1) Does it focus to infinity?
Yes
2) Does the focus ring stop at the infinity mark or extend past it?
Not tested
3) Does your copy sit perfectly secure when attached to camera with no movement when using the focusing ring, or does it 'wiggle' or rotate a little bit back and forth?
Snug, no looseness detectable
4) Bonus question: Did your copy arrive with the lens in a vacuum sealed plastic wrap?
Yes
Such images as I have taken with the 12mm Laowa have been satisfactory.

Thanks for the feedback, Presto. Just when I thought I might settle for this second copy that also has this looseness, and didn't come sealed, you've helped me step back in the other direction. Three months of dealing with this, what's another month! haha

Ok some answers about my copy.


Could you tell me a few things about your copy? (Same questions go out to anybody here who also has the Laowa 12mm)
1) Does it focus to infinity?
Yes
2) Does the focus ring stop at the infinity mark or extend past it?
It stop at the end of infinity 8 sight, and it focus properly = that position is not softer that previous
3) Does your copy sit perfectly secure when attached to camera with no movement when using the focusing ring, or does it 'wiggle' or rotate a little bit back and forth? (Please visit my thread linked above if I am not making sense, since there is a video to demo the 'problem' or 'behavior' might be a better word)
Wiggling as on your video.: it exist, but it exist with almost all my lenses. Sigma EX II 70-200 2.8, DFA 50mm macro FA 31mm 1.8. Only lens that ar very stiff is DFA 24-70. But in my case amplitude of Laowa is much smaller than your copy.
4) Bonus question: Did your copy arrive with the lens in a vacuum sealed plastic wrap?
Yes I bought mine straight from China as there is no official polish seller.

only one things. If lens is @ A position, lens is making sound during montage @ camera like trrrrr. if aperture is set on lens no sound is made
Second: only original back lens cap is not loose. All mine caps is falling out but is that a big issue?
there was somewhere questions abut quality. Picture quality.
In my opinion flare is biggest issue.
Resolution?
You have to use Pixel Shift to check it
Here is PS shot developed in Raw Therapee 5.1





Are the corners worse than center? yes
Are they softer Yes
But still very good considering size and FOV.

Thank you for the feedback. I had no idea how common it is for lenses to not be snug fitting in the mount. All my other k-mount lenses fit snuggly. Both copies of the Laowa I've had now have been satisfactory on the other marks for me, and I think the flare control is good enough. Here are some of my snaps from the weekend with the Laowa 12mm.

Here two samples of using the 12mm lens as a 19mm shift lens (no software correction of converging lines needed by simply keeping the lens aligned to horizon):

My Sigma 12-24 on my K-1 at 12mm. I will admit that 12mm is pushing it for this lens. You really need a tripod but that is not always possible.
