Stroke of Luck with Canon 70-300 IS USM

[RichB]

A year or so ago my rather favoured 70-300 IS USM F4/5.6 took a visit into a stream while I was getting out of the way of a rally car, being sensible I put it in the boiler cupboard for 2 months before trying it and was saddened to discover that it showed no sign of life.

Well I picked it up the other day to use in it's manual form after ignoring it for a year and I was using it again today when I had the decidedly less sensible idea, based on the fact that I couldn't feel any gear slack in the focus ring when it was set to AF, that I would just wrench the focus ring with it set on AF and see what happens. Well when I got to 'stuck shut jar' torque I didn't do the sensible thing and stop but continued until there was a loud snap.

So naturally I admonished myself for my stupidity expecting the lens to have suffered an egregious injury but to my surprise it had returned to full functionality.

It's probably not worth a thread but I'm in quite a celebratory mood about it.

Congrats Richard,

It must have been jarred by the fall as much as the water ingress.

Cheers,

Yeah I've been wondering what did it, I wouldn't have thought that landing from half a meter into water would be that bad. I wondered if the heat from the boiler caused it. Either way I'm a happy bunny and will go and find a UV filter for it again.
