There was a modest change in the design of the 
Rigid 2/5cm Summicron from that of the 
Collapsible lens, Luis, though Leitz/Leica has 
never given us the full story.  I believe that 
the Rigid 2/5cm Summicron is identical optically 
to the DR/NF version of that lens, the only 
difference being in the lens mount, but I have 
never researched this and that could be a third 
design based on a common pattern.

I really like the qualities available from the 
2/5cm Summitar, the 2/5cm Collapsible Summicron, 
and the 2/5cm Rigid Summicron, but all have 
distinct signatures.  In the end, I have a 
Summitar on my IIIc, a Collapsible Summicron on 
my IIIg, and a NF Summicron on my M3 DS.
