Cat. No. FD-Lens-Cap-III
If you lost your original cap and would like a replacement, here is a lower cost alternative. This is a satin finish metal lens cap with the folding hinge in the middle like the original ones Outside edges and inside are painted black. It's lighter weight metal than the original, made in Asia, but looks quite decent and fits better than some other reproductions I've seen. Price is but a fraction of the originals.
