Hey everyone — I’m trying to figure out the best landscape lens for my Canon EOS R10 (RF mount) and I’m getting a bit overwhelmed by options.
I mostly shoot hiking trips and national parks, so I’m after something wide enough for big vistas but also sharp across the frame for things like tree lines and mountain ridges. I’m currently using the RF-S 18-45 kit lens and it’s been fine, but I’m noticing the corners get a little soft when I’m shooting wide, and I’m often wishing I could go wider than 18mm for dramatic foreground-to-background shots.
A couple details/constraints: I prefer something that isn’t huge since it’ll live in my backpack, and I’d like to stay around $500–$800 if possible (open to used). I’m also not sure how much I should prioritize image stabilization on the R10 for handheld landscapes, especially at sunrise/sunset.
Given the R10’s APS-C crop, what RF or RF-S lens would you recommend as the best all-around landscape option, and why?
> I’m also not sure how much I should prioritize image stabilization on the R10...
Warning: don’t assume IS = sharp pics—I learned the hard way; I got satisfied results only after using a tiny tripod/rock + slower shutter, cuz wide corners + wind + hiking jitters will ruin their detail!!!
TL;DR: I ended up happiest with a small Canon wide-angle zoom + IS, bought used, and I stopped caring about super-fast apertures for landscapes.
Story time: I was in the same R10 hiking loop and yeah… my kit zoom’s corners were kinda mushy wide open too, especially on tree lines. I tried a tiny wide prime first (cheap, light), but honestly I missed zoom flexibility a lot. Swapped to a compact Canon wide zoom with stabilization and it was way more usable at sunrise when I was too lazy to set a tripod. Unfortunately, IS didn’t magically fix corner softness—stopping down to like f/8-ish did. Also used prices were a lifesaver (saved me a couple hundred). gl!
hey, been there… on my R10 I’d pick Canon RF 16mm f/2.8 STM (tiny, sharp stopped down). If you want zoom flexibility, Canon RF-S 10-18mm f/4.5-6.3 IS STM beats kit corners; IS helps at sunrise, tbh.

I’d agree the ultra-wide zoom route is the “live in the backpack” answer long-term, honestly. Quick tips from owning the R10 setup for a while:
- Don’t sleep on filter + system cost: with Canon RF-S 10-18mm f/4.5-6.3 IS STM you can run cheap 49mm CPL/ND, which adds up way less than bigger glass over time.
- For corner sharpness, I’ve found the bigger win is just shooting f/7.1–f/11 + enabling in-camera lens corrections (distortion/vignetting). It’s not sexy, but it’s the consistent “looks sharp everywhere” fix.
- IS is nice for framing and slower shutters, but for sunrise/sunset I still treat it like a bonus, not a guarantee, you know? If you want one lens you won’t outgrow, that 10-18 + stopped down is sooo solid, right?
I totally agree that stopping down to those middle apertures is the way to go if you want the edges to look decent. Im still learning the ropes with my R10, but after doing some side-by-side tests on my monitor, I noticed that relying too much on the digital lens corrections can actually make the corners look a little mushy because of how the software stretches the image to fix the wide-angle distortion... So even if the glass is technically sharp, the processing might be fighting you a bit. Its something I never noticed on the back of the camera, but it really shows up when you crop in at home. Like, maybe try shooting a few frames with the corrections turned off just to see what the lens is actually doing? Just a thought from someone else trying to get those vistas looking crisp!!!
