The film is Fuji RHP II (I think it's a II, my eyes are getting old :-( ).
Wait, it must be RHP III, or Provia 400F. Darned, my eyes are old :-(

My bad! I did my usual webifying thing. It does make a true comparison
invalid. Here are pretty much the raw scans:
http://www.dragonsgate.net/pub/summar-np.jpg
http://www.dragonsgate.net/pub/summicron-np.jpg
Only thing done to them was to resize to smaller sizes and convert the
profile to sRGB.

The original posts (w/o the -np suffixes), were done w/ very minor
sharpening, which is otherwise always needed because the scanner softens it

ever so slightly, especially since I use ICE by default. The only other
thing I did was to Adjust Level in Photoshop and moved the high and low
points to the true ends of the histograms. I think this shows the Summicron

is a much higher contrast pic - on the summicron pic, I only needed to
nudge the end points slightly. On the summar pic, the ends of the histogram

were a bit further inward.

Anyway, I think you can tell by these two pics that the Summar is softer
and lower contrast, and does not have quite the snap. OTOH, even on the
teenager's skin, I think the Summar gives a more pleasing smooth tone. Of
course, lets leave the B word out of the discussion :-)

Oh, this particular Summar also seems to be relatively scratch free. There
is a 2-3 mm line around the center, but otherwise I don't see other
scratches or fog / haze etc.
