So you’ve got the Canon EOS R3 sitting pretty in your bag — the camera that practically reads your mind when you’re tracking a flying falcon or a toddler on a sugar rush. But even the R3, glorious as it is, won’t strut its full potential without lenses that match its firepower. It’s like buying a Ferrari and putting dollar-store tires on it — don’t do it!
Let’s talk about the four lenses that will unlock your R3’s inner beast, with little sass and humor (because photography should be fun, not a math exam).
1. Canon RF 24-70mm f/2.8L IS USM: The Swiss Army Knife of Lenses

Imagine a lens that can shoot your cousin’s wedding, a breathtaking sunset, and your cat’s dramatic zoomies — all on the same day. That’s the 24-70 f/2.8L. It’s Canon’s one-lens-to-rule-them-all, and it does it while keeping your shots sharper than your mother-in-law’s comebacks.
The stabilization plays perfectly with your R3’s IBIS, so your handheld shots are smoother than a jazz sax solo. And that f/2.8 aperture? Chef’s kiss for low light.
You’ll Love It If…
- You want one lens that does almost everything
- You love creamy bokeh and crispy details
- You hate swapping lenses mid-shoot
You’ll Curse It If…
- You don’t have a personal chiropractor (this thing is hefty)
- The price makes your wallet spontaneously combust
2. Canon RF 70-200mm f/2.8L IS USM: The Long Lens That Laughs at Distance

This lens is what you grab when you want to turn an ordinary shot into a National Geographic masterpiece. Wildlife, sports, concerts — it’s like having binoculars that spit out 45-megapixel files.
Canon’s new RF version is almost suspiciously compact compared to old DSLR 70-200s. And that constant f/2.8 across the zoom range means your background will look like a creamy watercolor painting — even from the nosebleed seats.
You’ll Love It If…
- You shoot sports, wildlife, or love compressing backgrounds
- You want to blur everything but your subject into dreaminess
- You want fast AF that works like it’s got a sixth sense
You’ll Curse It If…
- Carrying it all day turns your shoulder into a medieval torture device
- You had plans for a vacation but spent the budget on this lens
3. Canon RF 15-35mm f/2.8L IS USM: The Wide-Angle Wonder

Ever want to capture an entire mountain range in one shot — and still have room for your dog in the corner? The 15-35 f/2.8L is your best friend. Wide but not fisheye weird, this lens makes landscapes epic, interiors grand, and night skies sparkle.
It’s also stabilized, so if you want to shoot handheld video or squeeze into a tiny space to get that ultra-wide shot, it’s got your back.
You’ll Love It If…
- You’re into landscapes, architecture, or astrophotography
- You want edge-to-edge sharpness without distortion nightmares
- You crave epic perspectives that make people go “whoa”
You’ll Curse It If…
- You think every lens should cost less than a phone
- You forget the front element needs special filters that cost extra
4. Canon RF 10-20mm f/4 L IS STM: The “Hold My Beer” Ultra-Wide

Canon wasn’t kidding around when they dropped the RF 10-20 f/4 — it’s the widest full-frame zoom they’ve ever made. It’s the lens equivalent of pulling out a selfie stick the size of a fishing pole.
At 10mm, it’s so wide you can practically shoot the inside of your fridge and the neighbor’s yard in the same frame. And with image stabilization, your handheld videos will be smoother than a fresh jar of Skippy.
You’ll Love It If…
- You’re a vlogger, landscape addict, or love creative perspectives
- You want an ultra-wide without lugging a giant fisheye
- You plan to make real estate agents weep with joy
You’ll Curse It If…
- f/4 is just a hair too slow for ultra-low-light needs
- You’re not careful — get too close and you’ll see your own toes in the frame
So… Which One Should You Actually Buy?
The 24-70mm f/2.8L is the go-to for everything — it’s like wearing jeans that fit perfectly.
The 70-200mm f/2.8L is your ticket to insane portraits, sports, or wildlife that’s 100 yards away.
The 15-35mm f/2.8L is the lens to make landscapes and interiors jaw-dropping.
And the 10-20mm f/4L? It’s for creative shots that’ll blow people’s minds (and show off your entire vacation rental in one pic).
But hey — if you can only pick one, go for the 24-70mm. It’s boring advice, but it’ll handle 90% of what you throw at it. Then start saving your pennies (and maybe selling a kidney) for the others.
