A refined double-gauss design incorporating two aspherical elements, including one precision AA (advanced aspherical) element, works with an ED (Extra-low Dispersion) glass element to suppress field curvature and distortion while maintaining outstanding image-wide resolution and contrast from the widest aperture at any focusing distance.
F1.4 for versatility and beautiful bokeh
The F1.4 maximum aperture can be used to create images with shallow depth of field and smooth, beautiful bokeh. A bright maximum aperture like this also makes it possible to shoot at high shutter speeds in low lighting. Of course the lens can be stopped down to create extended depth of field when required.
11 blades for natural bokeh highlights
Although Sony’s circular aperture design usually employs up to 9 blades, this lens incorporates 11 blades that take bokeh quality to new levels of smooth beauty. Natural looking highlights in the out-of-focus areas enhance overall atmosphere while providing a gentle sense of depth.
Excellent colour and contrast
ZEISS lenses are renowned for their outstanding colour reproduction and contrast. The ZEISS T* Coating is an important contributing factor, effectively suppressing spurious reflections that can degrade overall image quality. Flare and ghosting are reduced for enhanced colour and contrast that give images a deep, three-dimensional feel.
Autofocus that supports high resolution
Focus drive is handled by a RDSSM (Ring Drive Super Sonic wave Motor) system that is capable of positioning the heavy focus group required by large aperture lenses with speed and precision. Fast, accurate focus is essential to bring out the full performance potential of high-resolution camera bodies, whether you’re shooting stills or movies.
Convenient fingertip control
A physical aperture ring allows intuitive aperture control. An aperture click switch makes it possible to enable or disable the aperture ring click stops as required. Moviemakers will want the clicks OFF, while photographers often prefer tactile click feedback. There’s also a focus mode switch for convenient manual/auto focus selection.
Reliable in challenging conditions
A sealed dust and moisture resistant design provides extra protection and ensures reliable operation in challenging environments. Shoot with confidence in light rain or windy conditions.* *Although the design is dust and moisture resistant, absolute protection from dust and moisture is not guaranteed.
