50mm 1.2 focus off 10ft, and on-the-money. Had similar?

Just got around to putting my new 50mm 1.2 to use. I focused on a redwood tree and wondered why it looked like the matter in focus ended up being needles on the ground 10 ft. closer to me than the tree. Took the lens to Pro Photo, and trying it on a 5D Mk iii, the guy there said he didn't find anything awkward just from a few test photos. He suggested putting my card in my 5D Mk ii, enabling the AF point display. I did that, and it was the center point as suspected, which means flipped to AF, the shot was 10 feet front focused. But with a few test shots yesterday, I also got accurate AF in my office at stuff on the wall, then then a couple feet front focus outside shooting at moss on cedar fence.

With virtually every other lens in my signature, AF works fine for me. It's only this 50mm 1.2 where I'm seeing this issue. Anyone every experienced similar?

A lens repair place the camera shop recommended, suggested sending the lens to Canon when I described what was or was not happening with both lens and camera.

I've had a couple of lenses before which were off some on focus, but nothing quite like this. Had the AF focus point indicator told me, for example on the one, that I used a focus point to the far left, i would have though operator error. But the center point and trunk should have had nothing close, not even a spider web dangling in the way.

Here's a sample ..

The green arrow is where the focus point is. The red arrows by the foliage left and path below are what's in focus. The trunk is about 11 feet wide.

Like suggested to you already, send it to Canon with everything you've told/shown us and hope it doesnt cost an arm & leg.

Not sure if it's a coincidence or not but I've had nothing but trouble with 2 different 50 1.8's and currently my new 50 1.4. I Wouldn't be surprised if the 1.2 holds up to the tainted 50mm family name.

I had an interesting route to getting my 50L

The first one I got was massively defective. It was like every shot seemed to have Vaseline smeared over the lens or something.

Returned it for another, which had a massive focus problem like you see here.

For a while I gave up and used a 50/1.4 which is a lens that kind of bothers me day to day because it has awful bokeh and it has awful focus performance in low light.

So finally I got a third 50L, which I love. My current lens is sharp and focusses with no issues.

Interesting feedback so far.

Maybe that's why the camera shop guy said issues like I'm experiencing are more common than I might realize. Although he implied hope when he suggested sending the lens in.

Mine is still well within the warranty period. I got it around last November, and really didn't put it to use until just a few weeks ago.

You did ask if anyone else had had problems, so it's not surprising you got such a response. All the people like me who have not had problems didn't post.

First try microadjusting the lens for distances like in your forest shot. If it can't be done within the range of the camera, the lens is faulty. Mine is sharp and has accurate focus at that distance. (I have an older model camera.)

As for your office tests and the test in the shop, you didn't say what f stop you tested it at. Ensure when you test that close your aperture is at f/1.2. Otherwise the known, designed-in, focus shift at close distances could cancel out the front focus on your copy. That's why I said to microadjust at longer distances.

Leaving aside any other tests when the lens behaves properly, the fact remains if it cannot be microadjusted to focus correctly for a subject like your tree above, the lens is faulty.
