The 4 x 4" Cavision Enhanced Range ND Filter has a filter factor of 8x that provides a 3-stop exposure reduction and is compatible with filter holders that can accommodate 3mm thick rectangular filters. Its 0.9 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By increasing your aperture or slowing your exposure time, you can control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

This filter is uncoated and is constructed from optical glass for clarity as well as color fidelity. Its enhanced range design is intended to maintain image sharpness when used with lenses that feature a focal length of up to 300mm.

Q: 8. Will this work properly on a Leica 50mm Noctilux f/0.95?

A: Yes, the 60mm Heliopan variable ND filter attaches directly to the Leica 50mm Noctilux f/0.95. It is a great quality filter and easy to use. It is good not to need a step up ring and you can extend the built in Noctilux lens hood over the filter. However, same as BW filter, you can't use the Leica noctilux lens cap directly on it.

Q: 9. Am I right to assume that a 58mm lens cap would fit over this filter?

A: Yes, technically a 58mm lens cap should fit. But filters like these can be wider. They essentially are made up of two polarizing filters sandwiched together. So they can be a bit wider because of that.

Q: 10. 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.
