Canon RF 16mm
Reddit take
AI summary of the Reddit excerpts below — not a quote
The Canon RF 16mm f/2.8 is a polarizing ultra-wide prime lens that is highly regarded for its portability and value, though it is frequently criticized for its optical compromises. Users generally agree that while it is sharp in the center, it suffers from significant corner softness and distortion that requires software correction. It is often described as a 'fun' or 'travel-friendly' lens rather than a professional-grade tool.
Pros
- Extremely compact, lightweight, and pocketable design
- Affordable price point for a native RF ultra-wide lens
- Good center sharpness, sometimes outperforming older EF zooms
- Effective for casual wide-field astrophotography and Milky Way shots
Cons
- Poor sharpness and image quality in the corners
- Significant native distortion and vignetting
- Noticeable coma and distortion issues for serious astrophotography
- Build quality and performance may feel like a 'starter' lens rather than a long-term investment
Caveats
- Relies heavily on in-camera or post-processing digital corrections to manage optical flaws
- Performance on APS-C sensors (like R7/R10) is viewed as particularly compromised by some users
- Mixed sentiment regarding its indoor low-light performance despite the f/2.8 aperture
Best for
- Travel photography where weight is a primary concern
- Casual hikers and landscape enthusiasts on a budget
- Vlogging or wide-angle street photography
Avoid if
- You require edge-to-edge sharpness for professional architectural or landscape prints
- You are looking for a high-end 'forever' lens with minimal optical distortion

The RF 16mm f/2.8 is slightly sharper than the EF 16-35 II at 16mm.
I have made one exception so far: the RF 16mm f/2.8 appealed to me, because a small, light ultrawide is really useful for what I do.
RF 16mm f/2.8 - cheap (around £215 grey market or used), tiny and native, but a little wider than I'd like Although the RF 16mm does not get the best review, but it would amount to the 24-27mm equivalent for landscape usage. I'd suggest to start with either of these and see if you'll use them at all. The 16mm is ofcourse very pocketable
You may want to look at the RF 16mm or the RF-S 10-18mm which would give him the flexibility of a zoom.
For wider FoV you will want something like a short prime, again f/1.8 or f/2.8 is your best bet for lower light performance: the RF 16mm and 28mm will do that pretty well
option 2 mirrorless : EOS R10 with RF 16mm and RF 100-400mm
The 16mm prime doesn't review exceptionally well in general from my research
It's very good in the center and amazingly bad in the corners. If you can live with that it's fine!
It’s my favorite lens for wide field Milky Way shots. I haven’t used it for a single other thing since I got it but it was well worth the money spent.
The photos shot with the 16mm were way better than the 28mm ones.
