A sweet lens, sharp all the way and with good bokeh.
Teamed with the 45mm f/4 it was my walk-around lens.
Its main purpose, the one for what it has been designed, is the portraiture.
But it has proven a great landscape lens too.
Its only fault, one that in my opinion it shares with all the lenses in the Pentax 67 lineup I’ve used, is the lack of a “spark” that the Zeiss for Hasselblad lenses have, and the Pentax don’t.
Otherwise, or if your tastes are different than mine, definitely a keeper.
