Huh? Lots of things under 21 mm eq. What about the Nikon 12-24mm f/4G
ED-IF AF-S DX? It has a good rep. I know Tom Scales loves it. The
calculator in my head says 1.5 x 12 = 18 mm FF eq.
And the Canon 10-22 is 16 mm eq. Then there's the Sigma 10-20 and the
Tamron 11-18 and Tokina 12-24.
I don't know about distortion, but all those come in at between 15 and
19 mm FF eq. at their short ends

How about the Nikon 10.5 mm fisheye.? I believe some Nikon software
converts the images into linear form. Certainly other software exists to
do that.

This shouldn't be such a big issue. Software like PTLens can nicely
correct the distortion. Cheap and easy too. PTLens has profiles already
for all these super wide zooms and will apply them based on the EXIF,
you don't have to do anything yourself

If you feel like getting your hands dirty with manual adjustment, you
can use ImageAlignPro or LensDoc. I think LensDoc did a better one step
job with the example posted above because I could correct the tilt at
the same time, but the Demo is limited on what you can take out of it.
And CSPS2 has distortion correction tools as well, Filter=>Distort=>Lens
Correction.

I'm not touting any camera or lens brand, just pointing out what appear
to me to be limitation in your lens info and thinking about current tools.
