Shoot with a JSK Super Angulon 21mm 3.4 and you'll get 35mm format Biogon
quality as its a true symmetrical wide angle lens. The only reason why its
not competitive with the Biogon on the Hasselblad is the format is smaller.
And its not a square format.

Also check out the 2.1cm f/4-16 Nikkor-O for the 35mm format.
A true wide angle used with an SLR with its mirror locked up and  a
viewfinder but it was also made for the Nikon rangefinder camera.

Check out these schematics on true wide angle glass illustrating the:
Hypergon, Topogon, Hologon, Biogon and Dagor.

The Super-Angulon can be seen here with all the other JSK profiles.
