EF 85mm f1.2 L Mark II Lens Repair Question?

I have an opportunity to pick up an EF 85mm f1.2 L Mark II Lens for about 1/3rd the cost of a new one. I examined the lens and it looks brand new and doesn't have one ding, scratch or mark on it and obviously never been dropped. The problem with the lens is that neither the manual focus or autofocus works. When I put the lens on my 5D Mk III and go into the menu system the camera see's the lens as the 85 Mk II so obviously the lens is still communicating with the camera body.

The questions I have is if anyone has ever seen this type of failure and if they have I was wondering how much it might cost to fix? If the focusing motor is the issue and the cost to fix is say $400 (USD) I would jump on it in a second. If I had to put out $800-$1,000 to get it repaired then it's no longer worth it to me. I hit the $1,000 mark for the repair it would only be a couple hundred more to ge a new one that comes with full warranty. BTW, I did check and this 85mm is out of warranty. I also callled Cannon repair center and got the runaround. The only way they will give some potential costs for the repair is for me to return the lens to Canon first. Any help would be appreciated - thanks.

no other way to point out what is wrong from the internet. As long as the lens isn't water damaged, you should be ok.

Do I understand correctly that MANUAL focus does not work either?

If the lens does not stop down when the dof preview is pressed on the body, this may suggest a communication or power problem, which could be affect the AF and manual focusing as well.

If the apeture does stop down it most probably a failure of the Ring type USM motor, which I think only Canon would be best placed to fix.

I think I read somewhere that these do not have mechanical focusing. It's all electronical wizardry.


Big dreams, small wallet.

I like risks and good deals, I would jump right on it.

Go to canon's return for service form, fill it up and you'll get an estimate... I just had a 24-105L sent in with some major problems the focus would not work and the lens gets stuck at the wide end.. . The estimate was and ai ended up paying the estimate amount = 306.-

Yup, this lens uses an electronic motor drive to focus for AF or MF. That means when the camera is turned off, turning the focus ring will do nothing but spin around and not move any elements. Fly-by-wire if you will.

So My guess is your going to get it for about $650.... and say you have to spend $350 for repair =,
85L II for a grand.
I could be wrong but I don't believe the repair should be much more if the glass is ok.
Great buy and canon should give you some sort of short term warranty.

Thanks everyone for the responses. Yes, both manual/auto focus don't work but everything else seems fine. My guess was that the ultrasonic motor has died but I couldn't find anywhere that when you turn the manual focusing ring on the lens you need the motor to work for the focus adjustment to work. Obviously the electronic communication between the lens and 5D III work because the camera reads the lens when I pull up the microadjustment menu. I want one of these lenses but at $2,000 USD it's not in the cards. Looks like what I'm hearing from some of you I would be dumb to not go after this deal.

I'm confused with the question. The 85mm 1.2L II uses "focus by wire" to focus the lens. You can't put the camera up to your face and turn the focus ring and focus. The camera must be turned on and the shutter button pushed half way for the lens to focus. When the camera is turned off, the focus ring spins freely and the lens can't be retracted.

I'm only guessing here, but the owner probably doesn't know this and thinks the lens is defective. I'd buy the lens and read the manual. If the lens is indeed damaged and the focus motor needs to be replaced, Canon charges a fixed repair rate which is probably $300-$400. Add the repair cost to the bargain price for this lens and you have yourself a good deal.

What if motor is ok, but has not enough power to move the focus - because of bend mechanics?
Probably the motor has died after some time trying.

When I tested it yesterday it wouldn't focus either manually or automatically. More research this morning I discovered that the manual focus is electronically driven from the focus ring by the AF motor system. It now makes total sense why both are dead and it looks like USM failure is the primary problem.

I found one on craigslist for $800 with similar issues like your canon 85mm f1.2L.

I've encountered one of these as well. Oddly enough it was the sample Canon brought with them to their booth for a trade show, haha.
