Description

Smooth and reliable autofocus

The design of the autofocus system requires an extremely accurate shifting of particular lens groups. The focusing system of ZEISS lenses is designed to ensure a robust and smooth-running autofocus mechanism with the best imaging performance.

Versatile full-frame lens

The powerful lens for the mirrorless full-frame system of Sony fulfills the highest requirements. Despite its compact design, the image meets the expectations of professional photographers.

Excellent resolution and high contrast

Richly saturated and vivid colours are a must in the creation of lasting impressions. However, stray light within an optical system leads to a lightening of the image that is particularly noticeable in the shadows. This reduces image contrast, with the result that exposures lack contrast and appear faded. To avoid this, ZEISS combines various specially developed technologies to reduce the undesirable effects of stray light.

Robust and weatherproof metal construction

Thanks to features that are designed to keep out dust and spray water, the lens is perfectly suited for critical outdoor conditions. It is also designed for many years of intensive use.

Innovative OLED display

For the first time, you can accurately read the focus distance and depth of field simply and intuitively on the OLED display on the lens. Especially in poor light conditions – excellent readability is always guaranteed.
