Product infoZip Box 4x4 holds one 4"x4" (100x100mm) filter and clamps on the front of a lens. Available in two sizes 80-85mm and 90-95mm. The lens shade design allows for even the widest lenses and sensor sizes to be covered without vignetting. Zip Box is extremely lightweight and weighs about the same as a standard filter which makes it perfect for gimbal and drone use. Stainless steel components and unibody rubber design are very durable and stand up to the toughest conditions. It is important to note that you should measure based on outside lens diameter and not based on the threaded filter ring size.
