Originally posted by Giklab Come on man, you're comparing with Zeiss?
Absolutely.
When I was looking for a standard lens on APS-C K-mount,
my three top candidates were the FA 31/1.8, DA 35/2.8, and ZK 35/2.
The FA Limited lost out against the second
because of its built-in FF hood and lack of Quick-Shift.
It lost out against the third because it wasn't sharp enough at f/2.
Originally posted by Giklab Oh yes, most other brands don't have such primes.
It wasn't clear whether the OP's question was restricted to K-mount lenses.
If you include other mounts, let's say DSLR to be fair,
you also have to include Leica R ("Leitax-able" to K-mount), Canon L, Nikkor G, . . .
