I bought the product because I was tired of permanently settle in photographing the original lens cover with my camera and put in the camera bag. I am completely satisfied with it! I use it with my larger zoom lens 100 mm long and have still room for maneuver. Merely attaching the cord in the eye was a little awkward because it is very small. But with the help of a thin floral wire (tip: from a Gerbera) it worked after a few tries. Therefore, only four stars.
