The Vu Filters 52mm Sion Solid ND 0.3 Filterfrom Vu Filters 52mm Sion Solid ND 0.3 Filteris an ND filter with a 2x filter factor that provides a 1 stop exposure reduction. Its 0.3 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to 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.

To prevent internal ghosting and reflections, each glass surface includes seven layers of anti-reflection coating. This multi-coating also offers greater protection to the filter substrate and helps it to stay clean for longer than with uncoated filters. The Flat Wave Overcoat associated with this Sion solid neutral density filter provides an additional eighth layer over the multi-coatings on the front side of the filter, resulting in an improved beading effect to repel water for greater cleaning efficiency.

This Sion solid neutral density filter is constructed from Schott glass for optical clarity as well as color fidelity and features an aluminum-alloy filter ring for durability while remaining lightweight.

Related Questions and Answers

Q: 1. is this filter threaded so that I can screw another filter onto it once it is screwed into the camera lens?

A: No this filter does not have front threads. As a note, it is not recommended with a ten stop filter to use stack filters. The chances of getting flair or color shifts increases by stacking and especially on a ten stop filter.

Q: 2. can I put a Filter on this Filter?

A: Yes. It has a 55mm front thread as well, so you may stack other 55mm threads on top of it. However, for best practices, it's recommended you keep the amount of stacked filters to as little as possible to prevent transmission loss, artefacts such as glare, color-shifting, etc.

Q: 3. Will this ring work on my IRIX 11mm Blackstone for Nikon Lens? ( trying to find a filter system )

A: No, the Vu Filters 150mm Professional Filter Holder 127mm Lens Ring will not fit on the IRIX 11mm f/4 Blackstone Lens for Nikon F. The Irix lens will accept 30 x 30mm cut gel filters at the rear of the lens.

Q: 4. I have a recessed light fixture trim with a built in LED light engine with an output of 840 lumens. This fixture is on the same switch/dimmer system as adjacent LED fixture with a lumen output of 450 lumens. How many layers/filters would I need to get the 840 lumen fixture's output down to the 400/500 lumen range ?

A: ND .03 is 1 stop. 1 stop is 100% more light up or 50% less down. To go from 800 to 400 you would need 1 layer.

Q: 5. can this be fit on a Rokinon 14mm 2.8 lens?

A: Hi, this filter holder is not compatible. For the Rokinon 14mm lens, you would need a dedicated filter holder like this one: https://www.bhphotovideo.com/c/product/1212507-REG/fotodiox_wndpn145_esntlcp_kr14_wonderpana_145_core_unit.html

Q: 6. Is there a place where I can just buy the plastic case shown in pictures?

A: Unfortunately, we dont carry that filter case separately. You could look at the B+W Plastic Filter Case D. It would be able to accommodate a circular filter up to 82mm.

Q: 7. is there a way to use a 82mm circular polarizer for my 17mm ts with this ring?

A: No, there is not. The Vu Filters 150mm Professional Filter Holder Lens Ring for Canon TS-E 17mm f/4L Lens is designed for use with the Vu Filters 150mm Professional Filter Holder, which is designed for use with 150mm-wide square or rectangular filters. There is no adapter ring to connect the smaller 82mm circular filter onto/into the Vu Filters 150mm Professional Filter Holder.

Q: 8. Anyone know if this would vignette on a 16mm on full frame? I primarily shoot a Nikon 16-35 on a D850.

A: This will not vignette on 16-35mm if you do not stack it over UV filter

Q: 9. Hi Do you have the B+W series 7 0.9 ND filter?

A: The nearest option would this 2 stop version: https://bhpho.to/3x5JhyN Series size filters are only made for older lenses so the filter selection will be rather limited.

Q: 10. Will this fit the Rokinon 10mm 2.8?

A: Unfortunately we do not have a ring designed for the Rokinon 10mm f2.8 lens
