Pentax k 1 mark ii vs pentax k 1?
The two bodies share the same specs on this site: a 36 x 24mm full frame sensor, 36.4 megapixels, in-body stabilisation and the Pentax K mount. The main difference is timing. The K-1 was announced in 2016 as Pentax's first full-frame DSLR, and the Pentax K-1 Mark II followed in 2018 as its replacement. Both take the same lenses, so your lens choice won't change between them.
If you want the newer body, go for the Pentax K-1 Mark II. If you find a good deal on the Pentax K-1, the lens options are identical. For an everyday kit, the Pentax HD D FA 24-70mm f/2.8 is a strong standard zoom, and the Pentax HD D FA* 85mm f/1.4 suits portraits.
