The LC-SET lens cap fits lens shades 3.5 x 5-inch, 5.5 x 6.5-inch and 6 x 8-inch. This LENS CAP is hard to misplace. There is a quick connect buckle and tether to keep it tied to the zoom control strap, camera handle or your own belt loop. The white balance panel gives it structure and inside is a slip pocket for lens cleaning tissue and business cards.
