1DX error code 20....

[inkjunkie]

FIrst let me say I am glad I decided to join the CPS program. I recently purchased a used 1D-X body. Had approximatley 55k shutter actuations when I got it. Used the camera for a few months, shutter count was around 65K when I starterd getting Error Code 20 messages. Sent the body in, just got anemail saying that the shutter charge lever assembly needed to be replaced. Was it just my luck that this happened at such a low shutter count?

"... I could use my Canon 2x Extender with the Sigma lens."

Why not use the Sigma tel-con with the Sigma lens.  Certainly a person that buys a $3500 lens can buy the correct extender?

I have one for my 120-300mm and it works. I don't like it but it works.  I don't like tel-cons in general, however. I have not tried it with my Canon tel-con.
