What lenses should I buy for the pentax k r?
The K-r is an APS-C body, so every lens frames tighter than its number suggests. A 50mm, for example, acts like a 75mm on full frame. For an everyday kit, I'd start with one zoom and add a prime or two.
- Pentax HD DA 16-85mm f/3.5-5.6 ED DC WR: wide to short telephoto in one lens, and it's weather-sealed.
- Pentax smc DA 50mm f/1.8: a simple standard prime for portraits and low light.
- Pentax HD DA 15mm f/4 ED AL Limited: a slim wide for landscapes and street.
Lenses matter more than the body, so pick the ones you'll use most. If you're still deciding on the whole setup, the Your first camera guide explains the thinking.
