The Mamiya-Sekor 50 mm f:6.3 for the Universal and Press 23
was the most outstanding and remarkable wide lens I've ever owned.

The lens, intended for 6 x 9, actually "almost" covered 4x5 in the studio.

And I've owned a slew of Super Angulons including: 21 mm 3.4 for M, 21 mm 4 
for R, 90 mm, 121 mm, 165 mm;
and the 58 mm SA XL - which is the only one that actually out shined the 
Mamiya.
