I had the same problem on the 24-70ii and some folks have had free repair on a defective lens issue. Never had any problems with other canon lenses, and it's kinda BS that the coatings can go bad so easily, where other lenses dont have the issue.

for reference

canon wanted $600+ for repair, I'm not paying for that, no way. They were willing to give a discount as well, but that's a nonstarter as well, as the front element is $240 on it's own.

Glad the 24-70 2.8L II I just ordered comes with a free B&W filter ;)

yes ive had pictures ruined because of smudges. a whole series on a few occasions. that's one reason I use filters because i'm not gentle when cleaning a filter and I use whatever's handy

over the last three years of fairly heavy use in all conditions I managed to get a couple of light scratches on the front element of my 24-70L II but what really prompted me to send the lens in for service was marks all over the front element I thought could possibly be fungus. it was not fungus but wear through the coating and I mean a lot of it. I do use a UV filter most of the time but for night photography and twilight stuff I use NDs or no filters at all. I've had to clean the front element a few times and sometimes not delicately while in the field so maybe a foreign object got lodged on the rag or my tee shirt or whatever I happened to use.

none of my other lenses are scratched or have coating wear.

anyhow I've decided not to use canon service any longer for non-warranty work because of their poor communication and sometimes steep charges.

the cost to replace the front element and the tattered rubber gasket is $468 shipped. This also includes cleaning and calibrating and a six-month warranty on work.

meanwhile I bought a new 24-70L II for an authorized dealer for $1639. after i sell the repaired lens to my buddy for $1200 (its his birthday) i'll pocket a little change and i'll also have a new lens with a one-year warranty, and also a 13-months no fault repair or replace policy for the merchant.

sure glad it wasn't fungus  :p

I had teh same problem with my 16-35 II L. After 6 years of heavy wedding use...and no hood because lets face it...UWA hoods are a bit of a joke...the front element was in a bit of state. numerous scuffs and scratches. Wide open was ok, but if I stopped down or pointed the lens into the sun then it's effects were no where as clean as they used to be. I had the front element group replaced and it cost an eye watering £350 UKP but the results were a very much rejuvenated lens. Optically, it was like a new lens again...although the outer casing looks like a well used PJ's tool.

In determination of the feasibility of a repair, what one paid for the lens originally doesn't really come into play. One only considers the cost to repair vs the cost to simply replace the entire lens at current prices.

well, maybe. If I sell the lens instead, say 1200 outright, I think it's possible someone will buy it at that price considering no scratch to the front element, only coating loss. Take that on the chin and simply buy another lens. Considering a fix for the lens with sale @1200 means that the lens only netted 732.... I could put up the lens today with coating loss and sell it in a few hours or minutes I'm sure. Canon quoted me 600+ and that's insane, but my independent local guy will charge a bit less. Since the damage doesnt affect iq 99% of the time, another option is to live with it, but it does twist my stomach everytime I look at it -?

Sure the option to sell it as is certainly exists (and was implied in my reply, I certainly wouldn't expect someone to keep the defective lens and also buy a replacement), but my reply was strictly around the $2300 - crunch the math comment. ;)

What you originally paid is moot when you are looking at the financial impact of having a lens with a defect and whether to fix, or sell and buy a replacement.

Another alternative is to join CPS if you are in the states and meet the requirements, pay the CPS annual membership, then see what the discounted repair is. Might as well send in your other equipment for a good cleaning at the same time then.

I have a CPS Platinum membership and just had the front element replaced on this lens. They claimed it was scratched and not covered under warranty. With the CPS 30% discount, I paid $428.50 for the repair (zero shipping costs).

All that gear swapping actually paid for everything I own, I paid for nothing out of personal savings. There were only 4 items in the past where I actually lost money (my first 7D, my 1D4, the sigma 50-500 OS, my 24-70 due to an unforeseen repair), but the the other items took care of that loss. This means I was able to try out countless bodies, lenses, etc over the past decade at no cost to myself. You know what they say about assumptions.... ;)
