Kase Clip-in ND16 Filter for Sony Full-Frame Cameras provides 4 stops of exposure reduction,allowing for finer control of aperture and shutter speeds to compose the desired level of depth of field or motion blur. The Clip-in Filter is installed in front of the photosensitive element (CMOS) of the camera body without affecting the operation and use of the photosensitive element, lens or adapter mount.It is a filter as well as your CMOS protector. Many wide-angle lenses and super-telephoto lenses cannot attach traditional filters to front filter rings. This clip-in filter solves that challenge by mounting inside the camera body, in front of the image sensor. Lightweight & Universal compatibility The clip-in filters are very light in weight,it is only 3.3g. It’s a good way to lighten the weight of your backpack. The filter is installed in your camera.You could shoot with all your lens( telephoto zoom lens, super wide angle lens or fish eye lens). HD Image & Shock Resistant The clip-in filter is made from B270 optical glass, with multilayer coating to ensure beautiful and high-contrast images. The glass is shock resistant. It avoids breakage in the camera when you install. And adds more durability in daily use.
