Reviews
SUMMARY
Christopher Frost reviewed the Canon RF 20-50mm f/4L IS USM PZ lens, evaluating its performance on both full-frame (EOS R5) and APS-C (EOS R7) cameras. The lens features a smooth and precise power zoom, ideal for cinematic video pulls with minimal focus breathing. Image quality is strong in the center, especially on APS-C when stopped down, but the lens exhibits severe distortion and vignetting at 20mm, requiring in-camera corrections. Flare resistance is below average, and while it offers some background separation, bokeh is not its primary strength.
