This 3-stop, 55mm Heliopan 55mm ND Filter - 3 Stop Filtrationprovides a 3-stop exposure reduction. Its 0.9 optical density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overexposing your image. By slowing your exposure time, you can create motion blur for special effects or to convey a sense of movement. Opening your iris allows you to create shallow depth of field, which can help isolate your subject. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

To prevent internal ghosting and reflections, each glass surface includes four layers of anti-reflection coating. Together, these eight coatings offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters.

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

Related Questions and Answers

Q: 1. 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: 2. What if live view is used?

A: To my original answer, I should add that on a Leica M, the EXIF data will probably show a different aperture to the one on the lens.The Ms have no electrical connection between camera body and lens, so the camera infers aperture for EXIF by comparing light intensity metered at the shutter compared to the ambient light on the body. (That's what the small light meter hole on the front top of the body is for.)

Q: 3. Can this filter be safely used as a solar filter to film the upcoming solar eclipse?

Q: 9. I was hoping to use this for solar photography but I want to be safe. Is it safe to look at the sun through a Nikon d750's viewfinder with this filter? If it's not safe for me is it safe for the camera? - (eg could I use live view instead of looking through the viewfinder)

A: You can look at the sun with this filter, but taking precautions is always good. Start out by using sunglasses at first, look through as see, then without and compare, if it is comfortable you know its ok.Ive shot images of the sun looking directly though the viewfinder without issues using this filter

Q: 10. What are the meaning of the numbers from 1 to 12 on the filter? Can I use it to adjust an exact ND stop like ND8 or ND16?

A: The 1-12 scale is a half-stop scale that allows you to more precisely set the filter to 0.3 (1-stop) through 1.8 (6 stop) increments, as well as halfway in between any of those stops. It is not exactly related to ND8 or ND16 stops as those would be 0.9 (3-stops) and 1.2 (4-stops), though you could use this 1-12 scale to set those at numbers 6 and 8.
