The Schneider Compact ND Kit for 114mm-Diameter Lenses contains three 4.5" round drop-in solid neutral density filters and a 4.5" round filter holder that is specifically designed for 114mm-diameter lenses without front filter threads. This kit is ideally suited to cine lenses, such as the Zeiss CP.2 and Canon Cinema EOS Primes, and serves as a more compact, streamlined method for using filters with these larger lenses when compared to a standard matte box.
