Except that in the process the lens got damaged. That could be construed as a waste of effort.
If the adaptor was not bad it would be worth the effort.

Totally agree. I'm very happy with my adapted FL / FD lenses with third party chips and Magic Lantern on my T3i, all of which are non-standard things, but they work really well. However, if something breaks it is my problem, not Canon's.
I think the OP is being treated very well by Canon. STM lenses are totally electronically controlled, manual focus-by-wire and so on, I can fully appreciate how a third party unsupported adapter could screw things up.
A lesson to others.

The A6000 is a whole different animal, its a crop sensor camera and will match up with the EF-S lenses. But the A7R II is a 42MP Full Frame, EF-S lenses are a total waste of effort on that camera, which is the one you stated you were using. (You cannot even mount them on Canons OWN full frame cameras) That's why I had to ask, why?
Yes you can mount some EFS lenses and use them on the A7RII, with some vignetting at some zoom focal lengths. But I'm not going to try any more of these lenses (I still have a 18-135 that worked fine) with the King adapter.

Smiling at you! However placing the lens on the adapter was not an "experiment" the lenses are listed as compatible by the manufacturer of this adapter. I insist I did not "misuse" my equipment, I was simply using it as I had every reason to believe it could be accomplished without risk.
Until I reported this, no one else had reported this problem on the appropriate forums. You see the fence I approached had been reported to non electrified...

OK. Then the issue is with the King adapter. Have you had any response from them?
Not wishing to to be harsh myself, but these things occur, and it is usually ourselves that absorb the risk!
Good luck, and take care!

Can't find King (they are in China, of course). Canon has been beyond great..I still don't understand the policy of repairing one lens for free even if I don't repair the second one. Maybe I can sell on Ebay and someone else can try to get a free repair!

I had a really good laugh when reading that. Having grown up on a farm with many electric fences, I did exactly that when about 5 years old and it was an experience I still remember vividly 70 years later. For you city folks that have never seen an electric fence, urine is an excellent conductor of electricity. The current isn't strong enough to be fatal or physically injurious, but is it ever painful!
On a more serious note, I seem to recall, perhaps inaccurately, that Sony make lens adapters for the A7R II? If so wouldn't those be less likely to cause problems than a third party maker?

I thank you for the info and appreciate Canon more now. Too bad Nikon can't understand customer service.

I wonder if the rep still has her job? Sounds like she kind of screwed things up. You were supposed to pay $144 total for both lenses being repaired. All you asked was that the worst lens be returned un-repaired. She ends up twisting it around so you will get that bad lens back and the better lens repaired for free. Yep, she's been fired.
The question now is, have you received the lenses back yet, or, did they realize their mistake and will be contacting you shortly with a "revised deal"?

This post brings up something I hadn't worried about. What kind of electrical/electronic stuff is inside of a lens. Is the some kind of memory chip inside. If there is a 'reset', then the chip would have to be RAM, but that make its data contents liable to variability which makes no sense. So the chip is most likely a ROM, for which 'reset' makes no sense. To are semiconductor experts here - can the firmware on a ROM be reprogrammable (easily).
Would any adapter be 'benign' in the sense it just lines up the contacts right and the mounting breach right. The lens on my Sony a6000 has 10 contacts. Might posters particular adapter be made with the connectors mis-wired - as in a manufacturing error for that one item. From what happened, I would think the adapter manufacturer should be liable. Will keep that maker in mind.
This last makes me think there should be a list of crappy manufacturers and sellers somewhere.

She actually let me choose which lens to have repaired for free. I immediately received the 55-250 back and have already replaced it with a new version I purchased for $159 with free shipping on Ebay! Fingers still crossed on the 10-18mm...It wouldn't surprise me if they contact me and tell me it can't be fixed....now to list the damaged lens on Ebay for parts.

The Sony a7rii can use either crop or full frame lens just like some of the Nikons. If you use a crop lens then your pixel count drops from around 40 to 18.
I've used a couple of adapters on the a7rii that I rented and they worked ok.
I wish Sony made a better lens lineup. Using adapters is a pain.

After looking up the King adapter on Amazon, it stated that although the adapter was compatible with the 55-250, it does not advertise that it is compatible with the STM version.

I'm a little surprised Canon would fix them at all, let alone at no cost. I'm sure any warranty was completely voided by misusing the lenses in that way.
It's all about marketing. Canon knows these stories get out in the photographic community.
I played around with legacy and other-platform lenses and adaptors when they were all still manual focus. I stopped doing that because it made no sense to me to fiddle with off brand lenses. I can't even imagine risking the electronics in the lenses, or the camera, to get full performance from either.
If the native lens selection does not suit me, I will just go another way.
This is an example of the risk. Sony needs to get on track with some lens selection. I am intrigued by their performance in the bodies, but will probably never buy on until the lens inventory expands.
However, I also suspect the lens inventory now in place is as good as any other mfrs. native lens selection is to their own bodies, ie. Canon to Canon.
BTw, I consider Canon Lenses somewhat over rated.
