This 2-stop, 49mm 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. What's the most popular diopter number?

A: There is no specific diopter number as it depends on the lens. But many do want more magnification. So in the kit, Hoya 49mm HMC Close-Up Filter Set II (+1, +2, and +4) it would be the +4.

Q: 2. Will this fit the Sony Zeiss 55m 1.8 full frame?

A: Yes, it will fit.

Q: 3. why is the 49mm center pinch lens cap a recommended accessory for this lens hood? I bought the hood and took B&H advice and purchased the 49mm cap. Doesn't fit. The appropriate cap for this hood is the 58mm cap.

A: Yes... 49mm is the lens filter / cap size. Leaving the hood on, to cap the lens you would need a pinch type.

Q: 4. Can this variable B+W ND be stacked with a B+W ND 10-Stop filter in order to achieve a 13-15 Stop result?

A: Yes, but shooting thru several pieces of glass will reduce image quality.

Q: 5. Will this fit Zeiss Batis 67mm lens with the hood ON?

A: I would say most likely no as I cannot use a hood with any of my lenses when using this filter.

Q: 6. Is this a hard stop filter where it goes from 2 to 5 and then it can't proceed further ?

A: The rotation of the filter is smooth. It does not click as you rotate it. It also stops rotating once you reach the maximum or minimum density.

Q: 7. Can this lens hood be reversed ? J. Payne

A: Unfortunately, screw-in lens hoods cannot be reversed. Typically, that is a mechanism of bayonet-style lens hoods.

Q: 8. who had tried this lens hood on the Sony Sonnar FE 35mm f/2.8 with UV filter attached?

A: The ansnwer is dependent on whatever camera is being used. The Sensei PRO 49mm Aluminum Lens Hood B&H # SELHM49 is for 50mm or longer focal length lenses on full frame cameras. As such, this hood will vignette. On an APS-C sensor camera, it has good chance of not vignetting even if used with a filter.

Q: 9. How thick is this filter?

A: I don't have this filter. Not sure why I was asked by BH to answer the question. Sorry.

Q: 10. Will this work for a 6 x 4.5 medium format 60mm (@35 in 35mm format)???

A: If the lens has a 49mm front thread the hood will fit. But chances are you will get some vignette on the edges of the frame.
