FAQs

Can I use this lens on a full-frame Canon RF camera?

Yes, it will mount, but the camera will automatically enter crop mode, resulting in a lower resolution image because the lens is specifically designed for APS-C sensors.

Does this lens support in-camera lens corrections?

Yes, modern Canon mirrorless cameras recognize the lens profile and will automatically apply distortion and vignetting corrections.

Is the lens weather-sealed?

Yes, it features a moisture-resistant construction to provide extra protection during outdoor use, though it is not fully waterproof.

Does this lens come with a hood?

Yes, the lens is shipped with a dedicated petal-shaped lens hood to prevent stray light from causing flare.

Can I use filters with this lens?

Yes, the lens features a 67mm filter thread, making it compatible with a wide array of circular polarizers, ND filters, and UV protection filters.

Troubleshooting

Autofocus seems hesitant or pulsing

Ensure your camera's firmware is updated. If the issue persists, try switching to manual focus and back to AF to reset the internal stepping motor.

VC system appears to not be working

Check if the VC function is toggled 'on' within your camera's menu settings or check that you are not using a tripod, as VC should be turned off when the camera is locked on a stable support.

Images look soft at the edges

Try stopping down the aperture to f/4 or f/5.6. While f/2.8 is excellent, all zoom lenses achieve peak sharpness when stopped down slightly.

Pros and Cons

Pros

  • Constant f/2.8 aperture allows for great low-light performance
  • Effective Vibration Compensation (VC) system for steady handheld shooting
  • Highly versatile focal range covering wide-angle to short telephoto
  • Compact and lightweight design ideal for travel
  • Silent and fast autofocus suitable for video work

Cons

  • Designed exclusively for APS-C sensors
  • Slight softness in corners at the widest focal length
  • Lack of manual focus clutch or physical focus limiter switch

Setup, Compatibility & Care

This lens is designed for the Canon RF-mount mirrorless system with APS-C sensors. Simply align the white mount index marker on the lens with the corresponding mark on your camera body and rotate clockwise until it clicks.

Compatibility: Ensure your camera firmware is updated to the latest version to ensure full compatibility with the lens's autofocus and internal stabilization software.

Care: Always attach the included lens caps when the lens is not in use to prevent dust accumulation. Clean the front and rear glass elements using only a professional microfiber cloth and lens-safe cleaning solution. Avoid using the lens in extreme humidity without checking that the weather-resistant mount seal is properly seated against the camera body.
