Jumping in here with a slightly different take. Quick question before I dive deep—how much of a factor is weight for you? Are you trekking miles into the backcountry for these shots, or are you mostly shooting near your vehicle or from a blind? Knowing your budget for the first couple of pieces of glass would help too. Technically speaking, that 32.5MP sensor is pretty dense, so you’re gonna want lenses that can actually resolve that level of detail. While the 100-500mm is the standard recommendation, for birds in flight (BIF), I’d seriously look at the Canon RF 200-800mm f/6.3-9 IS USM. The extra reach is a total game-changer because it lets you fill the frame without having to crop into your pixels too much. For landscapes, everyone talks about the 24-70, but I’d point you toward the Canon RF 14-35mm f/4L IS USM. It’s lighter, wider, and the edge-to-edge sharpness is basically industry-leading for a zoom. **TL;DR:** Grab the Canon RF 200-800mm f/6.3-9 IS USM for wildlife reach and the Canon RF 14-35mm f/4L IS USM for landscapes. Use the adapter for your EF glass as a stop-gap, but native Nano USM is way snappier for tracking birds.

Congrats on picking up the R6 Mark III – it features a newly developed 32.5 megapixel full frame sensor and 40fps continuous shooting, making it an absolute beast for action photography!

For your first lens, I'd strongly recommend the Canon RF 24-70mm f/2.8L IS USM - it's considered a staple lens and among the best Canon lenses in terms of image quality, offering exceptional versatility with a wide aperture for professional results. It provides about 5 stops of image stabilization, which when combined with the R6 Mark III's IBIS gives you 8 stops total for impressive low-light performance.

If you're looking at primes, the Canon RF 50mm f/1.2L USM is considered the best prime lens for the R6 Mark III, providing a solid balance of versatility and image quality. While it's big and heavy for a 50mm prime, the image quality makes it all worthwhile.

What type of photography are you most interested in? That'll help narrow down the recommendations!

As a portrait photographer, I'm really excited about pairing this body with some of Canon's RF primes. The RF 85mm f/1.2L DS is spectacular for bokeh, and with that Register People Priority feature that can track up to 10 different people, it should make group portraits much easier.

Also considering the new RF 45mm f/1.2 STM that launched alongside the camera – under $600 for an f/1.2 is incredible value!

Good to know!

Watching everyone talk about these RF lenses really takes me back to when I first tried switching systems years ago. Its funny how we get so caught up in the specs and the glass when sometimes the gear just has a mind of its own, and in my experience, the transition phase is usually where the most chaos happens. My cousin actually tried a similar jump from EF to a mirrorless setup a while back and it turned into quite the ordeal:

• He bought three different third-party adapters because he didnt trust the first one.
• One of his favorite older telephotos actually got jammed on the mount during a trip to the Everglades.
• He ended up spending more on overnight shipping for repairs than he would have on a brand new native lens. He never did get those bird shots he wanted because he was too busy fiddling with the mount in the middle of a swamp while the sun was going down. I still see that old lens sitting on his shelf like a trophy of what not to do. Honestly, he still talks about that trip every time we grab a beer. Anyway, just a bit of food for thought while youre deciding on your kit.

Same boat, watching this

Street photographer here! The 32.5MP sensor with 40fps sounds perfect for capturing decisive moments. I'd go with:

RF 35mm f/1.8 IS Macro – compact, sharp, great for everyday carry
RF 50mm f/1.8 STM – classic focal length, affordable, lightweight

The improved low-light performance should make these even more versatile in challenging conditions.

Hey there! Congrats on the R6 Mark III, that's a sweet upgrade! I totally get the RF lens overwhelm – been there, done that. So, wildlife and landscapes, eh? Here's my take, based on my own experiences with similar shooting.

Honestly, for birds in flight, especially in low light, you're gonna want something fast. I'd suggest looking at the Canon RF 100-500mm f/4.5-7.1L IS USM. Yeah, it's pricey, but the image stabilization is incredible, and the reach is fantastic for birds. Plus, it's an L lens, so the build quality and weather sealing are top-notch. I've used it in some pretty gnarly conditions, and it's held up beautifully.

Now, about adapting your old EF 100-400mm... it *can* work, and the adapter is a cheaper short-term solution, sure. But from what I know, you're gonna lose some of the speed and responsiveness of the R6 III's autofocus system. It's just not optimized for EF lenses like it is for RF. So, I would advise against it in the long run. Bite the bullet and go native RF when you can. You'll honestly notice a huge difference in performance, especially with BIF.

For landscapes, the RF 24-105mm f/4L IS USM is a great all-arounder. It's sharp, versatile, and relatively compact. I use it a ton for general travel and landscape stuff. If you want something wider, you might want to consider the RF 15-35mm f/2.8L IS USM, but that's another big investment. The 24-105 is a good starting point, I think.

If I were prioritizing, I'd grab the RF 100-500mm first for your wildlife needs, then the RF 24-105mm for landscapes. That’s just my personal preference, though! Hope this helps and good luck with your new camera!

Hey! Congrats on the R6 Mark III! Okay, so, adapters are a tricky thing, right? I think, personally, whether you adapt your EF 100-400mm really depends on what you *dislike* about it. Is it sharpness? Autofocus speed? Weight? If it's just 'old', an adapter *might* be okay, but honestly, the RF lenses are designed to work *specifically* with the R6 Mark III's features.

For birds in flight, autofocus speed is king, and native RF lenses will almost always outperform adapted EF lenses in that area. A decent option, if you're on a budget, might be the RF 100-500mm L. It's not cheap, but it's amazing. If you want to go cheaper, there are third party options too. I would ask around about those though, because I haven't used them and heard mixed reviews!

For landscapes, almost any lens will work if stopped down, so that's less of a concern for prioritizing initial purchases, IMO. Good luck!

Hey! Congrats on the R6 Mark III upgrade. It's a fantastic camera! I've been shooting Canon for, well, let's just say a *long* time, and I've definitely been through the lens upgrade struggle.

So, everyone's got their favorite lenses, but let's talk about bang for your buck, especially since you're coming from EF lenses. I think the adapter question is crucial, but maybe not in the way the previous reply focused on. It's about cost *now* vs. cost *later*, and how much you're willing to spend initially.

**Option A: Adapt and Wait:** Keep your EF 100-400mm with an adapter (Canon's official one is reliable) and save up for a top-tier RF telephoto *later*. **Pros:** Least initial cost. **Cons:** You're still using older glass, and the adapter adds bulk. Image quality won't be *quite* as good as a native RF lens, especially with the newest R6 III sensor.

**Option B: Mid-Range RF Zoom Now:** Sell your EF 100-400mm and put the money towards a mid-range RF telephoto zoom, like the RF 100-500mm f/4.5-7.1L IS USM. **Pros:** Native RF lens advantages (faster autofocus, potentially better image quality, smaller size). **Cons:** Still a significant expense, and f/7.1 at the long end isn't *amazing* for low light, especially with birds in flight. You might miss the wider aperture of some of the faster primes.

**Option C: The 'Hidden Gem' - RF 600mm f/11 or 800mm f/11:** I've got to be honest, this is a bit of a wildcard, but hear me out. For birds in flight, *reach* is king. These lenses are surprisingly good for the price. They're fixed aperture, so not ideal for changing light, but paired with the R6 III's amazing IBIS and low-light capabilities, they can be killer for daytime shooting. Plus, they're lightweight! **Pros:** Incredibly affordable for the reach. Surprisingly sharp. Lightweight. **Cons:** Fixed aperture (f/11). Requires good light. Not as versatile as a zoom.

Honestly, for your situation, I'd lean towards **Option A** to start. Get the adapter, see how you like your EF 100-400mm on the R6 III, and then make an informed decision about which RF lens to invest in down the line. It gives you time to research and save. Then, when you're ready, sell your EF lens and put that money towards the RF lens of your dreams!

Hope this helps! Let me know if you need more info.

Hey! Congrats on the R6 Mark III! One thing I haven't seen mentioned is *safety*, especially with wildlife and those pricey lenses. Think about lens hoods – absolutely essential for protecting your glass from stray branches while you're trekking, and even just from accidental bumps. I’ve scratched a lens before because I was too lazy to put the hood on, and honestly, it’s a gut punch.

Also, consider a good, sturdy camera strap. Those little straps that come with the camera? They're okay, but if you're lugging around a long telephoto, upgrade! I’ve almost dropped my camera more than once with the stock strap when bending over to get a shot. BlackRapid makes some decent ones, or Peak Design. Think about rain covers, too – sudden downpours can happen anywhere! Better safe than sorry, right? So yeah, while everyone’s recommending specific lenses, don’t forget to protect your investment (and your camera!).

Hey! I'd consider Sigma or Tamron RF lenses too; they often offer great value, especially for telephoto zooms. Adapting your EF 100-400mm is a decent option to start, but native RF glass will generally give you better performance overall. Something to think about!
