This 5-stop, 72mm Kolari Vision Pro IRND Filter is optically engineered to be the most neutral filter in the visible light spectrum and beyond into the infrared range. This filter delivers neutral darkening in every wavelength, and at every angle. Ultra-wide angle tested and approved for excellent vignetting and color cast performance. Built with premium ultra-thin, ultra-strong Corning Gorilla Glass, this filter is more than two times stronger than Schott B270 glass to direct impacts, and more resistant to scratches for better long-term durability. The slim-brass frame features knurling that helps with your grip, making it easier to attach and remove the filter.

Related Questions and Answers

Q: 1. Anyone having issues using lens caps and this filter? Can you share what lens cap you're using on top of this?

A: I use the lens cap that came with the filter, and it works quiet well - it's a slip-on, but seems to stay without any issues.

Q: 2. is the 67mm version front threaded? what's the size? want to fit my lens cap

A: It is front threaded. The front thread is 72 mm. The front thread is written under the Specs tab in the section that says Front Accessory Thread.

Q: 3. Does this filter work with an M.Zuiko Olympus F2.8 Pro 12-40mm?And would a step down ring 52-62mm cause vignetting?

A: It will work with that lens. If your using a 52-62mm step up ring from a smaller lens you will be ok. If your using a step down to put a 52mm filter on a 62mm lens then you will most likely have vignetting.

Q: 4. Does this vignette on the tokina 11-20mm 2.8?

A: No there will be no vignetting when using the B+W 82mm XS-Pro Digital ND Vario MRC-Nano Filter. XS-PRO filters are designed with a thinner ring so they can avoid vignetting on a wide angle lens.

Q: 5. with an ultra-wide angle lens (i.e. Canon 16-35mm F4L with a full frame camera), do you get the dreaded X show up and if so at what density does it show up?

A: The X you can sometimes pick up in the image with a variable ND filter is caused most of the time by variable ND filters that go over 7-8 stops and lower quality ones.The B+W filter is fine. The one thing you might pick up is when set to the widest setting on that lens, 16mm you might pick up some vignette. And that is going to happen with that lens with most filters because of how wide it can go. The filter is designed with a thinner frame so it should be somewhat minimal.

Q: 6. This filter has a 72mm filter thread. So, is it same to assume that a lens cap will also be 72mm?

A: That's correct, Lenscap is 72mm. This filter lives on my camera almost permanently. Worth every cent!

Q: 7. Does the front filter thread rotate when changing ND Amount? Looking to add a step up ring and go to a matte box.

A: Yes, the front threads on this filter are a 86mm size.

Q: 8. What is the widest focal length this can be used on with no vignetting?

A: I have the filter on my 24-70mm/f2.8 lens. So the widest is 24mm. I did not see any vignetting. I am very happy with this filter.

Q: 9. Does it come with a lens cap?

A: No it does not. I purchased an 82mm one separately.

Q: 10. Can I use this on my Nikon wide-angle lens 10-24mm without vignette?

A: Most likely, no. The rim on this filter being the variable midel, is much wider than a standard ND would be. You definitely need to find a fixed stop ND for a wide angle. Even with that, you may still have slight vignetting at the 10mm end.
