One zoom or one prime? Answer this first
Every travel lens question reduces to this trade, and there is no universally right answer — only a right answer for how you travel.
A zoom if your trip is unrepeatable. A week in a city you will not return to is not the time to discover you cannot frame the cathedral. A 16-55mm on APS-C covers 24mm wide to 82mm tight, which is the range almost every travel photograph actually lives in. You pay for that in money and in roughly 230 g over a prime.
A prime if your trip is long or your back is the constraint. A 265 g Sigma 30mm f/1.4 on a crop body gives you a ~45mm equivalent — close to how your eye frames a scene — plus two full stops more light than an f/2.8 zoom, which is the difference between hand-holding a lit street at night and not. You reframe by walking, which is what you were doing anyway.
The honest middle path is one zoom and one fast prime, and if that is your plan, buy the zoom first. A prime-only kit will frustrate you on exactly one day of the trip; a slow-zoom-only kit will frustrate you every evening.
Full-frame travel: wide and light, not wide and heroic
On Sony full-frame the Tamron 17-28mm f/2.8 is the pick, and the reasoning is deliberately unglamorous. You give up the last 3mm of width against a 14-24mm, and in exchange you get 420 g, a constant f/2.8 and a 67mm screw-in filter thread. For travel, those three things beat the extra millimeters every time: the polarizer you can actually fit is worth more than a focal length you will use on two frames.
It focuses to 0.19 m at 17mm, which matters more than it sounds on a trip — it lets a wide lens double as a close-up lens for market stalls and food, so you are not carrying a macro as well. There is no optical stabilization, so you are relying on your body’s IBIS or a surface, and the lens is Sony E only. If you want one full-frame prime instead, the FE 35mm f/1.8 at 280 g is the better travel choice than a 50mm: 35mm is wide enough to show where you are standing, and on an APS-C body it becomes a ~52mm everyday lens if you later switch.
Fujifilm travel: the one weather-resistant pick
The XF10-24mm f/4 R OIS WR is the only lens on this page that combines optical stabilization, weather resistance and an aperture ring, and for travel that combination is worth more than a stop of aperture. A 15–36mm equivalent range covers the big landscape and the tighter composition, so on a hike it can genuinely be the only lens you carry, at about 385 g with a conventional 72mm filter thread.
The cost is f/4 rather than f/2.8, which shows up after dark, and Fujifilm publishes no stop rating for the OIS on its own specification page — so we are not going to quote one. If night shooting is a priority for your trip, pair it with a fast prime rather than expecting one zoom to do both.
What to carry, by trip
City break, three to five days. One standard zoom. The 16-55mm on APS-C or a 35mm prime on full-frame. You will walk twenty kilometers a day and change lenses never.
Hiking and landscape. One wide-ish zoom with a filter thread and a polarizer screwed into it: the XF10-24mm on Fujifilm, the 17-28mm on Sony full-frame. If the trip is specifically about landscapes rather than travel generally, our landscape lens roundup ranks the ultra-wides properly.
Long trip, one bag, mixed subjects. One fast prime on the body, one zoom in the bag. The Sigma 30mm f/1.4 and the 16-55mm is the classic APS-C pairing and weighs 759 g together — less than many single full-frame standard zooms.
Travel video. The FE 35mm f/1.8 or the 16-55mm, both of which have fast, quiet autofocus that does not record itself. Our video lens roundup goes further into focus breathing and parfocal behavior.
The specifications that matter on a trip
Weight, with the body. Add the lens weight to your camera and then imagine it on a neck strap for ten hours. A 494 g zoom on a 377 g body is 871 g; the same body with the 265 g Sigma is 642 g. That 229 g gap is the difference between a camera you take out at dinner and one you leave in the room.
Filter thread, and whether it is a common size. 67mm and 72mm are everywhere and cheap. A lens that needs an 82mm or takes no filter at all means a second purchase, and on a trip that means no polarizer.
Closest focus. Travel photography is half landscapes and half details — the food, the tile, the hands. A lens that focuses to about 0.2 m saves you from carrying a second lens for that; one that stops at 0.4 m does not.
Maximum aperture, for evenings not for blur. On a trip the practical value of f/1.4 or f/2.8 is hand-holdability after sunset, not background separation. If you want to understand how much light each stop is actually worth, see aperture, explained, and prime vs zoom lenses for the full version of the trade above.
One thing that is not on that list: ultimate corner sharpness. Every lens here is sharp enough that the limiting factor on a travel photograph will be the light, the moment and whether you were carrying the camera at all.
