The Tiffen 55mm ND 0.4 filter is a round 55mm neutral density filter. It attaches to a lens's 55mm front thread and can be stacked with other filters via its own 55mm thread. The filter reduces incoming light by about one and a third stops.
Features
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.
55mm Filter Thread
The filter threads onto a 55mm front thread. A lens with a different thread needs a step ring.
55mm Front Thread
The front of the filter carries its own 55mm thread, so a second filter or a hood can be mounted in front of it.
1.3-Stop (ND 0.4) Neutral Density
The filter reduces incoming light by about one and a third stops.
