Who does not know the problem of eternal lack of space in the camera bag ...... sun visor or .. "Gelis" have been with! . But unfortunately the stiff Gelis metal and plastic are me sometimes simply too unwieldy and too bulky !! Therefore I ordered from Amazon Rubber Sun visors in various sizes .. .You are solid made of good rubber material and act but not cheap - No müffelnder Chemical smell !! They can be easily screw on to the lens and "fold back" in three stages. And deliver them into the narrow Fototasche sometimes "after .-" DH squeeze, -but not lose their function or form. For the price all OK. Also fast delivery and solid packaging .Therefore full star.
