Geli for zoom

Bin with the purchase of a panel very zufrieden.Zum the product was very fast with me, completely uncomplicated. The attachment to the zoom lens 75-300 worked through existing internal thread is not immediately and canted at first, but it worked at the second attempt and now I've got the hang of it;) A simple plug me if it were rather come to meet. Am glad that I chose for the tulip-shaped bezel, as it just perfectly keeps the side incident light when zoom lens. The image results are sharp and fun on more. I let the shutter now generally on the lens! Can only recommend buying, especially if you are new entrants and many additional items for the camera overwhelm before. Very useful also the cord on snap-on lid, so nothing is lost.
