Leica summilux sl 50mm f 1 4 asph 2016 vs sigma 50mm f 1 2 dg dn art?

The Sigma is the faster lens. Its f/1.2 gives you more light and a shallower background than the Leica's f/1.4, and it works on both Sony E and L-Mount bodies. The Leica only fits L-Mount. The 2016 Summilux-SL is the first version and weighs over a kilogram, so it's a heavy lens to carry all day. If you're in the Leica system and want the lighter option, look at the 2026 redesign, which is smaller and lighter.

For most people, I'd pick the Sigma 50mm f/1.2 DG DN Art. It's the better low-light lens and more flexible across camera brands. If you want a cheaper starting point, the first lenses guide covers the 50mm f/1.8 that many people start with.
