This 77mm SLR Magic Variable ND Filter 77mm 1.3-6 Stopis a solid variable neutral density filter that is designed to mount onto lenses with 77mm front filter threads and provides an exposure reduction of 1.3 to 6 stops. The 0.4 to 1.8 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. The degree of density is easily controlled by rotating the front filter ring, helping you to predetermine the additional exposure length required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. For easier, repeatable control over density settings, the front ring is visually demarcated with numbers representing different density values and includes a rotation lever to further enable fast and precise positioning of the front ring. Once the front ring is rotated into a position that corresponds to the desired amount of density, the filter's rear ring can then be turned to lock the front ring into place, helping to ensure consistent exposures.

This filter is constructed from optical glass for clarity and color fidelity. It is multi-coated to prevent internal ghosting as well as reflections.

Variable neutral density filter allows you to dial in differing amounts of density scene to scene.

0.4 to 1.8 neutral density filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.

Providing a reduction of 1.3 to 6 stops, this filter allows you to control depth of field and convey movement more easily.

Offers increased flexibility to use specific ISO settings or ISO films under bright ambient light.

Provides increased exposure flexibility while using cinema or video cameras within a designated film frame rate.

Multi-coated, optical glass for clarity and color fidelity as well as the prevention of internal ghosting and reflections.

Side lever allows the filter glass to be easily rotated.

Integrated exposure locking ring prevents accidental rotation of filter glass and changes to corresponding density values.

Plastic filter case for storage and transport.

Related Questions and Answers

Q: 1. Does this -SLR Magic 8mm f/4 Lens- works on Fuji XT1 camera?

A: The SLR Magic 8mm f/4 Lens has a Micro 4/3 mount, so it cannot fit the Fuji X-T1 directly nor can it be adapted to fit.

Q: 2. Will it fit on the Sony A7R 2?

A: You will need an adapter, and you will be cropping very heavily. The final image will probably be around 12MP.

Q: 3. Will this work with the SLR Magic anamporphot 1.33?

A: The 8 mm is too wide as well as a 15mm wide lens I have tested. Check SLR Magic recommendations as they are pretty true to form.

Q: 4. As it meant for drone & stabilizers, since it is m43, will it work with Blackmagic Pocket Cinema Camera?

A: This will be compatible with the Blackmagic Pocket Cinema camera.

Q: 5. Is this compatible with a LUMIX GX85?

A: Yes, the SLR Magic 8mm f/4 Lens is compatible with the Panasonic GX85 camera.

Q: 6. Will this lens fit the Olympus EM-10 Mark ii?

A: Yes, it is made for any Micro 4/3 mount camera. As long as you can tell the camera to shoot without a lens (no electronic contacts on this lens), the camera won't have an issue.

Q: 7. Can the SLR Magic Achromatic +1.8 Diopter be used on another manufacturers lens e.g. Sirui's new anamorphic 50mm lens to provide closer focusing?

A: The manufacturer makes this to work with his own lenses and doesn't test it on other lenses.

Q: 8. does this lens produce a "hotspot" when using it to create infrared photographs (either with an IR pass filter or IR-converted camera) ? if it does, how noticeable is it and is it only at certain apertures? please send links to sample IR photos if you have any.

A: This lens was not designed with IR shooting in mind.

Q: 9. What kind of lens breathing is there if I want to try photo stacking with this lens?

A: The SLR Magic 8mm f/4 Lens does have visible focus breathing. One can crop to mitigate this effect.

Q: 10. That 52mm filter adapter has glass in it, right? Can I get it out and put 52 to 72 step up adapter on it? Not sure why they put glass...I'm afraid to touch it:)

A: Yes you can just use step up ring
