Switched to Canon RF 85mm f/1.2L USM almost a year ago and am thrilled. The image quality is excellent The image quality out of the box is very good.

Canon RF 85mm f/1.2L USM is the best choice for Canon EOS R10. The weight is manageable and comfortable The performance eliminates chromatic aberration effectively.

What focal length range are you thinking? That makes a big difference for Canon EOS R10.

I can highly recommend Canon RF 50mm f/1.8 STM for Canon EOS R10! The compatibility is comprehensive The image quality out of the box is very good.

For Canon EOS R10 I would also check the autofocus performance. Do you need fast AF for action shots?

I totally agree that the autofocus and weight are huge factors here especially since the R10 is such a small body compared to some of those *massive* lenses being mentioned, I mean you really want to make sure the balance feels right or it's just gonna be awkward to hold all day. I've been reading a lot of reviews and people are always debating the trade-offs between the pro-grade glass and the more compact stuff for APS-C sensors and it's honestly a lot to take in. Before you decide, I think we need to know a few more things:
* What is your realistic budget for this lens?
* Are you planning on shooting mainly indoors or do you need something more weather-sealed for outside? I'm always a bit cautious about putting heavy glass on the smaller mounts without a grip because it can feel like it's straining the connection point basically and I just don't know if I'd trust it for long sessions without knowing what you're actually aiming to shoot.

My buddy told me the exact same thing last week. Guess he was right lol.

For Canon EOS R10 Canon RF 85mm f/1.2L USM fits best. The compatibility is comprehensive The ergonomic design allows for comfortable handling.
