The 58mm Heliopan Screw-in Rubber Lens Hoodis designed to prevent unwanted stray light from entering a lens by extending and shading its front end. This prevents lens flare and improves image contrast. In addition, since the end of a lens is extended when using a hood, you also get the benefit of extra protection from accidental impact to that lens's front element.

This lens hood is constructed with a rubber compound that is UV and temperature resistant, and the rubber material can be rolled back for storage or to convert the hood for use with wide-angle lenses. 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 avoided.

A metal mounting ring connects the hood to a lens with 58mm filter threads and a 0.75mm thread pitch. The mounting ring also features corresponding 58mm front filter threads which can be used to accommodate filters, lens caps, or other threaded accessories.

Q: 1. what focal length is this hood for?

A: I use this on several lenses. I can push it back to make it smaller, it is great for packing and taking on trips, it has never interfered with any photo when in full out mode or pushed back. Its is great, but I would buy two, once you begin using this, you will love it so much if you loose it or misplace it, it will drive you nuts. Hard hoods will be a thing of the past.

Q: 2. If this lens hood is used in Sony FE 16-35 mm F4.0 ZA, will it cause vignetting?

A: Yes on 16 mm.

Q: 3. Will this hood work on a Sigma 150-600 lens? It is on a Nikon D7500 camera if that matters.

A: Yes, the Heliopan 95mm Screw-in Rubber Lens Hood is compatible with the Sigma 150-600mm lens.

Q: 6. Are there pics or a video of how this attaches to lenses?

Q: 7. Does this hood “extend” or is it only 0.8” deep? Want to use on a Tamron 150-600 for easier traveling than the one provided.

A: This hood is nominally 1 1/2" in depth. The only 0.8" listing we have attached to this hood is the depth of the box it comes in.

Q: 8. Could this be used on a Nikon 62mm polarizing filter to allow easily turning the polarizer?

A: Absolutely.

Q: 9. 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: 10. How deep is this hood?

A: About 5 inches and it is well versed in the works of Kant and Aristotle.
