In my experience, ur gonna LOVE the Panasonic Lumix G 20mm f/1.7 II ASPH.! it has insane center sharpness. technically it hits that 40mm equivalent—perfect for street. tho the AF is kinda slow compared to the Olympus M.Zuiko Digital 17mm f/1.8, that f/1.7 aperture is AMAZING for low light. it literally stays on my Lumix 90% of the time. its tiny and sooo sharp. gl!

Seconding the recommendation above! That 20mm is sharp but the AF lag is SO frustrating... I’ve missed critical moments because it just hunts, which is why I’d actually point you toward the Panasonic Leica DG Summilux 15mm f/1.7 ASPH. instead. It’s basically my go-to for street because the rendering is just better, plus it’s wide enough for landscapes while staying fast for low light. Unfortunately, I had issues with heavy chromatic aberration on the Panasonic Lumix G 25mm f/1.7 ASPH. which was really disappointing, and a lot of these compact primes have poor edge sharpness wide open anyway. Honestly, the 15mm is a safer, more professional bet for a lens that stays on ur camera 90% of the time. gl!

Curious about one thing: what's your actual budget? Honestly, just look at Sigma... they're the best value if you want pro results without the brand-name markup. I've used 'em for years.

honestly i spent way too long overthinking this exact thing when i first started. i eventually settled on a weather-sealed prime that i basically glued to my camera for a whole year. what i learned is that reliability is way more important than having the absolute sharpest glass in the world. i remember hiking in some really misty, damp weather and being the only one not worried about my gear because i knew my setup could handle it. having that peace of mind let me actually enjoy the trip instead of constantly babying the lens. my current setup has been through plenty of drops and bumps, and it still nails focus every single time. for me, the best lens is the one you know is gonna work every time you pull it out of your bag... its less about the technical specs and more about that trust factor.

Late to the thread but i just had to jump in because i went through this exact struggle last year! Honestly, i spent way too many nights browsing forums and looking at side-by-side comparisons before i finally pulled the trigger. While everyone loves the pancakes, i found that the Olympus M.Zuiko Digital ED 25mm f/1.8 is the real MVP for daily use. I took it on a trip to Kyoto and it basically never left my camera... the colors are just so punchy and the autofocus is lightyears ahead of that Panasonic 20mm. If you're looking for that pro look on a budget, you seriously need to look at the Sigma 30mm f/1.4 DC DN Contemporary. It's a bit larger than the tiny pancakes but that extra light you get from f/1.4 is absolutely incredible for indoor shots of friends or family. It's usually way cheaper than the Leica stuff too.
