Best budget lens for the leica sl3 s?
For a budget lens on the Leica SL3-S, I'd start with the Panasonic Lumix S 50mm f/1.8. It's the fast prime my first camera guide recommends for people and low light, and it's a great first lens.
If you want one lens that covers more ground, the Panasonic Lumix S 20-60mm f/3.5-5.6 is a flexible everyday zoom. For wide scenes, the 7Artisans AF 35mm f/1.8 is a compact, good-value choice for street and travel.
I don't list prices on the site, so check current ones before you buy. You can see every lens that fits the camera on the Leica SL3-S page.
