Cokin P121M Gradual Grey G2 Medium ND4 Filter

Cokin graduated ND filters are just the ticket for landscapes where the sky is particularly bright -and thus susceptible to being over-exposed - or when you want a darker, moodier sky. The filter retains normal colour balance across the visible spectrum, with a progressive graduation from the middle to the top of the filter. For those familiar with the Cokin line, the P121M filter has the same colour as the 121 filter, but a lower tone.

How the Cokin System works

The Cokin Creative Filter System consists of three main components: A filter holder / Adapter ring and a Filter.

1. Screw the adapter ring onto your lens.

2. Slide the filter holder on the adapter ring until it snaps in place. The filter holder is now solidly attached to the lens, yet it can rotate both left and right.

3. Slide the filter into one of the filter holder slots. The one closest to the filter holder housing is the narrowest; it allows the use of round filters with notched edges (polarizer, star filters..). The two central slots are intended for square filters. The outer slot can be used either for an additional filter or for a coupling ring.
