Canon Lens Dust Cap E Rear Lens Cap for EF and EF-S Lenses

A lens in your bag without a rear cap is asking for trouble: dust, scratches on the rear element and dirty contacts. The genuine Canon Lens Dust Cap E reliably protects the back of your EF and EF-S lenses whenever they are off the camera.

• Genuine Canon Lens Dust Cap E (rear lens cap)
• Fits lenses with EF and EF-S mount
• Protects the rear element and contacts from dust and scratches
• Ideal as a replacement or a spare in your camera bag

Keep your lenses protected

Protection for the rear element

Scratches or dust on the rear element affect image quality far more than on the front. The cap keeps it clean while the lens sits in your backpack or cupboard.

Secure bayonet fit

The cap twists on via the bayonet just like the lens itself, so it stays put while you carry your gear around.

What it looks like in practice

Lens changes on the trail

On a hike you switch between a wide-angle and a telephoto. During a hurried swap the rear cap rolls down the slope. With a spare in your bag the lens is protected again straight away.

What to know before you order

Not for RF or EF-M lenses

The Dust Cap E fits lenses with EF and EF-S mount. RF and EF-M lenses use their own Canon rear caps.

Not a body cap

This cap is for the back of the lens. To close the camera mount you need a body cap.
