The 49mm Sion Solid Neutral Density 0.6 Filter from Vu Filters is an ND filter with a 4x filter factor that provides a 2 stop exposure reduction. Its 0.6 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.

Q: 1. Will this work on Sony 24mm GM with lens hood?

A: You can use this filter with the hood but rotating it would be a task.

Q: 2. Has anyone used it on an ultra-wide like the Sony 16-35 2.8? I'm worried how it will perform when ultra-wide.

A: The Polarpro filters are excellent and should produce high quality images without any vignetting on the wide end.

Q: 3. Can you take the polarizer off without unscrewing the holding brackets!?

A: You must remove the brackets in order to mount or remove the Polarizer filter.

Q: 4. do the filter eliminate IR pollution?

A: No, that filter does not reduce IR pollution. It is a Variable Neutral Density filter. The filter only reduces the amount of all light getting through.

Q: 5. Does this VND also have polarizer built in.... or should we consider getting the PolarPro fixed ND/PL? Thank you

A: This filter is only a VND, if you want a combo, then the Polarpro ND/CP would be the way to go.

Q: 6. Is it same the polarizer that comes with Vu Filters 150mm Filter Holder and Sion Circular Polarizer Kit ?

A: No it is not. The polarizer from the VFHSCPOL150 is a specially designed optic for the VFH150. The 105mm Sion Circular Polarizer is a standard 105mm threaded filter for lenses with 105mm threads

Q: 7. Does this have 82mm threads on the front to attach a lens hood?

A: This filter does not have front threads.

Q: 8. 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: 9. How is this installed?

A: You can use gaff tape https://bhpho.to/3353R3h.
