Plastic is not just plastic

This sunshade / GeLi is not suitable for lenses which during focusing turn the lens, here please pick up the original accessories. For my Canon EOS 550D with 18-55mm and 55-250mm the total superfluous, so Canon offers only rings and no tulip shape.

Please keep in mind also, that leaves to be desired processing very left. In theory the Geli but the locking screw and the corresponding thread is not well designed for frequent use.

Would have expected more for the price, now I ordered the original accessories, which even is quality and even cheaper.
