I just joined this forum and just joined the digital world. Finally I'm giving up film. I have been using a Canon EOS since the 650 and most recently was using an EOS Elan 7e.
I got a brand new Canon 40D camera body for Christmas, attached my Tamron Aspherical XR 28-200 mm lens, and started shooting great photos of my kids. Then, I started to get a periodic "Error 01" code which states: "Communication between the camera and lens is faulty. Clean the lens contacts."
Well, the code is becoming more and more recurrent and the lens contacts are very clean. The camera actually shoots the picture but instead of displaying it on the LCD screen, it provides the error message and I have to turn the camera on and off to get rid of the message, only to have it return with successive shots.
My wife is convinced it is a lens problem. She normally pays little attention to my electronic misadventures (computer troubles, etc.) but she may be right about this one. I would love to get a new lens to go with my new camera anyway. She reminded me that while I was waiting for my 40D to come in, the shutter of my EOS Elan 7e (with the same Tamron lens attached) started sticking. The viewfinder would just go black when I took a shot and I would have to turn the camera on and off. I thought the shutter was wearing out since that camera is a few years old. But, when I got my film developed, not a single photo was ruined, so it wasn't the shutter sticking. Does this sound like a lens problem? I would love some thoughts.
