I find it highly suspicious.
Strange that we suddenly have quite a few first time posters asking the documents to be published or claiming that they've had problems with their gear.
I do not find an issue with that.
Maybe it is, may be it is not.
I am not a first time poster and at the same time asked for more material. The reason is I have a 24-70 2.8 ii which did not belong to any of the problem' categories were referred in this forum (clicking, bubbles, front element coming in contact with the filter and coating issue). So I though I was lucky.
But i stumbled upon 3 Errors 01 (Communication between lens and camera). Since the lens was new and the camera didn't have issues with any other lens it was a 24-70 2.8 II lens problem. It didn't happen again but I will always be afraid that it might happen so in important shootings I will have to carry a backup lens of similar characteristics. Now I learn that my lens will possibly have issues with a problematic spring (if seems it is made before aug 2013).
So yes I do want to know about Canon issues.
