The black, mini OP/TECH USA Hood Hat is designed to fit a lens and shade with a diameter from approximately (6.4 to 7.6 cm). Simply placing the Hood Hat onto the front of the hood while in place will provide just as much protection for the critical front lens elements as would be provided by a traditional lens cap. The neoprene material will adjust to fit both round and elliptical "petal-type" shades.

Lens hoods with significantly larger opening than the lens diameter may require larger model hood hat. This item is made in the USA.

Related Questions and Answers

Q: 1. Will it fit Canon EF 85mm f/1.2L II USM?

A: It will fit the lens. The diameter of the 85 f/1.2L II is about 2.8 -2.9". It might be a little loose unless you push the hood further in.

Q: 2. Will the XL version of these work well with a Nikon 70-200 2.8 and 24-70 2.8? The large fits but requires 2 hands to take on and off as it is pretty snug.

A: No, I'm afraid the XL will be too big and fall off as you're moving. I use the XL on y Sigma 105 f/1.4 hood and its a lot bigger than the 70-200 hood. I use the L over the hood of the 70-200, 24-70, & 17-35 without issue. If you want one for use without the hood, the M seems to fit. Be aware that after walking in the hot sun, they do stretch quite a bit and become a lot looser.

Q: 3. what is the actual length ?

A: The depth/length of that hood hat is 2 inches.

Q: 4. The Canon shade on a 300 f2.8 measures 5 3/8. Will this stretch enough?

A: Yes this will be able to stretch over the lens hood of your Canon 300 f2.8 measuring 5 3/8".

Q: 5. Will this fit the Canon 500mm f/4 IS II?

A: Hi, I use the XXXL on my hood on the 400 2.8. It is a bit tight but stretches lots and stays on well. Also rolls up small and fits in my back pocket when I forget to leave it in my lens case. Doubles as a nice tray to hold stuff, lens caps, card holders, small lens hoods, etc on my desk when I am editing and filing on location. Hope this helps. James Carey Lauder, Winnipeg, Canada

Q: 6. is this the right size for a Leica Q? or the mini?

A: I use this item on my Leica Summilux-M 1.4 as I was always loosing the Leica Cap...not to say I haven't lost a Hood Hat, but they stay with me longer. I just tried it on my friends Q and it fits. A little tight...requires both hands...but the next size up may be to big. Make lots of images. Best C

Q: 7. Will this fit a canon 400 2.8 ET-155?

A: No, the OP/TECH USA Hood Hat, XXX-Large is too small for the canon 400 2.8 ET-155. The LensCoat Hoodie Lens Hood Cover (4X-Large, Black)should fit, https://bhpho.to/3IWUevu .

Q: 8. What is the purpose of the tab on the side?

A: The tab on the side is to help pull the Hood Hat down more easily.

Q: 9. Would this fit over a Sigma 24-70mm f/2.8 DG DN Art Lens, or should I use a medium?

A: The OP/TECH USA Hood Hat, Medium will fit on the Sigma 24-70mm f/2.8 DG DN Art Lens for Sony E.

Q: 10. Thank you to the folk who answered my initial question! I guess the clarification I'm looking for is regarding the measurement stated in the item description. The measurement given is for the lens it seems, not the hood. So, for example, would the micro hood (for a LENS between 2.0 to 2.5 inches) be the right size if that lens has a 2.75 inch hood? Thank you!

A: Yes it will fit a 2.75 diameter lens because material is elastic like that of Urethane foam wet suit for divers. I suspect that if you left hood on 2.75 lens for long-term storage, hood may no longer fit as snugly on 2.5 diameter lens. Just a theory. I use hood on Sony 10-18mm ultra wide lens which has 2.75 Diameter. Hood is well made. Good insurance. Shelly on Oct 31, 2015
