Best travel zoom for pentax k?

For a Pentax K travel zoom, I'd start with the Pentax smc DA 50-200mm f/4-5.6 ED WR. It reaches well past the standard range, it's weather-sealed, and it stays a sensible size. If you want the lightest kit, the Pentax HD DA 18-50mm f/4-5.6 DC WR RE covers wide scenes, interiors and street shots, and it's the one I'd keep in the bag most days. For the most reach, the Pentax HD DA 55-300mm f/4-5.8 ED WR is the one to choose, but it's bigger and gets darker as you zoom in.

None of these three has image stabilisation, so shoot dim churches and interiors at a higher ISO or steady yourself against a wall. Check the travel guide for the other things that count on the road.
