There is no surprise, of course: this lens hood is designed for the Tamron 10-24 and therefore perfectly adapted to it. Once in place, it gives a pretty impressive aspect to the goal you switch to a pro in the middle of the tourists. It can remain permanently on the lens by turning it upside down, but be aware that it adds a big thickness to the whole. In my Lowepro bag, including more accommodation for my goals, I can not fit all in one place (or so I should expand it at the expense of others)
