I guess I will have to run another roll through it with the 28 on it and see what I get. Although I use it all the time on my M8 and love the results.

The 28 Elmarit 2.8 ASPH appeared to be designed for the M8 not the Summicron - its performance drops in the corners when used wide open on a 24x36mm frame as you can see on the MTF chart linked from here: http://us.leica-camera.com/photography/m_system/lenses/2194.html. The 28 Summicron is sharp right out to the corners, and has a very flat field. H. Ball Arche, who used to use a 28 a lot and posted here prolifically, didn't like the flat field because it made heads in the corners of the frame look like footballs - he preferred the C-V 28/1.9 which had greater barrel distortion and a less flat field, but less apparent distortion of things like heads in the corners. A nice display of the compromises optical design includes. The 35 Summicron ASPH was designed during the film era and in some ways doesn't perform as well as the 35 Summilux ASPH II with the floating element, but it's still pretty formidable. On the M8 I prefer a 28 to a 35, but I think generally I prefer a 28 overall, even if it is the Nikkor 28mm f1.4 which is actually a ~31mm lens. After Leica revises the 50 Summicron (now the oldest lens in the M line up and the only Summicron without aspherical element(s)) the 35 and 90 ASPH Summicrons are probably next, because they are the oldest.
