The Freewell ND4 filter is an excellent choice for photographers and filmmakers who need to subtly shorten exposure without losing color fidelity. The 2 EV light reduction lets you work with longer shutter speeds or a wider aperture, while True Color technology eliminates unwanted color shift.
Thanks to the Real Locking system, installation is exceptionally fast—you simply snap the filter onto the L1 base ring or onto a Real Locking VND/CPL lens. The mounting is firm and stable, so you can flexibly change your setup according to lighting conditions.
