Impeccable, no difference from the original

For this reason I decided for JJC alternative and I was not disappointed. Super processing, very stable and has a very high quality. The aspect that the panel is a bit difficult to assemble, I think - on the contrary to the other reviews - very good because, conversely, the heavy of assembly also means that the panel is definitely not solve itself from the lens. When GeLi of my 15-85mm the opposite is true and the GeLi strikes me is that is exactly contrary flown every few minutes. Therefore clear advantage for JJC.

All in all more than clear buy recommendation, and anyone who has opted for the expensive Canon is angry when he thinks the time GeLi of JJC in hand.
