A front lens cap keeps dust and scrapes off the glass between shots, and it must match the filter thread size printed on the lens barrel. Caps differ in how they grip: center-pinch caps are squeezed in the middle, side-pinch caps at the edges, and brand-fit caps are made for specific lenses.
The six caps below cover 49mm to 77mm sizes. Details come from each listing page. We have not used these caps ourselves, and fit claims are the sellers’ own, so check your lens size before ordering.
