Made of premium high-strength, heat-resistant polymer with stainless steel hardware, this Front Lens Cap from Bioluminous is a snap-on black lens cap with black locking grips made specifically for the Canon EF 600mm f/4 I.S. lens. The lens cap construction is rugged and durable, and the spring-loaded release tabs are designed to be large enough so that you mount and remove the lens cap while wearing gloves. The cap is a snug fit on your lens and can be mounted on the lens with or without the lens hood attached, even if the hood is attached reversed.
