Bioluminous Front Lens Cap for Canon EF 300mm f/2.8 Non-I.S. (Red and Black)

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 red locking grips made specifically for the Canon EF 300mm f/2.8 Non-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 without, or with the lens hood attached, even if the hood is attached reversed.
