I might stay onboard and enjoy the return trip.
Here's a sample taken with my March lens, Vivitar 28mm 1:2.0 MC Close Focus Wide Angle (Komine) - It's a manual focus A lens from the 70's
Here's a quoted review:
"Ok, so what's the verdict?
This is really an outstanding lens. The close focus is remarkably useful and, combining that with f/2 and a decent OOF PSF, this lens can produce bokeh that are way better than most 28mm lenses can deliver.
Where things are in focus, they're sharp -- even wide open. Stopping down even a little improves the already-modest vignetting, and immediately improves both contrast and colors.
Colors aren't bad even wide open, but they get a little more accurate and slightly colder when stopped down. Distortion is minimal, and I really don't see any flare problems either."
