Just a quick counting the number of native, still in production full frame lenses that are available now for the Pentax K-1. from 15mm all the way to 560mm: not bad at all, lor!
I think another FF lens still in production but often forgotten by many, that will be Pentax FA 35/2.
Added FA50/1.4 to the list too.
