The lens’s optical design minimizes aberrations at wide open, delivering crisp detail and beautiful, creamy bokeh that enhances subject separation and visual impact.

The combination of fast AF and accurate manual override gives you full creative control in dynamic situations.
• L-series build with premium optics: built to Canon’s professional standards, this lens features robust construction and high-grade glass designed to deliver exceptional contrast, color fidelity, and minimal distortion across the frame. Its design supports reliable performance in varied shooting environments, from bright studio setups to challenging outdoor scenes.
• Natural perspective with close focusing: at 50mm with a minimum focusing distance of 0.40 m (1.31 ft), you can framing portraits and details with a natural perspective that flatters subjects while still capturing environmental context when desired, making it a versatile choice for bloggers, documentary photographers, and creators who love a wide palette of framing options.
• Versatile accessory compatibility: the generous 54 mm front filter diameter accommodates a wide range of filters and accessories, enabling you to control reflections, contrast, and color balance. The design also supports the use of polarizers, ND filters, and other front-mounted accessories without compromising image quality or focus performance.
