The 590nm, 72mm Kolari Vision Pro Gen 3 Infrared Lens Filter is fitted with precision machined brass rings, enhanced grip, and a superior lifetime warrantied construction while maintaining a low profile over your lens. This external infrared filter is perfect for adding to a full-spectrum conversion or on top of another infrared conversion to get a different effect. The filter features a hydrophobic AR coating that increases scratch resistance and causes dust, smudges, fingerprints, water, and even permanent marker to slide right off its surface with minimal effort. The brass ring construction features front and rear threading and an aggressive grip knurling for easier filter removal.

Q: 1. Will the 72mm hood work on Fuji 10-24mm?

A: Yes. BUt would highly suggest the following to avoid vignetting issues. Sensei 72mm Wide Angle Rubber Lens Hood BH #SELHRW72 • MFR #LHR-W72 https://bhpho.to/3dkmxnt

Q: 2. Will this hood cause vignetting if used with a 20mm lens on a full frame camera?

A: As the Heliopan 72mm Screw-in Rubber Lens Hood is a universal lens hood, Heliopan does not list a specific focal length or lens for which this lens hood is designed for usage. However, when using a wide angle lens, do note that by rolling back the lens hood, its opening can be made to correspond with a wide-angle lens's angle of view so that vignetting is reduced or eliminated. However, I recommend testing on your own 20mm lens to see if it vignettes, and note that this item may be returned within 30 days of purchase date for a refund or exchange if it does not work for your usage needs.

Q: 3. Will this hood work with a 28mm lens on a full-frame Nikon dlsr without vignetting?

Q: 7. Will this hood fit my Sigma 17-70mm f/2.8-4 DC Macro HSM Lens f/Sony??

A: No, you will still need to use a wide angle hood, because at 17mm it still a wide angle lens. If you use a telephoto hood everything but the 70mm focal length will vignette.

Q: 8. Is the front diameter of the lens hood is the same as it is in the back? Can a 72mm lens cap clip to the front of the hood?

A: Yes a 72mm lens cap can fit this hood.

Q: 9. How does this affect the use of lens caps, filters, or bayonet-type lens hoods?

A: It really only affects bayonet type hoods. The bumper has filter threads on both sides, so it can mount to the lens directly like a filter, or directly to a filter, and also have filters mounted atop it. For rotating filters such as circular polarizers it is recommended to put them atop the bumper.

Q: 10. Does this fit the Nikon 28/1.4D?

A: No, you need the 77mm one. https://www.bhphotovideo.com/c/product/1079788-REG/sensei_lhm_w77_pro_77mm_wide_angle.html
