Canon RF 16-28mm f/2.8 STM Lens Distortion Examined

Summary

Christopher Frost's review of the Canon RF 16-28mm f/2.8 STM lens on an EOS R5 reveals a plastic build with a metal mount and weather-sealing. While autofocus is silent and image stabilization offers 5.5 stops of benefit, the lens exhibits dramatic barrel distortion that necessitates in-camera correction, impacting corner resolution. Sharpness is good in the center, but corners are softer, especially when uncorrected. Close-up performance is capable, and flare is present but manageable.

Key points

• The Canon RF 16-28mm f/2.8 STM is a budget-oriented ultra-wide zoom with significant barrel distortion.
• In-camera correction is required for usable JPEGs, impacting corner resolution.
• The lens features silent autofocus and 5.5 stops of image stabilization.
• Reviewer Christopher Frost suggests purchasing only if found at a discount.
