Introduction: The LCD Viewfinder is consisted of Anti reflective coated 2.8X magnifying lens, Soft rubber eye cup, plastic barrel, and magnetic LCD screen mount. When mounting on LCD display of a Digital SLR, you can achieve more accurate focus and increase stability of handheld shooting. It also can be used by photographers who want to block out light while shooting in Live View mode or to inspect pictures on the LCD display. The LCD viewfinder allows you to put your eye right up to it, similar to the way you would on a professional camcorder. It also prevents light from hitting the screen, alone making the LCD screen much more usable. This viewfinder allows videographers to shoot outdoors under the bright sunlight which has been a huge problem as glare makes LCD screen very difficult to use when making movies in the afternoon in sunny areas. The LCD viewfinder uses four small magnets connecting with a metal frame that using unique adhesive connects it to the camera. The power of these magnets is strong enough to hold the loupe against the frame and camera Suitable for: V1(4:3) Canon EOS 7D 500D 450D 40D 50D 1DS 5D Mark Ⅲ / II Nikon D7000 D300S D700 D600 D800 D3 D3X Other 3.0": G12、G15、G1X、LX3、GF1 Pentax KR......
