I, too, have one. Lovely lens, if a bit impractical. Actually, I don't find the pre-set to be that much of a problem in use.
Neither me. You learn to "count" the stops (or half-stops).
And, yes, it is not multi-coated, but on a long lens, flare isn't such a problem as on a wider lens - just don't point the lens into the sun.
If you do get one, make sure it comes with the lovely leather case, large screw-on hood, and especially, the honking big embossed metal AOC lens cap! frank
And the tripod mount, Gasha. There is a version with a tripod mount and one without. I would take the one with tripod mount (you can also take it out).
I compared its quality with Pentax-M 200mm f/4, probably at f8 and sun was coming from the back (no flare issue), and I could not see any evident difference out of a 2700 dpi scan. Maybe a very slightly better contrast on the M lens.
