I do have the 90mm Rokkar which unlike the 40mm is not the same as the 90 in the Leica kit and reputedly the better of the 2.
Um, the M-Rokkor 90mm f/4 and the Elmar-C 90mm f/4 are exactly the same lens, built on the same production line in Wetzlar. The only difference is the bezel (the Minolta one says M-Rokkor, etc, and has a 40.5mm JIS filter thread, where the Leica version says Elmar-C, etc, and has a German E series thread). They even say "Made in Germany" on the base on both.
The Summicron-C 40mm and M-Rokkor 40mm f/2 (first gen) were also the same lens, but the M-Rokkor was built by Minolta in Japan and the Summi was built by Leica in Germany. Their performance is near to identical, but some people feel the Summi is better made ... It always seemed a little heavier to me. The M-Rokkor 40mm f/2 (gen 2) that the CLE came with is the same optical design but has multi coating. This lens definitely feels lighter than the Summi and perhaps isn't built quite to the same standard, but it exhibits less flare.
I've had both 90s and all three 40s over the years. I have the 2nd gen 40mm and the 90 M-Rokkors now. The 40mm is one of my very favorite lenses and is almost permanently glued to my M9 at this point. It is a great performer and weighs virtually nothing.
Leica M9 + M-Rokkor 40mm f/2
It's almost too sharp! This size rendering of this photo does not do it justice.
I think I paid about $625 for this example of the 40/2 in absolutely mint condition from KEH.com last Fall. It was worth every penny. I'd sell the CLE body and hang onto the lens if I could.
