Sony’s A77 and A65 Alpha DSLRs with Translucent Mirrors Deliver 24.3 Megapixels


San Diego, CA—Sony says its latest Alpha DSLRs for advanced amateurs and photo enthusiasts, the SLT-A77 and SLT-A65, are engineered for “blazing speed, enhanced image quality, high resolution and incredible performance.”

The latest refinements to Sony’s Translucent Mirror technology help make these cameras the fastest interchangeable-lens cameras in their class. The α77 and α65 employ a newly developed Exmor APS HD CMOS sensor with 24.3-megapixel resolution and XGA OLED Tru-Finder viewfinders with 100% frame coverage and a wide field of view. The sensor teams with the next generation of Sony’s Bionz image-processing engine to handle huge amounts of high-speed data for fast response times and low-noise quality whether shooting photos or Full HD video.

The α77 boasts fast continuous autofocus shooting performance, with specs stating it captures a burst of full-res 24MP images at 12 frames per second with full-time phase-detection AF. The α65 achieves a 10-fps shooting speed. AF tracking of moving subjects is more precise with the α77 due to a new 19-point autofocus system with 11 cross sensors. The α65 has 15-point AF with three cross sensors. Tracking Focus maintains focus lock on a moving subject even if the target is momentarily obscured. Additionally, a new electronic front shutter curtain is engineered to achieve a minimum release time lag of 50 milliseconds.

A sensitivity range of ISO 100-16,000 expands (α77 only) down to ISO 50. And at the highest sensitivities, both cameras can freeze fast action or capture atmospheric low-noise shots without flash.

Users are given customization capabilities through the XGA OLED Tru-Finder viewfinder and can preview the effects of adjusting exposure, white balance and other settings in real time. They can also make fine focus adjustments via a zoomed-in portion of the image. Additionally, the “smart teleconverter” displays an enlarged central portion of the image sensor, allowing compositions to be displayed on the viewfinder and captured as 12MP images with a digital zoom factor of 1.4x or 2x.

Other features include: Full HD video capture at 60p (progressive) frame rates, incorporating the recently introduced AVCHD Progressive (v2.0) format, with 24p shooting available; manual focusing and P/A/S/M exposure modes during video capture; an adjustable-angle 3.0-inch LCD display; and revised ergonomics, such as a contoured grip design and tactile new button layout for “eyes off” operation while viewing via the viewfinder.
The α77 adds front and rear control dials for fingertip operation and a separate top-mounted LCD data display. Its body has magnesium alloy panels, and key controls are sealed against dust and moisture, complementing similar levels of protection offered by the new SAL1650 lens, VG-C77AM vertical grip and HVL-F43AM flash unit. And, the new shutter unit on the α77 is tested up to 150,000 cycles and supports 1/8000-sec shutter speed (1/250 sec flash sync). Onboard GPS allows automatic geotagging of photos and video clips with location data.

The α77 is compatible with Sony’s Memory Stick Pro-HG Duo HX series as well as SD memory cards.

                             New DT 16-50mm f/2.8 SSM Zoom Lens
The growing range of compatible A-mount lenses for both cameras now includes the DT 16-50mm f/2.8 SSM standard zoom with 16mm wide-angle coverage for both portrait and everyday shooting. The lens features a dust- and moisture-resistant design and a zoom range of 3x at its constant wide f/2.8 aperture. Aspherical glass and three ED (Extra Low Dispersion) lens elements help minimize aberration at all focal lengths, while a super-sonic wave motor (SSM) drive enables fast, quiet autofocus.

The new α77 Translucent Mirror interchangeable-lens camera is available in a kit with the SAL1650 f/2.8 lens for $2,000 and is offered body-only for $,1400.
The SAL1650 lens is also sold separately for $700. The VG-C77AM vertical grip for the α77 is available for $300.

Sony’ s α65 Translucent Mirror interchangeable-lens camera is available in a kit with a standard 18-55mm lens (SAL1855) for $1,000 and is offered body-only for $900.
