The new Sony Alpha A58 is Sony's latest mid-entry level Digital SLR offering with Sony's Translucent Mirror Technology, and a new 20.1 megapixel APS-C sensor, it is designed to replace the Sony Alpha A57, as well as the Sony Alpha A37 which will be discontinued in April. It features a new OLED TruFinder electronic viewfinder, lock on AF tracking, and auto-object framing. It will be available for £450 with the new 18-55mm SAM II kit lens from April.
The camera features a new OLED TruFinder electronic viewfinder, an improvement over the LCD viewfinder in the A57, although the resolution is the same with both cameras featuring the same 1.44 million dot resolution.
Auto object framing, will automatically frame portraits, macros or AF Tracking subjects, and crop accordingly while also retaining the original image. This feature is an update to auto-portrait framing on previous models, and can be switched off if unneeded.
Lock on AF is another new feature that will automatically detect the subject size and track the movement accordingly. The new 20.1 megapixel sensor offers ISO100 to ISO16000, with area based noise reduction for improved low light performance.

The Sony Alpha A58 has a plastic front lens mount, however, on closer inspection of this camera and the A57, the next ring in is also plastic, followed by a silver metal ring on both. Sony assured us that this shouldn't cause any issues in use.
The rear has a 460k dot screen, and an OLED Trufinder electronic viewfinder with 1.44million dots - and it appeared to look better than the A57 in comparison with a more life-like view. The remote socket has gone from the A57, and instead a new RM-VPR1 wired remote commander accessory is offered.
On top you'll notice that the A58 has followed other recent Sony Alpha and NEX cameras and features a more ISO standard flash hot-shoe, with the Multi Terminal Ni accessory port. The camera offers a battery life rating of 690 to 700 shots depending on where you use the EVF or LCD display, with the LCD offering slightly better battery life.
The OLED TruFinder has eye-detection and will automatically switch to the electronic viewfinder when you hold the camera up to your eye, or alternatively you can use the button on the top to manually choose. We will be putting the Sony Alpha A58 through our full review when available.
