Anyone else getting this problem ?
I've already lost one hood and the second hood only lasted about 6 weeks before started to drop off as well.
The latch seems secure and it clicks in nicely when you put it on, but whilst out on a walk with the camera on a shoulder strap it will fall off 3 or 4 times, and when wondering across moors / soft ground you don't hear it drop off so am just debating glueing it on !

presume its not a fault with the hood itself, as the second one exhibiting same issue.
the lens thread seems clean and I have used air and brushes to see if there is a small amount of dust / dirt in the screw that stops it from connecting securely (but like i say, the hood clicks into place)

any suggestions ?
