Pentax k 3 mark iii vs pentax kf?
The K-3 Mark III and the KF are close cousins. Both are Pentax DSLRs with a 1.5x APS-C sensor, in-body stabilisation, and the same lens list. The main spec difference is resolution: the K-3 Mark III has 25.7 megapixels, against 24.2 for the KF. The KF is the newer of the two, announced in 2022 against 2021 for the K-3 Mark III. If you want the extra resolution, I'd go with the K-3 Mark III. If you only shoot black and white, the K-3 Mark III Monochrome is the one to look at.
You didn't say what you shoot, so here's a sensible everyday kit that works on either body:
- Pentax HD DA 16-85mm f/3.5-5.6 ED DC WR for most things.
- Pentax smc DA 35mm f/2.4 AL as a small standard prime.
- Pentax HD D FA* 85mm f/1.4 ED SDM AW for portraits.
