Hi! I'm a long-time reader and first-time poster.
I just did an indoor test of all my 50s, from wide open down to f/5.6. The lenses are:
Summicron Rigid
Canon 50/1.8 LTM (chrome)
Elmar 50/2.8 LTM (the old Elmar)
Summitar (10-bladed, coated)
Summar
Sonnar 50/2 (Zeiss Jena, collapsible, uncoated)
Jupiter-8
Canon 50/1.5 LTM
Sonnar 50/1.5 (Zeiss-Opton, coated)
They were on my M3, with Ektar 100.
Here's the set on flickr:

Some observations:
- I'm not sure that the scans necessarily kept all the highlights (some look a little blown out). These are just machine scans from a (good) local lab.
- The ghosts opposite the flashlight are really interesting. All of the double-Gauss lenses have fairly prominent ghosts, but none of the Sonnar designs do.
- The Summicron seems to show the most detail and contrast, especially on the meter stick.
- The uncoated lenses, though lower in contrast, did surprisingly well for sharpness and resolution.
