Re: Canon 24-70mm f2.8 ii flex cable ribbon problem again

I have two 24-70 f2.8s and they've both had this error and apparently the same problem. One I bought used from a photographer and it broke about a week later, and the other I got from a coworker at the paper who'd bought it new and it lasted about a year until it broke just last week.

Re: Canon 24-70mm f2.8 ii flex cable ribbon problem again

Aloha Canon Community, 

 

I'm very dissapointed to find this thread after a quick google search on why my 24-70 f2.8 will only shoot wide open. This very same issue happend to me yesterday. One of the busiest times of the year for me, shooting large families at 2.8 is definitely frustrating. What's more frustrating is reading the comments in this thread. It is obvisouly a manufacturing issue and from what I'm reading, Canon is not doing anything about it.

 

A bit about me,

 

I am a full time professional shooter, video and stills. Located in Hawaii. I purchased this lens 2 years ago. I was talking with another photographer friend of mine on island and they have also experienced this issue, same lens, same problem. 

 

To the OP,

 

Have you had any updates from Canon?

Sorry to hear that, but you're in the wrong forum, nobody will help you here, they all say that the problem does not exist. Read the whole thread and you'll find my posts. I already gave up on the 2 24-70 (yes! Two!) I have with the same problem

Of course, no one can help repair the lens.  This is not Canon Support.  You would need to contact them directly, not here.  That is the best "repair" adice you will get here.  

 

I apologize if that sounds harsh, that was not my intent.  But if you read the thread then you would see that advice is given.  I understand that people get frustrated, and some wish to vent steam, too.  But, this is not the Canon Repair Center.  This is a user forum, filled with camera geeks who think they know what they're talking about.

Re: Canon 24-70mm f2.8 ii flex cable ribbon problem again

I am the original poster of this issue. 

It has pretty much been discussed to death with heated discussions on both sides. I have multiple 24-70 lenses and they have all had the problem multiple times. It is frustrating. 

Canon has offered no compensation for the problem. I have stopped using them for the repairs on this issue to save money. Before people sound off on that... it has nothing to do with the service of the lens or who is repairing it. 

I say a design flaw and or weakness as its very susceptible to this problem. I have dealt with it at least half dozen times on different lenses. 

Good luck! At least you know what the problem is and there is a work around to keep working. 

ps: People... let's stay positive and supportive to one another. We are all here for information, help and advice. :-)

Re: Canon 24-70mm f2.8 ii flex cable ribbon problem again

Just to keep the community informed.... Just had the lens again fail today with Err 01 Code. It will shoot on F2.8, but if you change the aperture to anything else than wide open, it fails. 

I've lost count on the number of times I've repaired this lens model. I have multiple lenses. 

Kinda speechless at this point on the how and why it keeps happening. 

I do wish a customer service representative from Canon would extend the courtesy of saying, let us look into it for you and credit me on the repair. But hey... that's just wishful thinking this holiday season! 

Merry Christmas Kidos!


ps: Here's a video on this lens with the problem:

Canon EF lens ERR01 with error message of lens contact problem. This usually have to do with aperture module control error. Aperture cannot shut to smaller value either because of the ribbon snap or the aperture control motor faulty. The best bet is to change the whole module. Here is the step by step guide to change it

Re: Canon 24-70mm f2.8 ii flex cable ribbon problem again

The same thing happened to me.  I googled and came across this forum discussing the problem.  24-70 ii, can only shoot wide open and nothing else.  Tried different lenses so know it's not the body.  Tried usual cleaning of contacts several times, does not fix, consistently ER01.

 

Just wanted to add a data point.  This is my main lens so it has been fair bit of use and have owned it for several years already. Suddenly just decided to fail on us. Maybe didn't notice recently as usually shoot wide open.

 

Hoping for simple/self fix as i'm quite handy. But looks like I have to cough up for the service center fix.

It cost me 150 euros. Canon official repair service in Athens.
They said, that they replaced cable and reinforced it. Looks like, Canon service is aware of the issue. I wonder if newer models, have this issue fixed.

I guess will have to start saving up for it! I noticed when i turn the zoom ring, i can hear a soft click like a ribbon being rubbed against and when reversing the zoom, can feel/hear the same 'click'.  Sounds like I have the exact issue which many people have.

 

edit: just got a quote for $380+tax... yikes...

Update... I received back both of my 24-70 USM II lenes a couple weeks ago. One lens needed a new aperture so not the dreaded common ribbon cable fix that made me start this thread. The other lens tho... BLAHHHHH.... flex ribbon cable again!

I've lost count on this repair. I don't think it's double digits yet, but getting close.

 

It's almost time to move onto the new Canon R6 and get me a RF 28-70 F2L USM lens... but at $3K each for that lens... it will be a while before I replace my stable of 24-70 F2.8 USM II Lenes. Let's hope they figured out how to make them last!

 

I love Canon... but things change, and my old love isn't the same as it used to be!

It's a big decision to leave Canon and start over with another brand with it's own challenges. That being said, if there is a right time, it's now as I start to move to the mirrorless world! 

My feelings about Canon these days are they are always late to the dance and playing catch-up! Don't get me wrong... I love them and wish they were more on the ball with my personal needs. I have spent countless on them for years and have camera bags full of gear. 

Do me a favor Canon and knock my socks off with your next release that will renew my faith and make this decision easy for me!
