Sony Alpha 77 review


Price as reviewed:


The Competition

With its unique technology in today’s market, in many respects the Alpha 77 stands alone. Given its price and position as Sony’s flagship APS-C-format camera, though, its direct competition would include the Pentax K-5, Canon EOS 7D and Nikon D300S. Like each of these cameras, the Alpha 77 has a magnesium-alloy build and, like the K-5, it is weather-sealed.





However, the fact the Alpha 77 has the highest pixel count of any APS-C-format model, a fixed translucent mirror, can shoot at 12fps, plus a tiltable, articulated screen and EVF means the Sony camera certainly stands out from the crowd.

That said, the fixed mirror and more crowded sensor result in a less impressive performance in low light, but in all other areas of image quality the Alpha 77 matches its competition. This is impressive given that the high-resolution files can be reproduced to a much larger scale.
