This is one of the most celebrated lenses in the history of rangefinder photography. The Canon 50mm f/1.4 was designed to compete directly with Leica's own Summilux. It earned its legendary status by being remarkably sharp even when shot "wide open" at f/1.4, featuring a 6-element "Planar" style design. Its heavy brass construction and smooth-as-silk focusing make it a tactile joy to use, especially when adapted to a Leica IIIf.
Curator’s Notes
The "Infrared" Mark: You’ll see a small red "R" on the scale. This is for infrared photography. Because IR light focuses at a slightly different point than visible light, you would focus normally and then shift the focus ring to line up with that "R."
The Infinity Lock: The beautiful scalloped "infinity lock" lever. This allows you to lock the lens at infinity focus, which also serves as a convenient handle to help you screw the lens onto the camera body.
Optical Character: The warm amber glow visible in is the signature of this lens. It provides a "vintage" look that digital filters can't quite replicate—high center sharpness with a gentle, glowing fall-off at the edges.
