Cokin Z-Series Hard-Edge Graduated ND 0.6 Filter

This 100mm by 150mm filter darkens bright skies by two stops while leaving the foreground untouched. The hard transition line suits horizons with a clear, straight edge. C39 optical resin construction maintains colour neutrality across the frame. It slides into the Cokin Z-series holder for quick adjustments.

Landscape photographers balancing exposure

Photographers who need a soft, feathered transition for mountains or trees should choose a different graduation type. Video shooters requiring variable density control will not find it here. The fixed two-stop density cannot be adjusted for changing light. Users of smaller filter systems need a matching holder first.

Hard-edge graduation with two-stop density

The abrupt transition line is the single specification that decides fit. It matches flat horizons such as oceans or prairies perfectly. Uneven skylines will show a visible dividing line in the image. Choose this filter only when the horizon is straight and the exposure difference is roughly two stops.

Questions about this item

How do I mount the Cokin Z121M G2 100 x 150 mm filter on my lens?

Insert the filter into the Z-series holder slots with the graduated edge oriented toward the bright sky, then tighten the holder's locking screw to prevent the 1.6 mm resin plate from shifting during composition.

Will the C39 optical resin surface of the Z121M G2 degrade or need replacement over time?

The resin resists yellowing, but deep scratches cannot be polished out; replace the filter if the hard-edge transition shows visible damage that affects the 2-stop density line.

At what point does the hard-edge transition of the Z121M G2 become visible in long exposures?

The abrupt graduation line can appear as a hard band across the frame when the horizon is not perfectly straight or when the 0.6 density transition aligns with scene detail during extended exposures.
