I asked because I’ve seen so many focal lengths, apertures, small, large, but no discussion of what type of subject,/shooting environments, what style, or type of images were of interest.
The question "What lens for travel" or 'What body?" is incomplete. We can answer guessing universal or individual context or play 20 Questions. That broader context is important. I try, at least sometimes, maybe unsuccessfully, to add some location or other context, to my "recommendations." I wonder a bit if maybe that's tiresome (he's mentioned Switzerland and Rhine River cruise in every gear post for the last two years).
I have a couple of constraints. (Somewhat universal?) One is I can't afford all the goodies I might want. Another is I can't afford to go to all the places I might want. Travel "time" either "when" or "how long I can "travel"" is limited. I can't carry everything. That might be physical around the destination or just getting to and from the location. Travel by myself will be different than travel with others (at least for me.) Travel by air differs from travel by car
I tend to zooms, probably for both "convenience," budget and habit. I'm not against primes. I don't have many, not in the habit of using just one or two and usually expect/want coverage for more and different things.
Getting past all that?
Location: (A) I live in Southern California, driving distance, within reason, sort of, to a wide variety of locations. Usually I'll be shooting "outdoors" in natural areas. This tends to push me to longer focal lengths. (B) Some trips, urban centered, say "old cities," congested streets, large buildings - exteriors and interiors where one may not be able to back up far enough and that pushes, not exclusively, to "wider." That said, I like those "details," that steeple top, a statue as "portrait,' across the roofs from a high point.
Style "A" 28-200 works quite well as an "only" but more likely foundation choice. "Style "B" the 20-70. Going back, not too long for some of us, prehistoric for the younger ones? The f2.8 "professional, "Holy Trinity" zooms and/or the very best primes ruled the high end and consumers followed along, less expensive primes or variable aperture zooms. 3X zoom range was kind of the accepted quality boundary
The 28-200 or 18-135 sorts in aps-c allowed one to go from 3 to 2. A bit later, the 20-70 allowed a different 3 to 2. More recently, the 20-200 became a potential "One lens!"
I'd think San Francisco or New York or Washington, DC will be similar in contest to Paris, London, Rome, etc. Ground travel between various cities, through countryside, mountains and/or nature, birds and animals, will be similar, too.
