Canon's new Angle Finder C is designed for waist-level and low-angle picture taking, as well as copy work and macro photography. Featuring a rubber eyecup and a built-in adjustable diopter, its roof prism keeps the image correctly oriented for easy viewing. Angle Finder C attaches to the viewfinder eyepieces of Canon EOS cameras via two types of supplied adapters, and is even compatible with most manual focus Canon SLRs.
A highly significant new feature is switchable magnification (1.25x or 2.5x). The 1.25x setting shows the entire frame including exposure data outside the picture area, while the 2.5x setting provides a magnified view of the center of the image area - excellent for critical focusing with macro lenses and other specialty optics.
