Best travel lens for the leica sl3 p?
For the Leica SL3-P, my pick for a travel zoom is the Panasonic Lumix S 24-105mm f/4 Macro OIS. It covers wide to short telephoto, which handles most of what a trip throws at you, and its stabilisation helps in dim churches and interiors.
For evenings and food, add a small fast prime. The Panasonic Lumix S 35mm f/1.8 gives a natural everyday view, and the Panasonic Lumix S 50mm f/1.8 suits tighter portraits.
If you want a Leica-branded zoom, the Leica Vario-Elmarit-SL 24-90mm f/2.8-4 ASPH spans a similar range with a wider telephoto reach. It's a premium option.
Before you buy, check the travel guide and weigh the camera with the lens on it, not the body alone.
