This lens cap is for optical instrument (eg. binoculars, telescopes and spotting scopes).

Internal Diameter: 77mm (Note: the size is measured as internal diameter of the cap, which is equivalent to the external diameter of the lens including the lens housing).

Depth: 22mm

Material: Rubber.


This listing is for ONE lens cap as described above (not for a pair).

This lens cap is made of rubber material which is flexible, and there are ribs / ridges around the inner rim of the cap. These features enable the cap to fit lenses with external hood diameter from around 75/76mm up to to 78mm. If the cap is a little too big for the hood, you can consider lining the inner rim of the cap with some tape or foam to make it stay on better.

Note: The size of the lens cap is measured as Internal Diameter of the cap, which is equivalent to the external diameter of the lens including lens housing (as shown in the picture above). Please allow a small difference in measurement (eg. 0.5-1mm). A rubber cap can normally fit a slightly bigger lens than the specified size (eg. +1mm to 2mm depending on actual size).

If a cap is slightly bigger than the external diameter of the lens housing and there is no matched cap size available for the lens, you may consider putting an adhesive cloth tape around the internal edge/rim of the cap. This can often secure the cap on the lens.
