Hello,

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.

Thanks.

Hy5

Take a qtip and dab some rubbing alcohol on the qtip. After, gently rub the alcohol on the lens contacts (on just the lens side...40D should be nice and clean). After, just wait for it to dry, or carefully wipe it off.

It should work.

Your wife may be right. If the lens shows problems on 2 bodies then it may have a fault.

No other lens to try?

Thanks. I will try that.

I do have another lens, but it is a fixed focus lens. I seem to have problems when zooming which makes me wonder about the lens itself. I will try my fixed focus lens.
Thanks.

Fixed Focus Lens?
You mean it's focusing mech is broken? or what?

Some older third party lens have trouble on newer DSLR's. Something with the computer chip.

I think you mean "fixed focal length"... In other words, a prime lens like a 50mm, etc.

Depending upon what it is, it might be fine. Especially if it is a Canon EF lens, it will give a better test of the 40D.

Please do not, I repeat, do not get Q-tips anywhere near the rear of the lens or anywhere inside the mirror box of the camera. Cotton swabs shed fine, tough threads that can jam a shutter or otherwise make a real mess of your nice new camera. It's usually an expensive repair ($250-300 for a shutter replacement, for example). Why take a chance?

Use a small pair of tweezers and lint free paper towel or tissue (Kleenex). Just tear off a small piece and put a few drops of isopropyl/rubbing alcohol on it, then wipe the contacts as suggested. (Note: I also don't recommend using a pencil eraser, which some folks might suggest. Erasers also can easily leave small particles in there where they can cause problems.)

Clean the contacts in the camera, as well. Not just on the back of the lens. It's possible there are some residual oils on them from manufacturing, or even a slight haze of oxidization on the camera's contacts in the camera, from storage and shipping, just the same as on the back of the lens.

However, I suspect your problem is more likely a matter of mixing an old lens that has some problem, with a new camera that's fine. Best bet would be to try a different lens and see if it solves the problems (on both cameras, for that matter).

Thanks. I will definitely avoid the Q-tips and will see if I have a defective zoom lens.

I had the same intermittent Err 01 on my 1st copy of 17-55, turned out to be the error was from the 17-55 as other lenses that I've got never gave me the this type of error. I exchanged the lens and my 3rd copy is definitely a keeper.

I have the same problem with my 3rd party lens. The two Canon lenses I have from my film days work fine, but my zoom gets the error code off and on. Could it be a voltage problem with an orler lens?

Just trying to get better!
