Can I please get some owners opinions please!
I've owned this lens for a while and coupled it with my 450D and it worked fine and I was pretty happy with it. I upgraded to a 5DII fairly recently and have used the lens a little with it once and never noticed any issues.
I went to the zoo yesterday and today and got the lens out for the first time in a couple of months and noticed it wasn't working very well.
The auto-focus was acting crazy. Sometimes it would lock on focus, but it seemed most of the time it was just hunting really badly. I missed so many photo opportunities!
It would hunt for ages even while I moved the lens around trying to lock onto something- anything! To make it stop hunting I would have to change to manual focus, take some pictures with that, put it back on Auto and MAYBE it would work for a little while after that... If I was lucky. Turning it on and off didn't help either.
I made sure the subject was within the focus distance, it was happening in pretty good light as well as dim light, subjects were contrasty enough that it should be able to lock on. Tried on all different AF modes and still didn't help.
Basically I was getting super frustrated with it and was about ready to throw it against walls. It was pretty embarrassing standing next to other photographers with my lens hunting away, not locking on to anything. I'm sure they noticed because it was loud enough...
So, does anyone have this coupled with a 5DII and is this behaviour normal? I'm pretty confident it's not, given I've owned the lens for so long and not had a problem like this.
Has it just..Broken, for no reason? I'm confused if it has because sometimes it will work fine but it's now completely unreliable
