I knew there was an extender out there somewhere that I was wanting (not some pop-up), and I looked in my Canon Book and in the back was the extender that I was looking for... It even gave the part #...  EP-EX15    I had been looking for a long time, but decided to use the part # and viola!  Found it on Ebay... purchased it and it is wonderful!!! 

No more having my nose smashed up on the LCD screen, and having to wipe the screen often.  It's great... Love It!  Glad I bought it!

You simply remove your existing Eyepeice, slide the new one in place, and then, slide your existing eyepeice in front of the new one... It's Awesome!
