Hi im using a recently bot 2nd 40D with 17-85. My bro fell down with the cam (lens receiving the impact, filter scratched), it showed no problems at 1st. After his photoshoot, it takes the camera eons to focus (keeps going to and fro 2 distances). Even if there's finally an AF lock, AF is super inaccurate (10m when object is only 3m away). The cam also sometimes displays something "Err 1: lens not connected properly or contact needs cleaning." cleaning and re attaching lens doesnt seem to help.
Can someone pls help diagnose the problem? I suspect the AF motor/beam/receiver is damaged, mayb due to USM ring movement during impact. I dont want to go down to CSC and get charge for changing some part that wasnt spoiled. thanks in advance
