The Sony Alpha SLT-A55 pairs a 16.2 MP APS-C sensor with Sony's BIONZ image processor and an impressive 10 fps burst rate, making it a capable choice for photographers who need speed. The ISO range of 100 to 25600 covers a wide variety of lighting conditions, while in-body sensor-shift image stabilization helps reduce camera shake when shooting handheld. The OLED EVF delivers a sharp 1,152,000-dot image at a smooth 60Hz refresh rate, complemented by a 3.0-inch Vari-Angle LCD with 921,000 dots for flexible off-axis shooting.
A 15-point phase detection autofocus system handles focus acquisition, and the built-in pop-up flash with ADI/Pre-flash TTL adds a convenient on-camera lighting option. Video capture reaches 1080p at 60fps in 8-bit color, with a 3.5mm microphone jack for external audio. The body is built from polycarbonate with a metal chassis, measures 124 x 92 x 85 mm, and weighs 500g.
Storage is handled via SD, SDHC, SDXC, or Memory Stick media, and the camera connects externally via Mini HDMI and USB. Note that weather sealing is not included.
