A long time ago I travelled through the Yucatan. Visited all of the (then) available Mayan sites, had nearly a week in Merida, and spent the
last week on the Caribbean coast letting my wife soak up the sun. And I took with me an F2 Photomic, a 24mm Nikkor, and a 55mm
Micro-Nikkor. No telephotos, no zooms. A few years later we went on a Nile cruise, followed by several days in Luxor, several in Cairo,
and a week going up Sinai, and crossing the Red Sea into Jordan to see Petra and the 7 Pillars of Wisdom. Same camera, same 24mm,
but the 55mm had by this time been swapped for a 105mm Micro-Nikkor. If I hadn't had a fascination for little things I'd probably have
substituted an 85mm f/1.8 Nikkor for either of the Micros. You can travel a lot lighter using primes, rather than zooms. I later switched to
using Leicas, and one of the best lenses I owned was the 180mm Apo-Telyt: small, and incredibly sharp. Mind you, that was used on a
full frame (35mm) camera. But I'd test one, or a lens of that focal length, on a digital.
