Conclusion: That said, when weighing these up against a superb level of image quality when shooting in most conditions, great handling, good build quality, industry-leading EVF, quick full-time phase detection AF system and a comprehensive set of exposure modes, we have little trouble with recommending this excellent camera.
Summary: The A77 is a well-designed camera which spans the mid-range and semi-professional categories. Its headline features - high pixel count and blazingly fast continuous shooting - will attract a lot of interest, but of greater utility in day to day use are its effective ergonomics, reliable systems and excellent full-time live view system and full-time AF.
Pros: Excellent 2.4 million-dot OLED EVF, Versatile full-time live view system, Very high-resolution 24MP CMOS sensor (but see caveats in 'cons', below), Exceptionally 'deep' feature set including Auto HDR and Sweep Panorama, Class-leading video resolution, Solid, well thought-out ergonomics, Fast and responsive operation, Very good continuous shooting performance (particularly with UHS-I memory card), Efficient SteadyShot INSIDE image stabilization system, In-camera GPS, G...
Cons: In-camera JPEGs don't show off the 24MP sensor to its best extent, Comparatively strong noise reduction at medium and high ISO settings, Very noisy raw files at high ISO settings, Little control over high ISO noise reduction in JPEG mode ('auto' or 'weak'), Limited control in 12 fps continuous shooting and movie modes, No live view in 8 or 12 fps continuous shooting modes makes accurate panning very difficult, Menu system a little confusing (hard to orientate yourself...
Summary: So the Alpha A77 may not be a DSLR, but that fact shouldn't deter anyone seeking a versatile interchangeable-lens camera from checking it out. The sum of its parts is a "not a DSLR" to get very excited about, as it seems to cover more ground than any similarly priced DSLR in terms of high-speed capture, video capabilities, autofocus skills, creative in-camera filters, and fun-to-use modes.
Summary: While other manufacturers incrementally improve on the traditional SLR format Sony has shown it's not afraid to innovate by introducing radical new designs into its line-up. The SLT-A77 takes the fixed mirror concept several steps towards becoming a compelling alternative to cameras with reflex mirrors.
But it's not all about the SLT technology. The A77's 24.3 Megapixel sensor is the highest resolution APS-C sensor available to date.
Pros: Big, bright ultra high resolution EVF., 12fps burst mode with AF., 1080p60/50 movie mode., Continuous AF in movie modes ., High quality bright 16-50mm kit lens., 24 Megapixel sensor.
Cons: Limited exposure control at 12fps., Limited movie AF with Manual exposure., Poor menu layout and organisation., Poor battery life compared to a DSLR.
Summary: An impressive specification has certainly grabbed the attention here, and the Alpha 77 has been given more than a few tweaks over its predecessor. Sony has set the bar in several areas, not least of which is the inclusion of a high-resolution imaging sensor and superb LCD screen. Furthermore, it is not implausible that Sony has paved the way for electronic viewfinders to one day replace the optical type.
Summary: With its 12fps burst speed and 24.3MP sensor the Sony A77 packs quite a punch.
Pros: Fastest continuous shooting speed in its class, Excellent image quality, Generous range of HD movie recording options, Lots of useful features and customisation options, EVF is the best we've yet seen
Cons: EVF still not as good as a traditional viewfinder
Summary: The Sony SLT-A77 is the long-awaited replacement for the DSLR-A700, Sony’s previous ‘semi-pro’ DSLR. The A77, of course, isn’t actually a DSLR (Sony doesn’t make them any more), despite looking and handling very much like one. Instead it’s an SLT camera with no pentaprism and no moving mirror, these bits being replaced by a translucent mirror and electronic viewfinder.
Excerpt: A little over five years after the system-launching A100 first saw the light of day comes the Sony D-SLR that should genuinely strike fear into the hearts and minds of its rivals. To date, Sony’s progress through the D-SLR world has been steady, but largely unremarkable. This isn’t to detract from its rapid rise to the number three spot in most major markets and the general acceptance of the brand as a key player in the sector, but it hasn’t really done anything that...
