Unlike lesser binoculars with fixed focus cameras, these 8X magnification binoculars use special focusing technology that sharpens subjects simultaneously on its integrated 5 megapixel digital camera, ensuring clear images and video. They have fully multi-coated, 30mm objective lenses and use a Bak-4 prism system for superior optical performance, yielding a 320' field of view at 1,000 yards. The eye relief allows them to be used while wearing glasses. Once you've taken a photo, it's easy to review pictures on the 1 1/2" color flip-up LCD. Its replay feature continuously records the last eight to 60 seconds of video, so you can review footage to capture a photograph of quick, precise events. The built-in 16 MB internal memory stores up to 15 pictures at 2560 x 1920 resolution or 20 seconds of continuous video at 640 x 480 resolution at 15 frames per second. An SD card provides for added storage (card not included). Photos and video can be downloaded to your PC via an included USB cable. Requires two AAA batteries. 4 1/4" H x 6" W x 3 1/4" L. (1 1/2 lbs.)
