What Buyers Say
Canon RF45mm F1.2 STM 45mm
72 out of 100 medium confidence 29 reviews
This 45mm f/1.2 lens is praised for its excellent value, offering a fast aperture and good image quality at a budget-friendly price. Users highlight its sharpness, lightweight design, and ability to create beautiful background separation. However, some note significant focus shift at f/2-2.8, softness and contrast drop-off wide open, and strong vignetting before correction. It is considered a great creative tool for hobbyists but may not meet the demands of professional work or video use.
