For Canon EOS R50 I would also check the autofocus performance. Do you need fast AF for action shots?

For Canon EOS R50 I would take Sigma 35mm f/1.4 DG DN Art without hesitation. The image quality is excellent The image quality out of the box is very good.

Long-term experience: Using Sigma 35mm f/1.4 DG DN Art for more than a year and am thrilled. Have researched for a long time and this lens was the best choice. The image quality clearly exceeds my expectations. Very good price-performance ratio, can only recommend further.

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

Depends on what exactly you want to do with Canon EOS R50. Photography or also video work?

Switched to Canon RF 50mm f/1.8 STM more than a year ago and am thrilled. The color rendition is impressive The controls are intuitive and easy to use.

tbh i'm still kinda new to all this but i've been lurking on the dpreview forums and checking out the rf shooters community a lot lately - basically trying to figure out what to get for my own r50 lol. from what i've seen most people really love the Canon RF 28mm f/2.8 STM for street stuff because it's basically a pancake lens so it's super stealthy, you know? it's also way more affordable than those big sigmas mentioned earlier which is great if you're on a budget like me. i've also seen some folks suggest the Canon RF 16mm f/2.8 STM if you want that really wide perspective for cityscapes. honestly i'd recommend checking out christopher frost on youtube - his reviews are super helpful for seeing how these lenses actually perform on crop sensors like ours. it's gonna take some practice to find what works best for you haha but those two seem like the most practical community favorites right now!

Bookmarked, thanks!

stumbled upon this discussion today while looking at sensor readout speeds. honestly, my experience with street glass on the r50 has been pretty disappointing so far. i spent a lot of time analyzing mtf charts and diffraction limits for this sensor, but the actual real-world results just didnt hit the benchmarks i was expecting. unfortunately, most of the glass i tested had significant issues with corner softness and barrel distortion that werent easily corrected in post-processing. it seems like finding that perfect balance of resolving power and compact size for an aps-c body is harder than it looks. i tried a few different setups, but the chromatic aberration on high-contrast edges was just a dealbreaker for me. before i dive deeper into the technical data i have, are you strictly looking for native glass or are you okay with the added flange distance of an adapter? also, do you prioritize low-light performance or are you more focused on getting perfect edge-to-edge sharpness for urban geometry?

For Canon EOS R50 I would take Sigma 35mm f/1.4 DG DN Art without hesitation. The controls are user-friendly The low distortion is perfect for professional photography.
