Alf, Dan: As a member of the SA  f3.4 fan club, I have a question with
regard to  distortion. We know that both the classic SA and Zeiss 38mm
Biogon  (for the Hasselblad) designs exhibit very small distortion(<<1%) and
thus  favored for architectural photography. Do you have any  information if
the newer retrofocus designs in the 21 f2.8 Elmarit or the later asph
version show such low distortion?
Perhaps Erwin has the answer.

regards, Andrew J.
