When we were at our last AP meetup my camera showed this error 01 all the time and I had a lot of trouble with my camera all day.

This error suggested the pins needed cleaning between the lens and the camera body.

It only seemed to be with the 24-105mm on my body.....Canon 40D

I tried the lens on Andrews body and it seemed fine.

I tried other lenses on my body and it seemed fine.

As soon as I popped the 105 on my body it would shoot off a few and stop with the error again.

We cleaned the terminal pins over and over.

We took "all" the batteries out along with the memory card.

Does this mean my wonderful lens is #@%$&...???

When it works, sometimes you can see the lens flicker inside the viewfinder and sometimes seem to slow a tad.

Please tell me this is fixable!
