Many of the previous speakers criticizing the inflated sales price. Although I see also 16 for a piece of plastic to be unjustified, I prefer no star from it. The lens hood can I compare with the EW-60C (aperture for the kit lens). In this comparison, ET-63 is significantly better. The installation is very easy. You just have to attach the hood to the lens and screw. When Hood EW-60C I had only ever the lens in MF mode set as the focusing unit rotates like. Visually gives the lens hood the 55-250 IS STM lens more value. It sees this (subjectively) more professional. Otherwise, because of the size, the NLENDE has an excellent position as a protection for the lens glass.
