I ahve had this since new.. just noticed when cleaning this.... its on the inside..

Been out in rain a few times but not much more than drizzle.. obviously a pic makes it more prominant.. you ahve to actyually angle the lens to see it in real life and as i usually either use it in dark places or its on off busy then i hadnt noticed it before :(

cant remeber when i bought it but out of warranty..

what next ?: (

What a coincidence...I was cleaning mine last week and noticed something inside. Nothing visible in pictures but irritating all the same. Take it in to CPS for maintenance clean?

Are you sure it's on the inside? A little while ago I had a massive problem with the coatings on the front elements of these lenses (and only these lenses):

hmmm.. nothing changes using anything on the outside so i preume inside.. hard for me to say for sure :(

looked at your thread.. can see final outcome that canon will replace any more you get.. but do you have any cost ideas for one ?
 
ps all the pics i ahve seen of fungus looks like growth and has a simmilar pattern..... nothing like mine

pps its around 75% of the edge of the glass.. round not inwards ..
 
Unless you've had more than one of these lenses then it's the one that you bought from me about 2-1/2 years ago, Tony.
I bought it new in 2014 (2013 date code) and used it once for a wedding before seliing it to you in early 2015.

If you can wait until Monday, I'll dig out the maintenance records and see what I paid for them.

Well, I had to get something from the office so I dug out the maintenance records.

We had 14 front elements of this type of lens replaced in 2015-2016. Prices including VAT were
£153.05
£128.20
£156.50
£156.50
and then Canon paid for the other 10.
 
My 70-300L went like that, no other canon lens i have,has done it, i complained , asked for manager at cps etc, they agreed to knock 30% off i think, still cost me £183 , its a faulty coating, but they weren't bothered.

On a similar note, my MacBook pro retina screen went like that before I got it replaced under warranty, its definitely the coating thats coming off. It won't look or feel like its on the front element and not inside but it will be, have you used anything to clean the lens thats perhaps damaged it, thats what happened on my mac, that and rubbing a bit too hard.
 
If that's moisture and the lens is supposedly waterproof then it maybe a trades descriptions act issue.

I'd expect Canon UK to service that free of charge.
 
I cant tell.. my missus says it looks on the outside and maybe coating.... Roll on the 9th october when i get it into canon..

Lenses (and cameras generally) aren’t waterproof... they are weather resistant. A term which means nothing (legally) and doesn’t indicate that a lens can be used in particular conditions.
 
If that's the case it's pointless buying "weatherproof" lenses isn't it?

And it DOES indicate they can be used in inclement conditions. That's the whole point of being weatherproof.

They are more weatherproof than other lenses; however they do not offer any guarantee of the amount of water they can cope with!
 
Please desist using exclamation marks where they are not necessary. You came across as rather exasperated in your reply to which was a valid statement.

If a manufacturer has stated "weatherproof" on an item this must be measurable, otherwise there is no point in stating this in the first place.

A manufacturer states weatherproof when they have built an item to a standard to be proofed against some “weather”. But weather is an undefined term... a light summer drizzle will be okay; using it in a monsoon is unlikely to be: but ther term is undefined.

Waterproof on the other hand has international standards to back it up.
 
Some of Canon's weather resistant lens are only so when a front filter is fitted, my 70-200 f4 is L is one such lens, don't know about the 24-70 2.8 MK2. If this is the case with this lens then perhaps Canon could claiming hadn't been used in a manner to create a waterproof lens and so invalidated any warranty?

FWIW for this lens:
Specifications state "Dust/moisture resistance".
Instruction book states "Tight seal structure ensures excellent dustproof and drip-proof performance."
 
So if that's moisture in the lens the OP has a case for Canon to answer. As I suggested in the first instance. Thank you Tony

No, because water damage is specifically excluded from Canon’s European warranty.

Says that about my 70-200 but it also says I need a filter over the front element to maintain the seal.
 
The 24-70 is an extending lens so it will always draw air in as the internal volume increases.

Except the damage appears to be nothing to do with weather resistance, it definitely looks like damage to the lens coating.

Whether that damage is due to the coating being crap or user error is an argument between the owner and Canon.

@KIPAX - If it comes to this, I'd be happy for you to quote my experience at them. My problematic lenses were mostly with 2012 to 2013 date codes, so yours could be from the same batch. There are some quite extensive details in post #48 of that other thread, but if you want me to dig out chapter and verse, dates, serial numbers etc then just drop me a line and I can do so.

Incidentally I think the reason we had these problems might have been down to the fact that we clean our lenses so often. They get a lot of use - especially workhorses like the 24-70mm f/2.8 - and obviously we make sure they're clean before every hire. So they get more exposure to cleaning tissues, solvents etc and if there's something about the coating that means it's less durable, it could be that we're just finding it sooner because we do more cleaning. That might be an argument you could use with Canon too.
 
Ah I see sir, you have been using these lenses, to take photographs? Mmm I think this might be where the problem lies .......:)

Same with us. Any kind of solvent is always the last resort, like the time when a client hired a lens for "glamour/boudoir" work (probably porn in other words) and it came back with blobs of wax on the front element. But anyway I reckon if the coating isn't properly bonded to the glass, it might be that we're effectively rubbing it off with tissues, even without solvents.
 
So canon have the lens..

they just phoned me with a fixed cost repair of 156 pounds which i agreed to..

then i asked.. was it the coating on the lens.... she replied... do you use a lens hood.. the technician says its probably the cause..using a lens hood

WHAT!!! ? :(

So i asked them to look at the repair sheet i sent in showing exactly what the problem was with the lens...

oh right so its just the glass you want replacing?..

.duh :(

am awaiting another phone call when they are done.. i will ask if glass replaced and still same set price


Not amused :(
 
So posted the lens monday and I wlil get back tomorrow Thursday.. total cost £156.50 and from I can gather it is the film? at the front..

I wont know exact details until I get the work sheet they send back qwith it... also had my 1dxII cleaned and serviced.. so all done and back 4 days monday to thursday :)

All in all not a bad experience apart from the mix up of what was wrong with it..

I really don't think you should be mentioning blobs of wax, glamour/boudoir, porn and rubbing off with tissues in the same sentence.

My tea missed the computer keyboard thankfully.
