The lens hood on my 40-150mm fell to pieces on my recent trip to Botswana (yes I made it there and had a truly wonderful time). I've had it for years with no issues and I wonder whether the 40 degree heat had an effect as it appeared that the outer ring was glued. I managed to sellotape it together so it worked for the holiday, but I will struggle to attach it again I think. If I remember rightly, people bought a third party hood. Can anyone point me in the right direction please?
I will post a few photos eventually, but I am still busy culling and organising them. They will not be of the same high standard as

My camera reset itself somehow on the first day too - so no capture time and an old date - quite bizarre.
