Pentax k 70 vs pentax k 3 ii?
The Pentax K-70 and K-3 II share a 24-megapixel APS-C sensor, in-body stabilisation and the Pentax K mount, so the same lenses fit both. The K-70 is the newer camera, announced in 2016 and weather-sealed, with a flip-out screen. The K-3 II was announced in 2015 and adds GPS and pixel shift. If you want a tilting screen and weather sealing, I'd take the K-70. If you want pixel shift and GPS, the K-3 II is the one.
For an everyday kit on either body, I'd start with the Pentax HD DA 16-85mm f/3.5-5.6 ED DC WR. Add the Pentax HD D FA 24-70mm f/2.8 ED SDM WR if you want a faster standard zoom, and the Pentax HD D FA* 70-200mm f/2.8 ED DC AW for sport and portraits.
