The PolarPro 77mm Portra filter is a round 77mm warming filter. It attaches to a lens's 77mm front thread and can be stacked with other filters via its own 77mm thread. Additionally, the 77mm Portra features a 16-layer multicoating that minimizes internal ghosting and reflections.
Key Features
Color Enhancing Filter
A color enhancing filter lifts particular hues without a full color cast.
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.
77mm Filter Thread
The filter threads onto a 77mm front thread. A lens with a different thread needs a step ring.
77mm Front Thread
The front of the filter carries its own 77mm thread, so a second filter or a hood can be mounted in front of it.
Warming Cast
The filter carries a warm cast, which holds skin tones under cool or overcast light.
16-Layer Multi-Coating
The glass carries a 16-layer multicoating that minimizes internal ghosting and reflections.
