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.

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
