This useful little accessory moves your standard eyepiece back 15mm for more comfortable viewing. To install simply slip off your Canon eyecup, slide this onto your viewfinder and then put on your eyecup. It will also help to keep your nose clear of the LCD monitor, reducing grease and smears. Compatible with Canon's dioptric correction lenses. This is the mark II version of the extender: the mark I fits most other Canon EOS cameras, with the exception of the 7D series and 1D series.
fits EOS 6D Mark II, 80D, 100D, 200D, 450D, 500D, 550D, 600D, 650D, 700D, 750D, 760D, 1000D, 1100D, 1200D, 1300D.
