Canon L RF 20mm f/1.4 L VCM 20mm
Combining an ultra-wide 20mm perspective with a fast f/1.4 aperture, this lens excels in low light and depth-of-field control through its advanced 15-element optical design with SWC and ASC coatings. The hybrid autofocus system pairs a silent Voice Coil Motor with Nano USM, complemented by a de-clickable manual aperture ring for seamless video operation. This lens is best for hybrid shooters and professional videographers who need a weather-sealed, ultra-wide prime with virtually no focus breathing.
