Best telephoto lens for the pentax k 1 mark ii?

For most telephoto work on the Pentax K-1 Mark II, I'd start with the **Pentax HD D FA* 70-200mm f/2.8 ED DC AW**. It's fast enough for low light and tight portraits, and it's a strong all-rounder for sport and events.

If you need more reach for wildlife, the Pentax HD D FA 150-450mm f/4.5-5.6 ED DC AW goes much further, at the cost of being bigger and slower at the long end.

For something lighter, the Pentax HD D FA 70-210mm f/4 ED SDM WR is a sensible choice if you'll be carrying the camera all day.

The wildlife and sport guide covers how to choose between reach and speed.
