So I feel neither a noticeable enlargement still a relief to focus the camera. Imagination is also just 'ne education. But what I clearly feel, is an improved distance from the camera. I glue no longer so inclined at the peephole. You can really better and more relaxed look through the viewfinder. The viewfinder would have from me can still be a bit cantilevered. Who wears a proper face bay window to know what I mean. In addition, smeared by the reduced skin contact my LCD display is no longer as strong. Because I have combination skin ;-) Who 'have a real viewfinder needed (factor 1.5 to 3!) Of the concerned's for the same money' nen Winkelsucher here at Amazon. The really brings enlargement and because the olfactory bulb camera distance is really big then, he can even put 'ne red Pappnase Manual focus! Oh yes, although I could use the Live View mode's screen, but I have the snapping "no mood for watching TV"! And another thing (... then is but really end - honest!): Many cameras have an autofocus - really true! And who must necessarily focusing manually with its recycled glass, for which there is to facilitate the ultimate Super-Tool. It's called - glasses - (... But there's not Canon or Nikon ;-))
