The Tiffen 67mm ND 0.9 (3-Stop) filter is a round 67mm neutral density filter. It attaches to a lens's 67mm front thread and can be stacked with other filters via its own 67mm thread. The filter reduces incoming light by 3 stops, allowing a wider aperture or a slower shutter in bright conditions.
Key Features
Neutral Density Filter
A neutral density filter cuts the light reaching the sensor without shifting color, so exposure can be set by aperture and shutter rather than by light level.
Round Screw-In Format
The filter threads directly onto the front of a lens, which suits handheld and location work where a matte box would be in the way.
67mm Filter Thread
The filter threads onto a 67mm front thread. A lens with a different thread needs a step ring.
67mm Front Thread
The front of the filter carries its own 67mm thread, so a second filter or a hood can be mounted in front of it.
3-Stop (ND8) Neutral Density
The filter reduces incoming light by 3 stops, allowing a wider aperture or a slower shutter in bright conditions.
