This 6-stop, 77mm 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.

Q: 1. Would this fit the Tamron 70-200mm F/2.8 USD VC SP?

A: I do not own this particular Tamron lens. The specs on the B&H website say that it takes a 77 mm filter, so this should work just fine. These screw-on hoods work well with circular polarizers or variable ND filters. I use mine on both my Canon 70-200 f4 and my 100-400 II. Hope this helps.
