This I can do without it, remove after each shooting the lens hood and the lid to attach the original lens cap (49mm). This saves time and means less wear.
The lid has been manufactured in China for good plastic and works as I expect. Build quality and price / performance ratio I rate as very good and would recommend the purchase without limitation. The shop has delivered quickly and without shipping costs.

Meanwhile I use the cover even on my lens Sony SEL18-55mm.
