The 52mm Sion Solid Neutral Density 0.3 Filter from Vu Filters is 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. does this kit come with a filter holder?

A: It does not.

Q: 2. 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: 3. How does the VU compare with the B+W?

A: Both brands are rated very high as filters go. And within each brand there are ones that are multi-coated and not. In general it is important that a filter be multi-coated. That helps limit flair. Optically they again are very good but some prefer B+W over the other. And just a note that the specific Vu filter does not have front threads.

Q: 4. If I got these filters for the bmpcc 4k, would I need to use an IR cut filter with them or do these filters already cut IR to prevent color shifting?

A: NiSi states that the filters in the NiSi 100 x 100mm Solid Neutral Density Extreme Filter Kit use their IR technology, i.e. the coating that blocks infrared light, and therefore eliminates the risk of magenta color cast.

Q: 5. does it matter which way the filter faces when I use it? (trying to manage gasket vs. my holder)

A: Yes, when using the NiSi 100 x 100mm Solid Neutral Density Long-Exposure Filter Kit (3, 6, 10-Stop) the light-blocking gaskets should face towards the lens.

Q: 6. I have been into photography for a long time but never used filters. Will this kit be too overwhelming for a beginner? Should I be just getting one individual filter than a set like this?

A: If you are ready to start using ND filters this kit is a lot more fun than using thread in filters. The image quality you will obtain is also superior compared to the quality you obtained using a thread invariable ND filter. The system is very easy to assemble and connect to your lenses.

Q: 7. Will these work with the smallrig lightweight carbon fiber matte box (#2660)?

A: Yes, these standard thickness filters can be used with the SmallRig matte box.

Q: 8. 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: 9. 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: 10. This comes with some foam gaskets but don't the filters already have these attached? If so, what's the point of including extras.

A: Those are replacement foam gaskets in case the others wear out.
