Up until rather recently my photography focus had been centered soley on landscape imagery. The best landscape images are found in the "golden hours" - about one hour before/after sunrise and about one hour before/after sunset. During those times, it isn't at all difficult to monitor your camera LCD for exposure and composition. When you find yourself shooting in bright daylight, however, consulting the LCD is not as easy. This is where the Hoodman Loupe 3.0 can become a valuable addition to your gear bag.
It features a 3 inch loupe to cover your LCD and an eye piece complete with adjustable diopter for personalizing the focus to match your vision. It also includes a lanyard and can be worn around your neck for convenience and a nice zipper carrying case for storage in your gear bag.
Simple concept. Big help when shooting on those bright, sunny days.
