Originally posted by gump I went with a Rokinon 16mm
Lots of people say "Every kit needs a 16mm" for the wide angle.. but I personally feel that adage is meant for full frame cameras.
With the crop factor of the K-70 considered, a 10 or 11mm would provide about the same field of view on APSC as a 16mm of full frame.
Since OP does express interest in landscape and architecture, perhaps find a nice used 10-20 Sigma or a Pentax 12-24mm to get that Ultra Wide Angle view.
