Hoodman Collapsible HoodLoupe / Viewfinder Display Magnifying Loupe / Glare Free Viewing For Canon EOS 5D Mark III, 1D X, 1D C and For All Digital Cameras with 3.2" LCD Screens and a FREE 5 Piece Camera/Camcorder Deluxe Cleaning Kit

I bought this loupe after borrowing one from a friend. This is the best accessory that I own! Highly recommended for getting a good idea of what your photos really look like, and particularly useful in bright, sunny environments.

Really like this item. Have not had much time to use it but it will help see the screen when viewing the pictures and you can adjust the eyepiece to your own eyes.
