The Canon EP-EX15 Eyepiece Extender extends the eyepiece by 5/8" (15mm)
from the camera body and reduces the viewfinder magnification by 30%.
This is useful for eyeglass wearers and others who wish to prevent the
tip of their nose from touching the camera body. It also prevents
condensation or fogging.
The EP-EX15 fits the following Canon EOS cameras: Digital Rebel,
Digital Rebel XT, Digital Rebel XTi, 1D, 1D Mark II, 1D Mark II N, 1Ds,
1Ds Mark II, 1V, 20D, 20Da, 30D, 40D, 5D, 6D, D30, D60, EOS 3, IX LITE,
Rebel 2000, Rebel G, Rebel G II, Rebel K2, Rebel T2, Rebel TI
