Sony A7: Features
One of the by-products of a full-frame sensor is that it produces a large amount of data, and as a result it can present some issues when it comes to processing speeds. Sony has looked to address this issue with the Sony Alpha 7 through the inclusion of the BIONZ X processor. The processor is new to the Alpha 7 and includes a range of cleaver features, including diffraction reducing technology and area-specific noise reduction. It allows for a burst mode of 5fps – dropping to 2.5fps with exposure and AF active between shots – while the Alpha 7 also offers an ISO range of 100-25600.
The full-frame sensor itself takes shots at 24.2MP and, unlike its sister camera the Alpha 7R and a host of other recent compacts and DSLRs, retains the optical low pass / anti-alias filter. Another welcome feature of the A7’s sensor is the presence of on-chip phase-detection AF technology complete with 117 phase-detection points. These phase detection points combine with a 25-point contrast-detect system in what Sony is labelling its hybrid Fast Intelligent AF system.
The combination of the Fast Intelligent AF system along with the BIONZ X processor will, Sony claims, result in a 3x faster AF performance than found on systems utilising the previous processor.
As you’d expect for a high-end Sony camera, the A7 has full support for both NFC and Wi-Fi functionality. Unlike some other manufacturers, Sony’s Wi-Fi and NFC functionality is certainly complete, allowing for the wireless transfer of images to either smartphone or tablet, as well as remote control of the camera through the dedicated app.
One feature missing from the Sony Alpha 7 is any sort of built-in flash, and it's also lacking in a bundled in flashgun. Instead, if you’re after a flashgun you’ll have to purchase one of the Sony units compatible with the camera’s Multi Interface Shoe.
Thanks for review, it was excellent and very informative.
