A very common occurrence in digital photography is the quality of the final digital image not matching the image you see on the back of your DSLR’s LCD screen. While LCD screen sizes are at a maximum of about 3 inches, you still do not know for certain if your image is properly focused or has any symptoms of camera shake (in low light circumstances). The Hoodman Professional LCD Screen Loupe provides 2x (two times) magnification for your camera’s LCD to confirm focus detail.
