The Hoodman 3” Hoodloupe fits exactly over the 3” screen of most recent LiveView and video-enabled DSLR cameras, and provides glare-free viewing outdoors. It attaches to the camera via the Hoodman Cinema Strap, which keeps it securely in place. The Hoodloupe has a +/-3 dioptre compensation and focusses just like a binocular eyepiece - the eyepiece turns left or right to adjust for your eyesight. The price is £75.99 for the Hoodloupe and £18.99 for the Cinema Strap. Both are available from Newpro UK.
