Mine has a focus issue with f/2.8 at greater than 12ft. See details and link to sample images here:

My camera is currently at Canon repair. I will retest with similar controlled setup when it is returned, and will post results. I voted.

Well I learned that I'm at the mercy of Canon's repair. The New Leaf 3 yr warranty does not kick in until after the Canon warranty expires. They refuse to do anything until then. So it's getting sent to Canon, along with evidence and detailed explanation.

I'm going to throw this out there for some input. Has anyone considered filing complaints with the Better Business Bureau? How about trying to utilize the Lemon Law? Those may be some sort of tool we can use to apply more pressure on Canon. If they don't fix the problem they're obligated to replace it.

It's on its way back to Adorama to be exchanged. Thanks to HelenOster, they agreed to grant an exclusion of the 30-day return policy. Keeping fingers crossed, the next one will not have the AF issue. IF it does, it's going right back.

I've shot some today, and while I currently don't have shots to post, the quality/consistency of the AF under certain conditions are really unequal, going from a good, normal image (if of no artistic quality whatsoever) to shots resembling those dadgummit posted not too long ago.

I have this exact same issue, I MFA the lenses at a certain distance (~ 30'), then shoot longer distances and the output is a plain coin toss.

Mine starts with 0620022.

Finally got it fixed at the Newport News repair center after I sent a lens along with the camera for them calibrate at 25 feet an f2.2.

The paperwork I got back with the camera lists The mirror, prism, AF sensor and a FPC sensor as parts replaced.

German forums already have done that and didn't find any correlation :

I can't give my SN because I don't have (at the moment) access to the notebook where I noted it.

The serial number is in the EXIF if you have an image.

Seems like there are a 15% chance to get a bad product. Have a look at the thread: Default Re: Is my new 70D bad or is this normal? Will post my serial no when body back as it does not show in exif info.

Scoobert, what lens did you sent with the camera and what did you tell them to replace all those parts.
I took mine to the NJ center this past Friday, they called me today to pick up.
When I got the camera, I took some shots right there at the parking lot and it looks worse.
I took it back and the technician use my 50 1.8 and reproduce the problem, so I left it again at canon.
I wish they'll replace the parts on mine, like they did with yours.

They didn't replace the stuff in mine on the first or second try either. The just keep sending it back as adjusted. After getting it back in 10 minutes I knew it wasn't fixed.

Then I sent it in with my 35 f/2 IS.

I got it back yesterday from Newport News and was testing it today.

It was received by canon on the 16'th. After 4 days I checked with customer service and according to them it was going through a sensor adjustment and calibration. Should be returned in two days. All they had left to do was put on the lens I sent and calibrate it to the camera. 6 days later it was still there so I called back to see what the hold up was. I was told that they were waiting on a new AF sensor to arrive but the had already changed the mirror, prism and something else (I couldn't hear).
So I am only GUESSING that they tried to do the lens calibration I asked for and couldn't get it to focus at 25 feet @ f/2.2 and starting changing things to try to get it.

The paperwork I got back with the camera lists The mirror, prism, AF sensor and a FPC sensor as parts replaced.

Toby got his back again from canon... He sent it in with a lens and tried to get them to test it at range as well. But they still didn't fix it. But admitted they couldn't fix it from front focusing from time to time. Yet sent it back to him after an "electrical adjustment"

The 10 minute mark is where they discuss his 70D.

Yes, I watch the podcast already. Toby has is camera at the same place in NJ. They sent me a email after I left asking for the pictures I took this morning after I picked up the camera.
I'm keeping my fingers crossed.
