Glad you agree, Mike. But, sometimes I like to reduce the size and weight.
My 50/3.5 Industar-50-2 lenses would make you happy in that sense. Eensy and 2.4 oz. Another sleeper is the Canon AF
50/1.8. Seems to be all cheap plastic, rattles if you shake it, but sharp, contrasty, low distortion, low CA, etc.
I can't see any reason to pick one of these over the other, slightly different, but not in ways that would make a winner
and loser.
OTOH, neither stands out as particularly great. My initial responses were "Nice duck.", not "Great images of a nice
duck!" I've recently been doing a lot of lens testing. Although I very seldom use a tripod when not testing, I like to
separate lens performance from any limitations I may put on them through technique. So the tests are all done on a heavy
duty tripod and head, with remote release or self-timer.
With a 3D target, there's also the problem with fast lenses of focusing in the same plane for each lens. I suspect there
is a tiny difference between the focal planes of these two shots. I started this round of testing with a complex, 3D
subject, and things got unclear. With a flat target, differences in resolution and contrast are much clearer.
What were the shutter speeds? Could there be a little motion blur? Is there some way to get your editor to keep the EXIF
data in its jpeg output?
I find that the smaller ones can be made to be useful, in a pinch.
For the sizes you post, I imagine there is little noticeable difference. I bet I could post shots with Panny 20/1.7 and
Oly 25/1.7 at those sizes and no one, including me, would see a difference, even though pixel peeping at test targets
shows the Panny to be softer.

I picked the Summicron-R as the winner, with the Canon a close second.
Not even close IMHO. Summicron-R going away. Just donate the rest to charity :)
