Impressive Speed and Sharpness
G Master Resolution and Bokeh
- Three XA (extreme aspherical) elements effectively control astigmatism, field curvature, coma, distortion, and other spherical aberrations for a high degree of sharpness and accurate rendering.
- Nano AR Coating II has been applied to reduce surface reflections, flare, and ghosting for increased contrast and color rendering in strong lighting conditions. This updated coating is better suited for larger, curved elements and is especially adept at minimizing internal reflections.
- Floating focus mechanism helps to ensure optimum and consistent sharpness throughout the focusing range.
Exceptional Speed and Versatility
- Normal 50mm focal length suits a variety of subjects and shooting applications, ranging from portraiture and street shooting to landscapes, lifestyle, and architectural subjects.
- Truly impressive f/1.2 maximum aperture yields extremely shallow depth of field results for separating subjects from busy backgrounds using selective focus.
- Beyond depth of field control, the f/1.2 design also benefits shooting handheld and working with faster shutter speeds in low-light conditions.
- Rounded 11-blade diaphragm helps produce a smooth and circular bokeh quality.
Fast and Precise AF
- XD (extreme dynamic) linear motors deliver high thrust to efficiently move larger, heavier elements and focus groups, such as those needed to produce an f/1.2 lens. This focusing system also achieves accurate focus when working with extremely shallow depth fo field effects.
- Internal focusing design offers more responsive focusing performance and maintains a consistent overall lens length during operation.
- Minimum focusing distance of 1.3' suits making dynamic close-up images.
- A close minimum focusing distance, maximum magnification of 0.17x, and bright f/1.2 aperture help create shallow depth of field imagery with a strong close-up subject and a soft background.
Compact and Durable Design
- Despite the wide f/1.2 maximum aperture, complex optical design, and inclusion of a high-performance AF system, this lens manages to still be relatively compact and lightweight for everyday handheld use, measuring 3.4 x 4.4" and weighing 1.7 lb.
- Two focus hold buttons are featured on the lens barrel for intuitive tactile control and rapid access to select settings.
- Physical aperture ring can be de-clicked for smooth, silent aperture switching to benefit video applications.
- Dust- and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures.
- Fluorine-coated front element resists dust, moisture, and fingerprints and is easy to clean.
