Pros & Cons
Pros
- Lightweight and compact, making it easy to carry around for travel and casual photography.
- Affordable price point, typically around $200, making it accessible for beginners.
- Decent performance for landscapes, especially with digital lens corrections in post-processing.
- Good for astrophotography, providing a wide field of view and acceptable performance in low light.
- Short minimum focus distance allows for creative close-up shots and environmental portraits.
Cons
- Notably weaker corner sharpness and optical aberrations, particularly coma in astrophotography.
- Reliance on digital lens correction to address distortion and vignetting, which can affect image quality.
- Focus motor is not as fast as USM or L-series lenses, potentially impacting performance in dynamic environments.
- Quality may not meet expectations for users transitioning from higher-end lenses, leading to some disappointment.
Verdict
Overall, the Canon RF 16mm f/2.8 STM lens is seen as a solid option for casual users and beginners looking for an ultra-wide angle lens at a budget-friendly price. While it has some optical shortcomings, particularly in corner sharpness, it performs well in landscapes and astrophotography with the right corrections.

Frequently Asked Questions
How does the RF 16mm f/2.8 STM perform for astrophotography?
It offers a wide field of view and fast f/2.8 aperture, making it a solid budget choice for night sky shooting. However, coma and soft corners are present, so results are best for casual Astro or social media use rather than critical, large prints.
Does this lens have weather sealing or image stabilization?
No, the RF 16mm f/2.8 STM lacks both weather sealing and image stabilization. It should be used with caution in harsh environments, and for stabilization you must rely on a camera body with IBIS or use a tripod.
Is distortion a problem on this lens?
Native barrel distortion is significant, but modern Canon cameras and software correct distortion automatically for JPEG and supported RAW workflows. For best results, always enable digital corrections.
What cameras is the RF 16mm f/2.8 STM compatible with?
It is designed for Canon's full-frame mirrorless RF-mount cameras, including EOS R, R5, R6, RP, R8, and R50 (with crop). It does not fit EF-mount DSLRs or older EOS-M cameras.
How does this lens compare to the RF 15-35mm f/2.8L?
The RF 16mm f/2.8 STM is vastly smaller, lighter, and cheaper, but doesn't match the optical quality, build, or flexibility of the RF 15-35mm f/2.8L. The 16mm prime is best for size- and price-conscious shooters.
Can I use filters with this lens?
Yes, it takes standard 43mm front screw-in filters, making it easy and affordable to use ND, polarizing, or protective filters.
