Canon E-67II Lens Cap

The Canon E-67II Lens Cap is designed to fit on any lens with a 67mm filter thread. The pinch-in snap on lens cap is an indispensable accessory and is a replacement front lens cap for lenses such as the Canon EF-S 18-135mm f3.5-5.6 IS and Canon EF-S 17-85mm f4-5.6 IS USM. It's always handy to have a spare around, too.
