Kase Rear Filters for Canon EF 11-24mm f/4L & 14mm f/2.8L

Kase Rear Filters for Canon EF 11-24mm f/4L &14mm f/2.8L is an ND filter set specifically designed to mount on the rear of the lens (rear mount) for ultra-wide angle lenses such as Canon EF 11-24mm f/4L USM and Canon EF 14mm f/2.8L II USM.This design makes it easy for users to use filters even with lenses with convex front lenses, which cannot install conventional threaded filters.

ND (Neutral Density) filters help reduce the amount of light entering the sensor, allowing photographers to use slower shutter speeds or larger apertures in bright light conditions.This is especially useful when shooting landscapes, long exposures, shooting videos, or creating moving effects of water and clouds.

The filter is made from toughened optical glass with multi-coated to help reduce reflections, limit flare and ghosting, and keep the image's color neutral.In addition, the coating also helps scratch, water and oil resistance, making cleaning the filter easier.

Thanks to its compact design and mounting on the back of the lens, the Kase Rear Filter system saves space in the camera bag and is more convenient than large filter holder systems in front of the lens.
