A perfect replacement for the Canon T90. It clips-on and won't fall off.
This was a replacement part and worked perfect on my Cannon. I was quite pleased that this part was easily available and reasonably priced.
The price [...]
The Canon EF eyecup keeps working itself loose on my XTi and has disappeared at the most inconvenient times. That wouldn't be a problem if it were a [$], but for the price I'd expect it to do a better job of staying attached. I'm now here ordering more backup replacements as I'm on my third one. I love Canon but they really dropped the ball on this minor part.
Since I lost the original eye-piece somewhere, I wanted to replace it. I wear either sunglasses or regular glasses, so i needed the cushion to help view the scene thru the camera.
Product does just that.
