Users can select the variable zoom on both models to scan a wide area at low magnification before zooming in seamlessly to pinpoint a subject, such as birds in a field. Turning on the digital zoom at magnification settings over 10x boosts the DEV-5 model’s total magnification range from 0.9x up to 20x digital (image quality is reduced when digital zoom is on and recording 2D video at magnifications higher than 10x), rivalling many high-powered conventional binoculars. The DEV-3 model pulls wildlife, sporting subjects and architectural details closer with a maximum magnification of 10x optical. In 3D mode, the binoculars’ maximum magnification is 5.4x optical.
Unlike traditional binoculars, electronic autofocus keeps moving subjects sharply in focus at all times. A comfortably positioned dial allows fingertip adjustment of manual focus – ideal for focusing selectively on a subject, rather than overhanging branches or other obstructions in the field of view.
Electronic autofocus allows both binoculars to focus cleanly on subjects less than half an inch away when recording in 2D (minimum of 32 inches when recording in 3D).
Separate images for left and right eyes are captured by a matched pair of precision G Lens optics by Sony with “Exmor R” CMOS sensors and powerful Bionz processors. Independent electronic viewfinders provide clear, detailed images for left and right eyes, offering a stereoscopic viewing experience that’s comfortable, natural and highly immersive.
The DEV-3 and DEV-5 digital binoculars feature Optical SteadyShot image stabilization (Active mode), the optical stabilization system that’s found on Sony Handycam camcorders and Cyber-shot cameras. Optical SteadyShot image stabilization helps keep images clear and stable, even when viewing at high magnifications. The binoculars can be connected via HDMI to a Sony Bravia HDTV or any HD television with HDMI input for viewing images (cable sold separately). 3D videos can be enjoyed on virtually any 3D-compatible TV, including Sony Bravia models. There’s also a USB connection for transferring video clips to a PC for storing, editing and sharing.
The DEV-5 model includes an on-board GPS receiver that automatically geo-tags video clips and photos. Tagged images can be viewed after shooting in online maps (requires compatible software).
Both binocular models come with a high-capacity rechargeable battery pack (NP-FV70) that allows up to approximately three hours of 2D recording on a single charge. Remaining battery time (minutes) is displayed in the electronic viewfinder.
The new DEV-3 and DEV-5 digital recordable binoculars from Sony will be available in November 2011 for about $1400 and $2000, respectively, at http://store.sony.com, Sony retail stores and other authorized retailers nationwide.
