Honestly, grab the Sigma 45mm f/2.8 DG DN Contemporary. It is tiny, weather-sealed, and feels like a true street lens. Way better than carrying heavy glass all day long.

Just catching up on this thread. Honestly, I tried the Lumix 35mm and honestly I was kinda let down by the build quality for the price. It felt a bit plasticky and the autofocus hunted way more than I expected in lower light. If you want something that actually holds up for daily street work without breaking the bank, skip those and look elsewhere.

• Sigma 45mm f/2.8 DG DN Contemporary for a super compact, vintage-style street kit.
• Panasonic Lumix S 50mm f/1.8 because its surprisingly cheap and sharp enough to get the job done. I ended up grabbing the 50mm because it was a fraction of the cost, and honestly, the extra reach helps me stay more candid. The gear is nice but dont overthink the sharpness charts too much. Just get out and shoot.

^ This. Also, honestly, I had a rough time with some of the lighter lenses myself. I tried the Panasonic Lumix S 35mm f/1.8 and unfortunately the build just didn't hold up for me after a few weeks of daily carrying. It wasn't as good as I expected for the price, and I've had issues with the focus reliability when things get chaotic on the street. If you want something built like a tank that actually works every time, look at these instead:

• Leica APO-Summicron-SL 35mm f/2 ASPH: Yeah, it is expensive, but it is built to survive anything and the reliability is unmatched.
• Voigtlander APO-LANTHAR 50mm f/2 Aspherical: Manual focus is actually great for street if you learn zone focusing, and you never have to worry about AF motors dying. Quick tips:
• Always carry a spare battery if you use AF lenses.
• Use a half-case to protect the bottom of your SL2-S from scuffs. Hope this keeps you from wasting money like I did.

TL;DR: The Sigma 35mm f/2 DG DN Contemporary is way more fun for street. Lumix is sharp, but that aperture ring on the Sigma just feels better for quick street adjustments.
