We just got back from a tour of Grand Canyon and Utah national parks. Here's a shot late afternoon at Zion National Park, with a storm brewing in the north. The cloud formations were stunning. It was about 100 degrees F in the shade.
This was shot with the humble 18-135 WR at 28mm and a circular polarizer. It was also hand-held at 1/30 sec. I was really pleased with its output. A great travel lens and so easy to carry around. I took some limited primes with me, and the 15mm was nice to have along and the 35 macro for close ups, but really I could do a whole trip with just the 18-135 next time if required. Would just have to beware of the long end beyond 115mm at infinity/distance and not expect too much at 18-20mm depending on the scene. Otherwise it does pretty much everything well.
Anyhow, it was a fun trip and we saw some amazing places we'd never been to. I'll post some more later.
