The Angle Finder C lets you adjust the viewing angle while also providing a 1.25x to 2.5x switchable magnification. Provided with built-in variable diopter correction, supplied with Finder Adapters Ec-C Ed-C to fit any EOS camera. Great for more precise focusing. I purchased this for $179, took it out of the box for a look see and never got round to using it as I am using a laptop connection to my camera to focus. This is new, in superb condition. Comes with case, instructions, eyepiece adapters (x2). Sale for CONUS ONLY. Shipping add $7.
