Whoops!  Just gave the image circle information for the 65mm rather than 
the 47mm.  The 47mm Super Angulon has an image circle of 123mm.  There is 
no information in the f32 lens specs. section for the 47mm f8 Super 
Angulon.  If you are able to supply the specifications then I'll add the 
info. to the table.



All the best,
