Is the pentax k 500 good for wildlife?
The K-500 works well for wildlife, mainly because of its APS-C crop factor of 1.5. A 150mm lens frames like 225mm on it, so you get reach without paying for a bigger camera. The lens matters more than the body here, so start with a long telephoto. Good picks from its catalogue:
- Pentax HD D FA 150-450mm f/4.5-5.6 ED DC AW for the most reach, like 225-675mm.
- [Pentax smc DA* 60-250mm f/4 ED [IF] SDM](/gear/lenses/pentax-smc-da-60-250mm-f-4-ed-if-sdm/) for a faster, more versatile option.
- Pentax HD D FA* 70-200mm f/2.8 ED DC AW if you want the brightest lens.
For birds in flight, aim for 1/2000s or faster. That pushes ISO up, so keep an eye on noise. See Wildlife and sport for more, and Buying used if you want to try a long lens without a big spend.
