FAQ
Which cameras is this lens compatible with?
The AF 12mm F2 RF-S is specifically designed for Canon’s RF-S mount cameras, including the EOS R7, R10, and R50. When mounted on full-frame RF cameras like the R5 or R6, it provides an equivalent field of view of 18mm in crop mode.
How does this lens compare to Canon’s native RF-S lenses?
This is currently the widest prime lens available for the RF-S system, offering a unique combination of ultra-wide 12mm focal length and bright F2 aperture. It fills a significant gap in Canon’s RF-S lineup, particularly for landscape and astrophotography enthusiasts.
Is this lens suitable for astrophotography?
The combination of the bright F2 aperture, excellent coma control through ED and aspherical elements, and ultra-wide field of view makes it ideal for capturing the night sky. The lens’s exceptional corner-to-corner sharpness ensures stars remain crisp even at the edges.
How close can I focus with this lens?
The lens offers an impressive minimum focusing distance of 0.2m (0.66ft), allowing you to get remarkably close to subjects while maintaining the dramatic ultra-wide perspective. This enables creative close-up compositions with exaggerated perspective effects.
What makes the autofocus system special?
The Linear STM (Stepping Motor) provides swift, precise, and nearly silent autofocus operation. This is particularly beneficial for video work and situations requiring discrete operation. The system maintains accuracy even in challenging low-light conditions.
How weather-resistant is this lens?
The lens features comprehensive weather sealing to protect against dust, light rain, and snow. While not fully waterproof, it’s built to handle challenging outdoor conditions when paired with a weather-sealed camera body.
Will this lens work well for vlogging?
The ultra-wide angle of view, combined with lightweight design (213g) and silent autofocus, makes it an excellent choice for vlogging. The bright F2 aperture also helps maintain quality in varying lighting conditions.
Can I use filters with this lens?
The lens features a standard 62mm filter thread, compatible with common screw-in filters. This is particularly useful for landscape photography where ND or polarizing filters might be needed.
What comes in the box?
The lens comes complete with front and rear caps, a lens hood, and a protective pouch. All documentation including warranty information is included.
How does it perform in low light?
The F2 maximum aperture combined with modern optical design delivers excellent low-light performance. The lens maintains impressive sharpness even when shooting wide open, making it versatile for everything from twilight cityscapes to star trails.
What about distortion and vignetting?
While some barrel distortion is inherent in ultra-wide designs, the advanced optical formula including ED and aspherical elements effectively minimizes distortion. Any residual distortion can be easily corrected through in-camera corrections or post-processing.

Overview
| Aperture Aperture, measured in f-stops, controls light entering a camera lens and affects image depth. Lower f-stops allow more light and blur backgrounds, while higher f-stops are better for well-lit, sharp landscapes. It\'s a key factor in choosing between prime and zoom lenses for desired photographic effects. |
