I am having some issues with this lens and I am wondering if anyone else has it or is having troubles.

Lately, after almost every shot, I am getting an err o1 communication between lens and camera is faulty. Clean contacts.

I have done EVERYTHING possible and this pops up after every single solitary picture. (I release the lens and unhook the battery and restart) My thought is that it is the lens as I can put the lens on and turn it to the point JUST before it locks and use it normally (All though no AUtofocusing or F-stop) but as soon as it locks and I take a photo I get the error.

I don't have another lens so I can't really test to see if it's the lens, but the camera works normally Sans lens and Sans locking the lens, as soon as the lens locks on it errors out.

I am going to send the lens in for repair or replacement. At first I thought it was too hot.. but even after a cool down period and a good cleaning with alcohol it still continued.

I do have to say that without it locked on. I got some amazing and perfectly lit and balanced photos.

Anyone else experience this?

Are you still using a Canon XTi?

No.. No it's my 50D. I bought both (Separate) in February. Boy, you are either observant or I have it the Rebel listed somewhere.

The XTi is listed in your profile. It's nice to either list current cameras there or mention it in the thread, but it doesn't matter in this case. (Some of the 1D series cameras have a lens-mount switch on the body which could simulate your current issues, but you don't have a 1D body, so ...)

What happens if you fully latch the lens and press the DOF Preview button (instead of the shutter button)?

What happens if you set the aperture wide open and try to take a picture?

I totally forgot.

Same- Err 01

Same err 01 t F4.3 and at F22

When you press the DOF Preview button, the body attempts to communicate with the lens, telling the lens to "stop down the aperture".

When you set the aperture wide open on the camera, the camera no longer has to send that information to the lens, so it simplifies the communication to just coordinating AF information.

Since the camera is unable to communicate in either situation, it sounds like all communication to the lens is severed. There is still a possibility that the camera could be the problem, but I agree that most likely the lens has failed.
