Overview — Sony a77

The Sony Alpha 77 is a feature-rich DSLR built around a 24.3MP APS-C sensor paired with Sony's BIONZ image processor. It offers a native ISO range of 100 to 16000, giving photographers solid flexibility across a range of lighting conditions. The camera's phase-detection autofocus system delivers 19 focus points along with subject tracking, keeping moving subjects sharp during continuous shooting.

Speaking of which, the Alpha 77 supports a burst rate of up to 12 frames per second at full 6000x4000 resolution — a genuinely impressive specification for still photography work. On the video side, the camera captures up to 1080p footage at frame rates of 24fps, 30fps, and 60fps, with color profile options including Standard, Vivid, and Neutral. The Alpha 77 features in-body sensor-shift image stabilization, helping to reduce camera shake without relying on the lens.

The electronic viewfinder resolves at 2,359,296 dots with a 60Hz refresh rate, providing a detailed, fluid shooting experience. A tilting 3-inch LCD with 921,600 dots aids in flexible framing. The magnesium alloy body is weather sealed, measures 142.6 x 104.0 x 80.9 mm, and weighs 732g.

It includes a 3.5mm microphone jack and Mini HDMI output, and accepts SD, SDHC, SDXC, and Memory Stick PRO Duo cards. The battery is rated for 470 shots per charge.
