Love the build quality of the lens...bleh bleh.....


I was able to take maybe 2 shots before my camera's flash (REbel T2i) started going crazy...like in a way that would make any subject go into shock or epilepsy! At the same time the lens was unable to focus on any subjects, again continuing to cause the flash to go NUTS!


I have tried searching on google for this, but can't find an answer?

Could the lens be broken, or could it be something wrong with my camera? Battery levels seemed ok etc, so really confused right now.....and a little dissapointed after dropping a lot of quid on this lens (for my first foray into 'proper' digital photogrpahy).


All help appreciated!
