SLR with an EVF, we think the Alpha 65 is a better buy, though it is a bit more money. Traditionalists who prefer an optical finder are better off with our Editors' Choice, the Nikon D5200.

Design and Features The Alpha 58 is pretty typical in size for an entry-level D-SLR. It measures just 3.9 by 5.1 by 3.1 inches (HWD) and weighs 1.3 pounds without a lens. The Canon EOS Rebel T5i is about the same size (3.9 by 5.2 by 3.1 inches), but a bit lighter at 1.1 pounds. Like other Sony D-SLRs, the viewfinder is an EVF rather than an optical design. The camera still has a mirror, but it's semi-transparent and doesn't move. Most of the light hits the image sensor, but some is directed down to a dedicated phase detect autofocus sensor. This provides a seamless transition between the EVF and the rear LCD, and fast, accurate focus for both stills and video.

The EVF is an OLED design with a 1,440k-dot resolution. It's a step up in quality from the LCD found in the Alpha 57, but it's not the equal of the 2,336k-dot OLED viewfinder that Sony packs into its Alpha 65 and Alpha 77 cameras. That EVF is noticeably sharper, giving you a better idea of what you're shooting. The rear LCD on the Alpha 58 is a little lacking as well; it's a 2.7-inch panel with a hinged design so that it can tilt up or down. The resolution is 460k-dots, which is only half that of others in this class like the Pentax K-50.

The small LCD does leave a bit of extra room on the body for controls. On the rear you'll find buttons to record movies, activate exposure lock, and adjust exposure compensation. Below those, directly to the right of the LCD, you'll find the Fn button, which lets you control shooting settings via an on-screen menu, and a four-way control pad with directional buttons to adjust the information displayed over the live view feed, change the drive mode and activate the self-timer, adjust white balance, and control color output. The center AF button enables tracking focus, and there are also the standard image playback and delete buttons. The latter doubles as an on-screen guide that contains tips for the best settings for different types of photos. The menu button is located above the LCD, to the left of the EVF's eyecup.

Up top there's a mode dial, which has a few additional options beyond the standard settings. There's one for scene modes, which set the camera to correct settings to capture different types of photos, as well as a special telephoto crop extends the reach of your lens and increases the maximum burst shooting speed, but reduces photo resolution to 5 megapixels. To the right of the EVF are the power switch, shutter release, ISO control, a toggle to change between the rear LCD and EVF (there is an eye-sensor if you'd like that to be automatic), and a button marked Zoom. This enables Sony's Clear Image Zoom (for JPG shots only), which lets you enable as much as 2x digital zoom to extend the reach of your lens; images are saved at the full 20-megapixel resolution when using this function.

There's a single control dial on the front of the handgrip. Most cameras in this class only offer a single control dial (which changes function based on the mode you're in). Of the sub-$1,000 D-SLRs, only the Pentax K-50 (and it's non-weather-sealed sibling, the K-500) offer front and rear control dials. That's a feature that comes in handy when shooting in manual mode, but is also useful in other situations, including shooting manual with automatic ISO so that you can control shutter speed and depth of field without having to worry about calculating exposure. The Alpha 58 does support that function; to adjust the shutter speed in manual mode you simply use the front dial, and if you hold down the exposure compensation button the front dial function changes to control aperture.

Sony announces SLT-A58 20MP mid-level DSLR-style camera

Sony has announced the Alpha SLT-A58, a mid-range SLT camera with a newly-developed 20MP sensor. The A58 will replace both the A37 and A57 models, helping to simplify the company's lineup. The A58 builds on the A57's feature set and gains an SVGA (800x600 pixel) OLED viewfinder, rather than its predecessors' LCDs. It gains a new lock-on focus mode and Auto Object Framing mode - an extension of the auto portrait mode in the A57. It will be sold with a redesigned DT 18-55mm F3.5-5.6 SAM II kit lens that offers quieter autofocus. The camera is not being launched in the USA at this point.

Press Release

At the heart of the α58 is a brand new Exmor APS HD CMOS sensor with an extremely high resolution of (approx.) 20.1 effective megapixels. It’s teamed with an improved BIONZ image processing engine for exceptionally detailed, low-noise stills and Full HD video, plus an extra-wide sensitivity range of ISO 100 to 16000.

Pick from the choice of 35 interchangeable A-mount lenses (including two tele-converters) and experience flawless images in virtually any lighting conditions, from dimly-lit interiors to atmospheric twilight scenes. Even if you’re shooting handheld, SteadyShot INSIDE keeps pictures crisp and stable, letting you shoot with confidence at slower shutter speeds or higher zoom settings where wobbles are often a worry.

Unlike ordinary DSLR cameras, SLT cameras by Sony use Translucent Mirror technology that directs light onto the main image sensor as well as a separate autofocus sensor. This means that subjects stay sharply focused at all times as you compose scenes with the tilt-angle LCD or through the high-resolution, high-contrast OLED Tru-Finder. And with no moving mirror to slow you down, you’ll enjoy non-stop live image preview during speedy burst shooting or while you’re recording Full HD video.

The α58 is your ideal partner for grabbing the action as it happens – like sports, wildlife or spur-of-the-moment fun with friends and family. Tele-zoom Continuous Advance Priority AE mode brings that decisive moment closer with a high-speed burst of sharp images at 8 frames per second. The high-performance 15-point AF system now features Lock-on Autofocus with speedier, more accurate subject tracking. So now you can capture the athletic grace of a gymnast or animals in the wild with a burst of crisply-focused images, even if your subject’s moving.

Featured on previous models, Auto Portrait Framing has now evolved into even more versatile Auto Object Framing – helping you get better-looking, more professional results without effort. The α58 judges what’s in the scene – one person, two people, even moving objects or macro subjects – tracking, framing and cropping the shot to create powerful, professionally-framed compositions. Thanks to Pixel Super Resolution Technology by Sony, cropped images preserve the same resolution as the original exposure.

Instantly selectable from the mode dial, Picture Effect lets you pick from a palette of 15 artistic ‘in-camera’ treatments, like Toy Camera, Mono and Partial Colour.

Framing, focusing and viewing your shots is a pleasure through the new OLED Tru-Finder. This bright, high resolution electronic viewfinder accurately shows the results of adjusting camera settings in real time. Instantly see the result of adjusting exposure compensation, aperture, ISO, white balance, Picture Effect and other parameters before you shoot… not after. It’s a great way to compose the perfect shot with confidence.

The α58 is the first-ever A-mount interchangeable lens camera from Sony that offers support for new ‘TRILUMINOS Colour’. You’ll experience a dramatically expanded palette of vivid, ultra-realistic colours when videos and still images are played back on any BRAVIA TV with support for ‘TRILUMINOS Display’.

The new α58 interchangeable lens camera from Sony with Translucent Mirror technology is available from April 2013.
