Query: Landscape and Commercial Photography

The grid screen is a "must have" for the photographers that shoot strong lines and landscapes. The grids are not only helpful in composition, but make stitching panorama's a breeze. Use the Ee-D for the Canon 5D and the Ec-d for the 1D MkIII. You won't be disappointed. BTW, installation is breeze.
