What lenses should I buy for the leica sl3?
For an everyday kit on the SL3, I'd start with one standard zoom and one prime. The Leica Vario-Elmarit-SL 24-70mm f/2.8 ASPH covers most daily shooting, from wide scenes to portraits. For a lighter option, the Panasonic Lumix S 24-105mm f/4 Macro OIS gives you a longer reach in one lens.
Then add the Leica APO-Summicron-SL 50mm f/2 ASPH for a natural-looking prime that's great for people and street work.
Since you're buying into the L-Mount for years, it's worth checking the three questions to ask before you buy first, especially what you plan to photograph.
