A new dimension of portrait performance
Designed and built to the strictest precision standards, this lens offers magnificent imaging performance throughout the frame, right up to its widest F1.4 aperture setting.

Extraordinary resolution and bokeh
Outstanding resolution even at the maximum F1.4 aperture renders the subject with impressive dimensionality. Then gradual, gorgeous bokeh dissolves the background into an artistic backdrop with natural colouration and highlights. This rare combination, due in part to new XA element technology, opens up new vistas of visual expression.

Natural images with no spurious colour
Chromatic aberration can degrade resolution as well as bokeh quality. Three ED (Extra-low Dispersion) glass elements make a significant contribution to this lens’s outstanding optical performance, keeping axial chromatic aberration in check while maximizing both clarity and the natural look and colour of its breathtaking bokeh.

Sublime 2-sensor autofocus accuracy
In addition to the usual rotation sensor, a second sensor detects focus lens group position. This dual sensor system achieves the extremely high level of focus precision that is necessary to make the most of the high-resolution potential of advanced camera bodies. RDSSM (Ring Drive Super Sonic wave Motor) drive provides the required power and speed.

Outstanding clarity and contrast
Advanced Nano AR Coating technology produces a lens coating with a precisely defined regular nano-structure that effectively suppresses reflections that can cause flare and ghosting, for notable improvements in clarity, contrast, and overall image quality.

Easy de-click for movies
While still shooters usually prefer the tactile feedback provided by click stops on the aperture ring, moviemakers favor smooth, quiet, click-free aperture operation. The click stops on this lens’s aperture ring can be easily turned on or off to suit still or movie shooting applications.
