Is the pentax kf good for wildlife?
Yes, the KF is a good wildlife body, and the 1.5x crop helps. A 450mm lens frames like 675mm on full frame, which is the reach wildlife needs. The body also has in-body stabilisation, which steadies those long lenses handheld.
For the KF, I'd start with these:
- Pentax HD D FA 150-450mm f/4.5-5.6 ED DC AW for the most reach.
- [Pentax smc DA* 60-250mm f/4 ED [IF] SDM](/gear/lenses/pentax-smc-da-60-250mm-f-4-ed-if-sdm/) if you want a faster lens and can work closer.
- Pentax HD DA 55-300mm f/4-5.8 ED WR as a lighter, cheaper option.
Wildlife is hard whatever you shoot with, so read wildlife and sport first. Long lenses also hold their value well, so buying used is a sensible way in.
