EW-54 Replacement Lens Hood
for Canon EOS M EF-M 18-55mm F3.5-5.6 IS STM

Product Description

Lens hoods are primarily designed to prevent unwanted stray light from entering the lens by extending and shading the end of the lens

In addition, since the end of the lens is extended you also get the added benefit of some extra protection from accidental impact
