Like someone mentioned, that 28mm pancake is a sleeper hit, but honestly there are so many amazing paths you could take! Been thinking about this for a bit and I love the variety of suggestions here. It basically boils down to how much weight you want to carry.

• For the best balance: The Canon RF 35mm f/1.8 Macro IS STM is incredible. It is light, has IS, and the f/1.8 is perfect for night street shots.
• For pure quality: The Sigma 35mm f/1.4 DG DN Art and Canon RF 24-70mm f/2.8L IS USM are fantastic if you want those professional results.
• For maximum stealth: The Canon RF 28mm f/2.8 STM is just amazing for blending into the crowd. I’d personally go with the 35mm f/1.8. It really is the sweet spot for the R6 body and gives you that extra bit of reach compared to the 28mm while being way smaller than those big L zooms. Plus the macro is a fun bonus!

My clear recommendation for Canon EOS R6: Sigma 35mm f/1.4 DG DN Art. The build quality is outstanding The build quality feels premium and should last for years.

Technical highlights: The latest generation offers significantly better image quality. Very good compatibility with Canon EOS R6 features. Can be used without problems for various photography styles. Even after hours of shooting, no performance losses. Very good build quality, even at high usage.

tbh I’m kinda surprised nobody has mentioned the Canon RF 28mm f/2.8 STM yet. I know it sounds like a weird choice compared to those fancy L lenses or the f/1.8 primes, but after reading a bunch of community reviews, it seems like the ultimate street lens for the R6 if you wanna be low-profile. Those big zooms and even the Sigma Art are awesome for quality, but they’re so heavy and people definitely notice you more, right? I'm still pretty new to this, but I feel like the R6 is already a big enough body, so putting a tiny pancake lens on it makes it way less intimidating for candid shots. It's super affordable too, which is basically what most people look for when starting out. Yeah, you lose a bit of that shallow depth of field, but 28mm is a classic street focal length that lets you tell a bigger story in the frame. Is it just me or is the smaller size way more practical for walking around all day? Just seems like a more cost-effective way to get into it without carrying a brick around.

Do you already have a preference? That could influence the lens choice.
