This 52mm SLR Magic Self-Locking Variable ND Filter is a solid variable neutral density filter that is designed to mount onto lenses with 52mm 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.

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. Is this a fisheye lens?

A: The SLR Magic 8mm f/4 Lens is a wide-angle but not a fisheye lens. This lens has a 108° angle of view, while a fisheye lens has a 180° angle of view.

Q: 3. How do I put on a 52mm filter? I can't figure out how to remove the glass on the adapter.

A: To use a 52mm filter with the SLR Magic 8mm f/4 Lens, screw the filter adapter into the front of the lens--the front of the filter adapter has a 52mm filter thread.

Q: 4. This lens will work with a Lumix G7?

A: It will work but it should be used as a lens for video.

Q: 5. 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: 6. Has anyone compared this lens with the Kowa 6mm f1.8 C-Mount?

A: The SLR Magic 8mm f/4 looks like a modified C-Mount lens but the Kowa 6mm f/1.8 has a wider field of view and is sharper.

Q: 7. 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

Q: 8. 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: 9. Does this work with the DJI X5S? Any suggestions which balancing ring is required to work with DJI X5S?

A: May need to add another 52mm weight to balance

Q: 10. 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.
