The FA 31mm is $989.95 with free shipping at Adorama.

A-squared + B-squared = C-squared

23.7 squared + 15.7 squared = C squared

561.69 + 246.49 = C squared

808.18 = C squared

C = square root of 808.18 = 28.4285068197

Outer pixels of sensor are not part of image so round up: 29mm.

Pentax DA 29mm f2 Limited - $539 = "I'll buy that for a dollar!"
