Good things about it: Cool pictures, nice bokeh,

Drawbacks: It takes a panohead and a photographer adjusting the nodal point correctly , you also need some capable stitching software and patience placing some control points in the blurred areas. And time.

...

fwiw, any comments are welcome,

I became enamored with the ultra-wide stitching back when LanceB and Brett St. Pierre showed side-by-side panos, one with the 31/1.8 Limited and the other with the 20/2.8. The 31/1.8 took many more shots, of course, but it outresolved the 20/2.8 by a good margin. The difference was startling, really. With digital stitching so (relatively) easy, why not put on a longer/better corrected lens and just stitch?

This is just another application, and I think well done.

I think that, in effect, you are doing the same thing as the 31/1.8 vs. 20/2.8 pano experiment did; namely, you are getting a shot that mimics a shallow aperture shot but with much more definition in the detailed areas. You're also getting more of a close-to-far perspective than if you had just walked 20 steps back with the SMC Tak and taken one shot.

I, however, have neither the pano head nor the patience for a 97-image stitch. So, I can't say that I would ever do it, but it certainly has me thinking.

P.S. - That Sigma 30/1.4 looks pretty sweet, too. Damn, I don't need another lens...really.
