I can't speak specifically to the 100-400 mkl.
When Canon runs out of one part, any part, they term a lens, camera, printer etc to be OUT OF SERVICE LIFE(oosl) and will no longer work on them. They might do an exterior clean, but WILL NOT go inside it. The problem becomes if they break/ruin something in/on the lens/camera, they no longer have the ability to fix it and would be responsible for replacing it with new product you may not want, thus you'll be very unhappy.
I've never sent them oosl equipment because they've told me on the phone NOT to.
Have you sent in oosl equipment that required disassembly and they repaired it internally??

Update:
I just called CPS and the good news is that the 100-400 mkl is STILL IN service life, so any repair can still be performed.
But they DID reassure that once oosl, Canon will ONLY do maintance which is limited to "clean and lube", but NO repairs! That's both for lenses and cameras.

Thanks, I thought so since they sent me the shipping labels ...

My take on your main mistake was in not sending it as soon as you got the shipping materials. Now with only a short time before your trip you might not get it back in time unless you want to pay the rather higher overnight shipping charges.

Thankfully I don't have to worry about that kind of problem, I live 21 miles from one of their main service centers and can drive there in aprx 1/2 hour to drop off and pick up.

Thank you for replying ... I don't consider making a strategic decision based on need for the equipment a mistake. Some of these connection errors are simply dirty connections or firmware issues. It is always best to attempt the simplest course of action first and then look to sending the equipment in to the manufacturer.

Clapperboard

PMW603 You mention a trip to Banff. Is that Banff in Scotland? Are you in Scotland?
I recommend Johnsons in Glasgow for lens repairs/servicing.

I had the same problem with a Sigma 80-400 when I used it for BIF and wildlife. This only happened on my 7dii not on my T1i.
I now have the same Canon 100-400 L lens as you, with no problems so far.
I am interested to hear what the outcome is for you.

The mechanical connection of the lens seems dimensionally out of tolerance. The bayonet mount can be replaced with a dimensionally correct one and should fix the problem .......

You send it in to Canon for repair. It sounds like more than just dirty contacts. There are electrical components inside the lens that may have corroded or may need repair or replacing. Let the experts determine what is wrong. Or, buy the new Mark II and get a better IQ all the way around.

Robert,

I am not familiar with a "electronic contact cleaner". Could you suggest one?

Thank you

RRS Loc: Not sure

The 7DII had one firmware update specifically for AF issues. Have you confirmed you have the most current updates applied to the camera? If yes, you should consult Canon as there should be now issues in using these two models together.

What is the most current upgrade for the Canon 7DMKII?

It is a solvent designed to clean contacts on electronic/electrical devices, most major electronic outlets will have it or go on Amazon. Home Depot, Lowes and other hardware or auto store type business will have it also. It comes in both spray cans and bottles. Two of the main features are non-conductive and that it won't dissolve the plastic parts. It also evaporates very rapidly so you don't have to wait for things to dry.
