Hi,

I am just writing this to inform members of a potential problem.

Has anyone here forum had a fault with the Canon 24-105 lens?

The lens appears to function properly at focal distances <50mm. Any greater and "ERR 01" appears.

Reports of repair are in the region £200.

People reporting the problem to Canon are being told it is not an known issue and they have never heard of this before.
However, I have found several dozen reports online within an hour!

Customers who have had lenses fixed report that the aperature assembly was replaced.
One report I saw detailed the Flexi PCB, within the assembly, are cracking and causing the fault.

I am relatively new here and not sure if I can post links, however this person is gathering information (serial #, age, purchase location and canon ticket/case number) in order to provide proof to Canon there is a genuine fault.

There is also a new discussion on the Canon facebook page, to try and make Canon sit up and listen

Good luck if you are one of the owners with the problem.
 
What exactly is the problem with canon's response?
Have they said they can't fix it? If the aperture assembly has to be replaced, I'm not surprised reports of repair are about £200.
From what you say, it's not like they are refusing to attempt to repair it.

A few dozen reports online isn't a massive number for a lens so popular. If that's as many as you can find, it sounds like quite a rare issue to me.

Never had fault with mine and I've had it 4 1/2 years.
 
Don't shoot the messenger. Read my first line again.

The whole point of forums is to share info.

Also I stopped looking after I found a couple of dozen reports. Can't imagine I found every one that has been reported on countless forums.
 
I can't really be bothered looking at the links so maybe I'm not getting the full picture, are Canon refusing to repair lenses that develop this fault whilst under warranty?
 
sorry, didn't mean to come across so harsh.
It does seem like a bit poor service from canon that they are yet recognising it as a known fault, since there are multiple cases.
But still, it doesn't seem very common, and they can repair it, so I'm not exactly sure what the problem is.

A potential design fault causing you to have to spend 1/3rd of the price of the lens getting it repaired.
 
I've had mine for nigh on a year and it's fine and I've not heard of anyone having this problem.
This lens has been on the market for several years, I'm wondering if it's an issue that Canon ressolved in later production runs?

No, nothing like that - I don't see anyone that has even had a failure during warranty period. Seems to be lenses that are 3-4 years old or more. I don't know about a couple of dozen, I don't see that many posts there - most posts are "mine works fine", others saying they've had Err01 with the tamron 17-50. Another poster had an issue that was different as the repair bill was much lower.

So it would seem if a 24-105 does fail it fails with common symptoms.
 
Ok, no offence taken.

I'm not sure on the persons end game, however i suspect it is to make Canon at least acknowledge the fault. Maybe Canon can identify a pattern, identify different materials used, different parts used???? And then possible issue a recall????

If it doesnt get reported though.........

I have been looking at buying a 24-105, I only found that forum because I was reading about them.
The L lenses are supposed to be the cream, if i was an owner I wouldnt be happy with them breaking down after a year or two and having a £200 bill, regardless of how rare an incident, when Canon knew about it.

I understand there are going to be thousands of people without a problem. However, im sure the ones with a problem wouldn't mind taking a few minutes to read the links.

Again, I was only posting this for information. Just trying to be helpful.
 
fwauba wouldn't let that put you off buying one, the 24-105L is a subperb lens.
As Craft has pointed out, that link seems to indicate the fault is more common with lenses 3-4 years old.
There are many people here who use one and I think we'd soon know about a lot failures from members.
 
It could come under SOGA so the retailer might have to stump up some or all of the repair costs. A £600 lens should remain fully functional for quite a while. It just depends on how long and how much use you've had before it develops the fault.

How many of the ones online are the same person complaining on different forums? Also there are a few that moan about faulty lens then later on you find out it's been dropped, banged or gone for a swim.
 
Hi,
Thanks, Hashcake, It's not put me off getting the lens. I still really want one. Just if I am unlucky enough to get a fault, I would like to know Canon would be good enough to give, at least reduced, repair costs, as srichards said. If indeed it was due to faulty parts or design flaw.



Anyway, does anyone have a 24-105 for sale. Obviously I want it cheap 'cos of the horrendous reputation it gets for substandard parts.

Joking :-)

I'm not really seeing the problem then.
The PCBs have failed on a few lenses outwith the warranty period, why would Canon offer reduced price repairs?

For all we know those lenses might have had pro use, it might only be lenses that have been zoomed in and out a lot more than average that have developed the fault.

Given the number of 24-105s out there I'd not really expect Canon to bat an eyelid until there's several thousand cases of this or the failures start to develop some sort of consistency ie, all the failures are in lenses manufactured in 2005 etc.
 
Hi,

I'm sure you would have a different opinion if you happened to get a dodgy lens.

One of the link I posted is someone gathering exactly that kind of information.

I have owned at least a couple of bits of electronic kit that have failed just outwith the warranty period. It's annoying but it happens.

I'm currently without a laptop because the graphics card just failed again 3 days after the warranty on the repair I had done to it in November expired. When I went into the repair place with it in November as soon as I pulled it out my bag the member of staff behind the counter asked, "Screen gone fuzzy?" He said that it was a common problem with laptops that used the graphics card that mine did.

Unfortunately most of what we buy these days has a bit of designed in/built in obsolescence. You can spend a fortune on extended warranties, shun modern technology and use old mechanical equipment or you can accept that failures happen and not get your panties in a bunch when they do.
 
OK,

Everyone has their opinion.
All I done was pass on information on a "possible" fault, in which I think I was right to do.

If the Mods think it useless, feel free to delete the thread.
