I have a couple of these lenses and I do really love them. They are the work horse in my stable of glass.
That being said, this is the 3rd lens now that has failed with the ERR code communication problem. I have had this happen a couple times before so was able to trouble shoot the issue and know that its the flex cable ribbon that is bad inside the lens.
It will work perfectly as long as you shoot at 2.8 (the wide open aperture setting). As soon as you change it and the lens needs to change the aperture for a image, it fails.
Now, this is the 3rd time with 2 different lenses that I've had to send them in for this repair. It would seem to me that this is a defect in the lens and I should not hae to pay for it. Or... Canon needs to use better parts so this does not keep happing over and over again.
Yes I use the lenses a lot. And yes, they are out of the warranty period. That being said, they should step up and repair without quesion. The have to know that this is an issue with the lens.
Anybody else experiencing the same issue with their Canon 24-70mm f2.8 ii?

"Why is eBay and Amazon have a plethora of Canon flex cable ribbons for sale"
Hardly proof of anything except Canon parts for sale.

I get that feeling to especially with this particular thread I started a while back.
I was trying to post my problem and get some help with it. I was made to feel like it was something I was doing, and I started to defend myself.
Just sticking to the facts and not trying to make up any interesting details. I take care of my equipment, who doesn't, when it costs this much. I also use it a lot!
If there is something I shouldn't be doing with this lens... let me know. Sometimes I pan and shoot... zoom and shoot ... looking for light bleed and action. Is this lens susceptible to failure when it's being zoomed and the aperture is changing?
I've never dropped the lens. Or I should say lenses. Not that my assistant would tell me. haha
Anyway. Stay positive people. The problem is real for some of us. And paying $200 to $300 per repair isn't fun. I've started using my local shop to fix my gear. Paying $50 and it's done! Works a lot better for me.
Im not going to get into the quality control of Canon I've had over the years. I have sent gear in only to get it back with a new problem or not fixed. Im sure they are doing their best. Don't just jump on the band wagon shouting Canon Canon Canon for everything. I don't see any Canon Customer Service reps reaching out to me to talk about it. Well, maybe some of you do work for Canon. I don't know.
BTW: When the problem does happen and I get the ERR01 code. Sometimes its obvious and will happen every time I take a picture with an aperture other than 2.8. Sometimes when the problem is intermittent... I can replicate it by zooming and taking a picture at the same time. Guessing that the flex cable connection is loose. Or the movement of the lens is causing it to disconnect.

Yes, it seems that in this forum instead of helping Canon users with problems, the "top contributors" try to deny the fact of the problems we have. What do they think? That we are making up the problems?????
Of course not. But if something is happening to you every few months that's unlikely to happen even every few years, then common sense requires that you look carefully at what you may inadvertently be doing to cause it. Even if it turns out not to be your fault, identifying possible causes may help Canon find and fix the problem. I think it's fair to say that Canon does listen to what professional photographers tell them.

Yes... the problem is coming up around every 6 months give or take.
"Common Sense"... funny expression.
I have looked at everything I do and talked about it here in this thread. Again, I usually get a lot of resistance from the contributors. Kinda like what you wrote and was followed up by ebiggs1. Putting the blame on me. I do not want to argue and start getting off topic so don't take that the wrong way. Im looking for a solution to the problem and listing the facts and what I do and use the lens for. Maybe it IS my fault. If it is... what could a person do to make a ribbon cable fail over and over? I have talked about my use of the lens. So just play devils advocate for a minute and make up a scenario where you could "abuse" the lens to make that happen? Other than just dropping it and causing damage. Because that is not happening. I do use a Rapid Strap which wraps around my shoulder and the camera sits on my hip. I guess you could say the constant bumping against me when I walk is causing the damage? Is that possible? Sure. Likeliness... I dunno?
Let's talk about "common sense" again. Another way to look at it, common sense would say there is a design flaw with the lens? Or at least a weakness in its construction. Now why isn't this happening to everyone? Again, I do not know. But I do know I’m not the only one having this problem.
Stay positive people... this is a forum by us for us right!

"Stay positive people... this is a forum by us for us right!"
All my answers are aimed at help. None are meant to be taken as being rude, The nature of an emotionless forum with simple b&w text may seem so sometimes. Not intentional, I assure you.
"...what could a person do to make a ribbon cable fail over and over?"
Obviously we do not know. My experience is no problems and I have had each and every version of this lens. You are unlikely to work your lenses harder than I do or did. I also use a Black Rapid strap. If it happens to you every 6 months and you are having Canon fix them you should have warranty. Right? Canon wil know why the flex cable is breaking at least after several repairs done on the same lens for several years in a row, they will know. Make sense? You can see where the, "what is common sense" is in this issue?
The 24-70mm f2.8L just might be the best selling and most used Canon lens by pros. I guarantee you if a full time, making money, pro is having to do a repair every six months, they would stop using them. I would have!
Do flex cables break or come off their connections? I don't know first hand, I guess they do, but it has never happened to me on any lens form any manufacturer. And, I have had well over a hundred lenses. I have 20+ as we speak.
Here is what you do. Send it to Canon with a plain, not accusatory letter explaining what is happening, the history, any receipts (no matter from whom) and ask for help. That is about the best Robert or I can offer. Besides that, I wish you the best of luck. Let us know, however, what happens.
