Hey everyone! I finally pulled the trigger and upgraded to the Canon EOS R5 after years of shooting on older DSLRs, and man, this thing is an absolute beast. The level of detail from that 45-megapixel sensor is incredible, but I am quickly realizing that my current lens lineup might be holding the camera back a bit. I have been using a few older zoom lenses, but they just do not seem to have that clinical sharpness or the beautiful rendering I was hoping for when I made the switch to mirrorless.
I really want to get back to the basics and invest in some high-quality prime lenses to really leverage what this body can do. My main focus is a mix of professional portrait sessions and some candid street photography when I am out traveling. I am looking for lenses that offer that wow factor—the kind of glass that makes an image pop right out of the camera.
I have been looking closely at the native RF lineup, specifically the RF 50mm f/1.2 L and the RF 85mm f/1.2 L. They both look like dream lenses, but they are also quite a heavy investment. I have also heard some people say that using an EF-to-RF adapter with older L-series glass is still a great way to go, but I am worried about whether those older lenses can actually keep up with the R5's demanding sensor and blazing fast autofocus system.
Another thing I am considering is size. While I love the quality of the L-series, the smaller RF 35mm f/1.8 macro seems like it would be much better for street photography, though I am not sure if the image quality is high enough for professional work. I have about $3,500 to spend right now and I am trying to decide if I should get one super lens or try to find a pair of slightly more affordable primes that cover more ground.
If you were in my shoes and wanted to build the ultimate prime kit for the R5, which lenses would be at the top of your list and why?

In my experience, grab the Canon RF 35mm f/1.8 Macro IS STM and Canon RF 85mm f/2 Macro IS STM. Theyre roughly $500-$600 each, super sharp, and youll save a ton. Best value duo!

Respectfully, I'd consider another option than just sticking to the entry-level primes. I mean, you bought a Canon EOS R5 Mirrorless Camera for a reason, right?? That 45MP sensor is basically a microscope. If you use the budget STM lenses, ur honestly gonna see the limitations in the MTF charts, especially wide open. I've done the market research and the resolving power on the Canon RF 85mm f/1.2 L USM is actually insane—it's literally one of the highest-rated lenses ever tested for the RF system. Tbh, I think the best move for ur $3,500 budget is to get one God-tier lens and one utility lens. If I were in your shoes, I'd grab the Canon RF 85mm f/1.2 L USM first. It gives you that clinical sharpness and the wow factor you're looking for in portraits. Then, use the leftover cash for the Canon RF 35mm f/1.8 IS Macro STM. It's small enough for street photography and the image quality is surprisingly solid for pro work, even if it's not L glass. Another thing to consider: old EF glass like the Canon EF 50mm f/1.2L USM is classic, but the AF motors sometimes struggle to keep up with the R5's Eye-AF at high burst rates. The native RF communication protocol is just way faster and more precise. So yeah, I'd definitely prioritize native RF glass to fully leverage that beast of a body. It's a heavy investment but totally worth it for the results... gl!

In my experience, making the jump to a high-res body like the R5 really changes how you look at your gear's reliability. I remember when I first switched, I was honestly pretty worried about how the transition would affect my workflow. I spent weeks debating whether to stick with my older glass using an adapter or just dive into the new system. I ended up choosing the high-end native options because I was mostly concerned about physical stability and the weather sealing points. Basically, I found that the native electronic communication and the increased pin count allow for much faster data throughput—at least I think that is how the AF stays so sticky on that sensor. My current setup feels like a tank--no wobbling at the mount and the gaskets are super tight, which is a big relief when I am shooting portraits in the rain or doing street stuff. I have used adapters before but they always felt like a potential point of failure... kinda like an extra link in the chain that could break. Honestly, for pro work, the peace of mind from a secure connection is everything. Dont skimp on the build quality if ur doing paid gigs!!

^ This. Also, just catching up on this thread now and honestly, I think we have two clear paths here. You have the camp suggesting the budget STM primes like the 35mm and 85mm, and then the other side pushing for the absolute top tier RF L glass. Both have points, but in my experience, there is a middle ground that keeps your wallet safe while still giving you that pro look. I have tried many setups over the years, and if you are worried about the R5 sensor being too demanding, don't overlook the older glass. Using an adapter is the ultimate DIY way to get high end results for way less money.
- Get a Canon Mount Adapter EF-EOS R. It is super reliable and basically makes your EF glass feel like it belongs on the R5.
- Pick up a used Canon EF 35mm f/1.4L II USM. It is way more clinical than the RF 1.8 version and handles the 45MP sensor like a champ.
- Grab a Canon EF 85mm f/1.4L IS USM. It has its own stabilization and the bokeh is just creamy. Going the used EF route lets you get two legendary L-series lenses and the adapter for under your $3,500 budget. You wont regret the build quality and you get that weather sealing which is a must for travel. Let me know if you need help finding good used sites!
