[Leica] rigid summar

[Thinkofcole at aol.com (Thinkofcole@aol.com)]

for Dan Colucci, Lager's Vol. II on Leica lenses  says the rigid Summar was 
codenamed "Sumar" and introduced in 1933 while  the collapsible Summar was 
codenamed "Sumus" and followed soon after with Agfa's  introduction of a new 
color 
film process that required special filters.
    Lager adds that "factory records suggest" that "less  than two 
thousand'' 
r'gid Summars were "completed.'' He also notes that Willy  Hahne, a Leica 
historian, in "10 Jahre Leica Historica,'' says that after Leica  ran an 
item in 
Leica Photography in 1934 offering to convert rigid Summars into  
collapsible 
Summars for $17.50 [usd], "hundreds" of lenses were converted and  "explains 
in part the scarcity of the rigid Summar.''
