Best wide angle lens for the pentax k 70?

For a wide angle on the Pentax K-70, my first pick is the Pentax HD DA* 11-18mm f/2.8 ED DC AW. It's fast for a wide zoom, and on the K-70's APS-C sensor it frames like 16-27mm on full frame, which covers most interiors and landscapes.

If you want the widest view, go for the Tamron SP AF 10-24mm f/3.5-4.5 Di II LD Aspherical (IF). It's the classic APS-C landscape lens, framing like 15-36mm on full frame. The landscape guide explains why a wide zoom suits big skies.

For something smaller and simpler, the Pentax HD DA 15mm f/4 ED AL Limited is a prime that frames like 22mm and is light enough to carry all day.
