I have a Canon EF-S 55-250 lens for which I bought an ET-60 Lens Hood. The thing is, unfortunately, very bulky and take up much space in the camera bag. You can not really put good reversed on the lens as well, so had to be something else. This lens hood of Matin is expanded almost exactly in the dimensions as the fixed lens hood, but collapsed significantly less space. And you can always leave it, so I then had this when I need them. In the 55mm lens setting you can use the panel in the first Ausklappstufe, the second stage of 250mm, very practical. The quality is good, rubber stinks not to plasticizers. I am very pleased.
