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

Honestly, everyone here is recommending top-tier L glass, and while they're amazing, I totally agree that the 24-70mm mentioned earlier is the standard for a reason. But if ur starting out with the R5C, you've already spent a ton on the body, right? I've seen a lot of folks in the community getting incredible results without breaking the bank on every single lens. Here are a few budget-friendly gems that the community usually raves about for this setup:
* Canon RF 35mm f/1.8 Macro IS STM – Super light for gimbal work and has great stabilization. Perfect for video.
* Canon RF 24-105mm f/4L IS USM – If you find this used, it's basically half the price of the f/2.8 version and still plenty sharp for 8K.
* Canon Mount Adapter EF-EOS R – Seriously, don't sleep on old EF glass. It's the best way to save cash while building a kit. Tbh, the R5C is such a power-hungry beast. Saving some money on the glass means you can actually afford the V-mount batteries or extra media you're definitely gonna need. (at least thats what worked for me)

To add to the point above: honestly, it really depends on whether you are rigging this thing up for video or just shooting stills. I have been using the R5C since launch and my experience has been... interesting, to say the least. If you are doing a lot of handheld video, the Canon RF 24-105mm f/4L IS USM is actually a sleeper hit. I know everyone wants the f/2.8 glass, but when I was shooting a wedding last summer, having that extra reach and the stellar IS was way more important than a stop of light, especially since the R5C handles noise so well. Another one that surprised me is the Canon RF 35mm f/1.8 Macro IS STM. It is tiny, which is great because the R5C is already a bit of a brick with the cooling vent. I used it for a street photography project in Chicago and the autofocus was snappy enough to catch basically everything without weighing me down. Are you planning on using an external power bank or a dummy battery for longer shoots? Knowing your power setup and what you are actually filming or shooting—like weddings versus studio work—would help narrow it down tho.
