Best travel lens for the sigma fp l?
For the Sigma fp L, I'd start with the Panasonic Lumix S 24-105mm f/4 Macro OIS. It covers wide to short telephoto, which handles most travel pictures on its own. It also has OIS, which matters here because the fp L has no stabilisation in the body, so dim churches and markets are easier handheld.
If you want one lens for nearly everything, including distant subjects, the Panasonic Lumix S 28-200mm f/4-7.1 Macro OIS stretches further, at the cost of a slower aperture at the long end.
For evenings and food, pack a small fast prime. The Panasonic Lumix S 35mm f/1.8 is a good companion to a zoom and is the classic travel pairing.
The Travel guide explains how to weigh the lens with the camera and why one zoom plus one prime is the classic kit. The full list of lenses that fit the camera is on the Sigma fp L page.
