Is the pentax k 5 good for wildlife?
The K-5 can work for wildlife, mainly because its APS-C sensor makes every lens reach further. A 150-450mm lens frames like 225-675mm on this body, and in-body stabilisation helps when you're hand-holding long lenses. Its 16.3-megapixel sensor is modest by today's standards, so you'll want to crop less and get the framing right in camera.
For a wildlife kit, I'd look at:
- Pentax HD D FA 150-450mm f/4.5-5.6 ED DC AW, the longest reach here, like 225-675mm.
- [Pentax smc DA* 300mm f/4 ED [IF] SDM](/gear/lenses/pentax-smc-da-300mm-f-4-ed-if-sdm/), a fast prime, like 450mm.
- Pentax HD DA 55-300mm f/4-5.8 ED WR, a cheaper zoom, like 82-450mm.
Long lenses are the costliest part of wildlife photography, so buying used is a sensible way in. For more on the subject, see wildlife and sport.
