The Heliopan 77mm #22 Orange Filter is a basic contrast filter, primarily for use with black and white film, that strongly darkens blues and greens, increases overall contrast, and is often used for outdoor photography to emphasize contrast and shadows. It is also well-suited for decreasing atmospheric haze when photographing with long lenses and to smooth skin tones for portraiture. There is an approximate 4x filter factor with this filter, requiring an increase of 2 stops for normal exposure.

The front and rear surfaces of the filter both feature a single anti-reflection coating. Each coating helps to increase light transmission by reducing reflections, scattered light, and ghosting. Additionally, they offer protection to the filter substrate while helping to keep the glass clean for longer than uncoated glass.

This Heliopan filter is constructed from Schott glass for increased optical clarity and color fidelity. It features a brass filter ring for durability as well as jamming prevention.

A: Unfortunately, this filter cannot be disassembled.

Q: 7. The standard is for a #22 filter to need a +2-stop correction. But this offering by Lee specifies a 1-stop correction only?

A: Filters have different filter factors, this filter optimizes light transmittance that allows for only a 1 stop correction.

Q: 8. Does this filter have hard stops? Will it be OK for video use?

A: This filter does not have hard stops but turns smoothly. I have not tried it for video but believe it would apply appropriately.

Q: 9. What's the actual filter weight (not package shipping weight) in grams. Looking for options for drone lens...?

A: Sorry, we do not have the actual weight on record and we cannot weigh it. I would subtract a few ounces to get at the weight you need to know.

Q: 10. How is the 'protection' capability of this lens, if I'm looking to replace my protection/UV filters with this one? And does it have 8 coatings, or one on each side? I've heard conflicting descriptions.

A: The filter has one coating per side to help with reflections and protection of the glass.
