What is included in the kit?
The kit includes three filters: a Gradual ND2 (P121L), a Gradual ND4 (P121M), and a Gradual ND8 (P121S), along with a P Series (M-Size) filter holder.
Are adapter rings included?
No, adapter rings are not included. You must purchase a separate P Series adapter ring to fit your specific lens thread size.
What are the main uses for these filters?
They are primarily used in landscape photography to balance exposure between a bright sky and a darker foreground, reducing contrast and preserving detail in both areas.
What is the difference between hard-edged and soft-edged transitions?
A hard-edged transition has a more defined line between the dark and clear areas, suitable for distinct horizons like a seascape. A soft-edged transition has a gradual blend, better for uneven skylines like mountains or trees.
How do I choose which filter density to use?
Measure the exposure difference in stops between the bright area (e.g., sky) and the dark area (e.g., foreground). Use an ND2 for a 1-stop difference, ND4 for 2 stops, and ND8 for 3 stops.
Can these filters be used with any lens?
They can be used with any lens that has a compatible P Series adapter ring. The filter holder attaches to the adapter ring, which screws onto the lens filter thread.
Do the filters affect colour balance?
No, they are neutral density filters designed to reduce light transmission without introducing a colour cast, maintaining normal colour balance across the spectrum.
