I can see the article! My nose is no longer dependent on my camera screen constantly. That and the resulting grease spot was what annoyed me most. The viewfinder image is indeed slightly reduced, but does not bother me. The advantage of this way: The viewfinder display with all its digital impressions is to survey faster. :-)
Addendum: After four months of use, I am completely satisfied! I would definitely buy the product again! +++ I use the Extender the way to a Canon EOS 70D!
