I still think that is underestimated lens.

Goa. Pentax K1 still funny: if you move from 70 to 35 mm lens is getting longer :).
@ 70mm

@ 35mm

This lens have a lack of hard contrast but a lot of micro contrast. What is great in digital time when contrast is not a issue during processing.
Colors also are great.
So this is happines: toys from my childhood. If you squeeze them they make funny cracky sound.

Pentax K-1 and Sigma 70-200mm F2,8 EX DG OS HSM works nicely

Hi every one. I bought Sigma 70-200/2.8 EX DG Makro HSM II. As it was 2009 version obviously need service to work on K1.
So I send it with K1 to Sigma Service centre. At the end it cost me 520 USD for lens and around 50 USD for maintenance, changing motherboard and Lens calibration. Bayonet change for free :)
I'm very happy with my combo. AF is sometimes hunting very fast :) AF-C is like in K1 so almost no hits if something is walking running at your position.
My question is: what TC if any could work properly. I checked and sigma data show that sigma TC is not working with this lens:
Lenses | Sigma Corporation of America
So question is what is working?
Best!

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.

TS adapter is available only for mirrorless as it they short flange distance.
ofc. you could modify image from fish but it always lossy in term of resolution and sharpness. I now learning how much I could "shift" lens in Capture 1. I've tried do same correction in DxO but it give me much more losse of resolution.
I envy canon 17mm T/S.

Hi this time some small technical post. Precisely post production. I have FA 20mm 2.8. Very like this small lens. But it have some hat field curvature. very annoying.
I've tried manual correction systems in different programs. DCU, Lightroom, Silkypix, RAW Therapee. And best was in Silkypix as only this program have two stage correction. But I was still only half way solution.
I'm still playing arond with C1. I've got suggestion from GetDPI forum to use Pentax 21mm lens. But it is profile for APSC camera. So it not give me what I wan't. Next step was find something most similar.
So I go to sony lenses department and tried Sony 20mm 2.8 SAL20F28 set distorion on 120% and got it!.

Very best correction I could get:
