When the ultra-wide-angle lens uses the front-end filter, many landscape photographers complained, the camera + super wide-angle lens + scenery essential filter + various photographic equipment, they are too heavy! I want to reduce the burden, but I can't give up any!

Having multiple filters for multiple lenses, especially if those are with a different diameter can be a major pain sometimes. Losing step-up rings are quite easy and even permanently attaching them to the front of a lens that doesn't solve the problem too, so a filter suitable for all of your adapted lenses are urgently needed.

Reform is imperative! Kase introduces a new rear-mounted filter that is small in size and portability, and is mounted on the rear of the lens with a neutral density filter to prevent 100% light leakage.
