Best budget lens for the leica sl3?
For a tight budget on the Leica SL3, I'd start with the Panasonic Lumix S 50mm f/1.8. It's a classic cheap fast prime for portraits and low light, and it's the one I'd pick first. If you want to save a little more, the Viltrox AF 50mm f/2 Air is another easy 50mm to live with. For a wider look, the Panasonic Lumix S 35mm f/1.8 suits street and everyday shooting. Skip the Leica SL lenses at this stage. They're excellent, but they're the expensive end of the list.
As my first camera guide says, a cheap fast prime does more for your pictures than a fancy body. Browse the full lenses section for more options.
