Is there an extraordinary wide-angle for mirrorless? Or using a DSLR lens with an adapter?

The distortion may also be an issue with inexperience making them or going from 12-24 or a combination there of I can't say of course.
It is odd that you can't turn off the Distortion correction.
Have you tested it side by side with another lens? Samsung says 99 degrees for the 12-24 which should be the same as other lens' in theory.

The distortion cannot be disabled when using 12-24mm, 16mm, 20-50mm, etc. Before the corretion maybe it is 99 degrees, but after the corretion, it is not that wide.

I just made a quick measurement with my tripod and the scale on the ballhead and focus near infinity...

...and it is slightly more than a 100 degree diagonal in the RAW file...

...from the 12-24 mm lens @ 12 mm, if used with a NX1000 and ACDSee Pro 7.

Other RAW converters restrict the FOV more.

Thus, the stated 99 degree is a bit conservative.

I guess that it is about 102 degree if a optimized test with real pixel peeping etc. is performed.

I compared samsung 12-24mm with canon 5d2+1635 ii. After the correction, 1635 at 18mm is wider than samsung 12mm. I love samsung 12-24, I just hope that we can disable the correction in the camera, then it is good enough for me.

You probably compared them, using LR or PS and not with ACDSee Pro 7?

LR does not allow You to use the RAW uncorrected, but ACDSee does.

-

The correction in the camera, is just metadata with instructions for RAW converters (and in camera JPG and preview pictures)...

...within LR You can not bypass, but within ACDSee You can.

However, I also wish that it is always possible to turn the lens correction off. Within the camera and within converters.
