Comment:

Like it's slower sibling, the extraordinary Apo-Summicron-M 1:2/50mm ASPH, this remarkable lens is on par with the much larger and heavier Zeiss Apo Distagon T* 1.4/55 Otus, proving that highest-precision manufacturing and unrivaled expertise in optical engineering can produce lenses that are both compact and exceptionally good. Impressive, and well worth the premium price.
