Ok considering the price. The quality is there, but the whole "whines" a little. Given the lens on which the price is fixed, it pays only on trust him: I served for attaching the camera to a tripod / monopod, but I will not go until the lug holding it there. I expected a clip system + Clamp, but in fact there is a screw: Be careful when maneuvering do not unscrew too because I do not know if this is unlikely to completely release the objective and therefore even fall ... The inner foam leaves a slight mark on was the objective, but it can be easily cleaned.
The color is not exactly that of the Canon lens, although very close.
I guess the official accessory Canon (whose price is around 150 !!!!!) it should be much better and put more confidence ....
