Err 99 and Sigma 50MM Macro

[Ron Wilson]

Just what I need, another problem with my new DRebel XT. I took 10 shots with the Sigma lens before it decided to go Err99 on me. I ruled out everything else. The problem only occurs with the Sigma lens. Card, battery, and all other lens were isolated form the Sigma. I am sure that it is the problem. I will speak with Sigma to see if it can be rectified but I will probably sell the lens to someone who can use it.
Not Happy. Just a warning to others out there. If anyone else has had anything similiar I am listening to any advice.

Take out the camera battery and the button cell, remove the lens, leave it for 30 seconds (being careful to prevent dust getting in), then put it all back. If it doesn't help, call Sigma.
