Lens Problems

Day after Trevor's 5oth, I didn't drink but I'm still tired.

The plasters came round, the conservatory has a sort of ceiling now.

I'm having lens problems. I bought a 24 - 105 mm canon lens second hand a few weeks ago, how it has a fault. Can only shoot wide or get ERROR 1 coming up! Apparently this happens a lot with these lenses!! Arghh!!!
