which was claimed here that would not GeLi bayonet lock, I can neither understand nor confirm. Of course, the bayonet lock is present, at the beginning it is a bit heavier than normal (perfectly normal!). Just set up and 90 ° (the label "JJC" is then above), already sits GeLi perfectly on the lens. A naturally opposed touchdown, fits in your camera bag is also possible.
Unlike the original JJC offers the optimized tulip shape here, which develops the maximum possible protection. In addition, these GeLi is here still clearly cheaper than the original linear and preferable in my opinion thus.
