Would the A6000 with the Rokinon 12mm f/2.0 be too wide for panoramic stitching?

I am thinking Sony A6000 with the Rokinon 12mm f/2.0 for industrial photography interiors. I am thinking about bracketing exposures. Correcting for the lens. Putting together multiple images for the dynamic range. Then stitching together three on the top row and three on the bottom row. Then correcting for the final perspective and vertical lines. Would this lens be too wide? Since I will be stitching, would you tell me to use more images with a less wide lens? I usually can not get back far enough from my subject. There is usually something in the way of my subject. Lighting is usually poor on my subject. I realize I may be the only photographer in the world with these problems. But the great thing is that I can always say, hey you, please stay out of my photograph. So I have that going for me.

I would think the distortion of such a lens would make stitching very hard.

I did not want to refer to specific software in my original posting. But. If it would be "difficult" in Lr and Ps, then would the solution be DXO Optics and AutoPano Pro? Or, would working in Lr and Ps be easier with more images from a less wide Rokinon lens?

I realize that some may think this is a software question for another section. But. I am wanting my answer to be related to the combination of the Sony A6000 and a Rokinon lens combination.

You could use a 8mm fisheye on a pano mount, the camera mounted in portrait mode.
You only need 4 shots to do 360 deg.

Then you use PTGui https://www.ptgui.com/ (external link) to stitch it together, some times you have to maunually identify the point to stitch points.

Then display it using Pano2VR

Wow. Excellent. So there is not a problem with using 8 to 12mm wide lens stitching panoramas?

I do think that some people use the word "distortion" to actually mean "what a wide angle does". And if any "real" distortion is corrected in software before the pano stitching. Then I would think I would be good to go.

Also this guy has a number on 360cites https://www.360cities.​net/profile/mikeanton (external link)

Is this what you want ? He use to use a 10-18mm Tokina lens on a 7D
Here is the how to do it

No. Not thinking 360 degree panoramas. Not really thinking panoramas at all. I am just thinking about stitching a bunch of images together to get a little wider in industrial interior cramped spaces. Maybe a single row of with 2 or 3 portrait images. Maybe double rows with 3 or 4 images on the top row and 3 or 4 on the bottom row.

I am wanting to take pictures similar to this, in places like this:

Rokinon has the 12mm 2.0 lens designed for APS-C sized sensors that would be the full frame equivalent of 18mm on the A6000. I am a little uncomfortable with this wide of a lens. But it is really small and weighs only 8.64 oz. Holy Cow. Maybe with this I would not need to stitch.

Then they have the 16mm 2.0 lens also designed for APS-C sized sensors that would be the full frame equivalent of 24mm on a the A6000. If the 12mm did not exist and was not small and light I would want this one. It weighs 25.04oz. This 24mm equivalent is the same wide angle that the Rokinon and Canon tilt shift lenses are using full frame cameras. Something like this is what I was looking for when I started looking for a wide angle prime for the A6000. This would be excellent to exterior building photographs. Just enough wide. Not too much cash. Sharper than the Sony zooms. People stitch together interior images from 24mm lenses all the time.

From what I read. Putting either of these on a tripod with F/8 and they are excellent.

get something wider and skip the stitching..... or you can try to stitch, but it'll be tough. I've done stitches with 14mm full frame, and it worked out great, but was a lot of work straightening stuff.

Oh no. Stitching in software is going to happen. Perspective correction in software is going to happen. Not sure a lens wider than 24mm equivalent is going to happen.

That looks a good photo. In that case I think you could be right with the 12mm.
Today I was at an exhibtion, tried out a Zeiss Touit 12mm.

I haven't tried doing any panos with it yet, but I just got the Rokinon 12mm f2 for my X-E2 a few weeks ago and it's fantastic ;)
