Announced by Sony on August 24, 2011 and launched alongside its brother the Sony Alpha 77, the Sony Alpha 65 is the top-tier for Sony's midrange Alpha SLT camera line.

The Sony Alpha 65 doesn't have a direct predecessor like the Sony Alpha 77 however is still considered a replacement for the Sony Alpha 700 with less high-end specifications than its brother. The A65 lacks the A77's magnesium alloy construction in favor of a polycarbonate resin (plastic) resulting in a lighter frame and slightly smaller dimensions and lacking weather-proofing capability. The A65 uses the USB 2.0 transfer interface of 480 Mbit/s, has HDMI type C for connectivity and remote capabilities using the RM-S1 accessory.

The camera enters the market with its own tier entry into the range, boasting features such as a 24.3Mpx APS-C HD CMOS sensor using a single-lens translucent mirror and features full HD 1080p recording capabilities using H.264 compression. It hosts a variable burst-shooting mode up to 10fps, stereo audio recording capabilities and like others in the Sony Alpha range it has high sensitivity with ISO 100 to 16000, several noise reduction features, 8 white balance presets including custom balance and exposure control systems. The battery capacity is rated for 510 shots using the electronic viewfinder or 560 shots using the LCD. The capture format for images in RAW format uses the .ARW extension, Sonys extension for RAWs.

The rear panel has the same layout as the Sony Alpha 55 and whilst the LCD hosts a 4:3 aspect ratio compared to the A55's 16:9 it has the same resolution and adjustability. With a few minor layout changes one easily noted oddity is the reversal direction of the power switch compared with the A55 believed to result in an easier operation.
