I have always been annoyed me after every use my Canon EOS 40 D on the nose and face prints on the LCD display. I have it even specially packed a microfiber cloth in the bag. With the newly designed eyepiece Canon EP-EX 15 this is now water under the bridge. One has the right distance from the display and both with the eye, as well as with the spectacles, the viewfinder image better view. The LCD info display in the viewfinder is much better to be recognized by the extension. I do not want to miss the part and give 5 stars and an absolute buy recommendation!
