For my Canon EOS M I ordered this inexpensive screen magnifier. .You Is made of quality plastic and has a large, non-adjustable view Lupe .So you can in direct sunlight the image on the display well recognize .The large eyecup made of soft rubber material adapts to the eye field well and prevents stray light. This is also noticeable in the video films.! A metal frame that is screwed down on the tripod mount holds the magnet body provided with very strong a light, fast and disassemble is therefore guaranteed. It does not need anything to be stuck !!! For fast delivery of Amazon and the solid packaging I give four stars .Also for Macro photography is the part .MAN interesting can better focus. Control of the recordings on the cloth screen is no longer possible with mounted magnifier.
