Magnetic Control System (MCS) is a new line of Tiffen filters launched at NAB this year and come with some tantalising upgrades over the older non-magnetic filters such as 2011's Tiffen 2-8 stop VND filter.
These upgrades include a brand-new magnetic design which allows filters in Tiffen's MCS range to be snapped on and off the front of your lens quickly. The front metal cap is also magnetic so clips on when you’re not shooting. It also claims to have a wider set of ND of strengths, ranging from 1.5-10, an increase from the 2-8 stop range found on Tiffen’s standard VND, though I put these claims to the test in this review and found Tiffen overpromises on this front. It also boasts a sleek, more user-friendly design, a screw-in handle for fine adjustments and hard stops at the extreme ends for haptic feedback so you don't accidentally push the filter past its intended strengths.
