The super wide-angle lens for a new era, 18 mm, f/2.8 – f/22, M77 x 0,75, 330 g
Very large field angle and fast autofocus – combined with protection against dust and spray water for reliable photography in all weathers: this is the ideal full-frame lens for landscape, astro and architectural photography.
The very large field angle of this super wide-angle lens is perfect for creative shots with unusual perspectives. Consistently excellent image quality right into the corners makes the lens perfect for the challenges of, for example, landscape, astro and architectural photography.
The ZEISS Batis autofocus lenses were specially developed for mirrorless full-frame system cameras from Sony. The lenses are fully compatible with all E-mount cameras and offer not only fast, quiet autofocus, but also protection against dust and spray water. For creative photography, the innovative OLED display shows the distance and depth of field to ensure that the focusing range can always be perfectly set. The result: images that will amaze you. The completely new design of the high-speed ZEISS Batis family offers perfect image quality.
<b>Design</b>
Originally developed for SLR cameras in which, due to the mirror box, a long back focal distance is required for short focal lengths (the distance between the back lens element and the film plane must be considerably longer than the focal length), the Distagon lenses (retrofocus design) are also ideal for mirrorless system cameras thanks to their optimized ray path. This also enables excellent image performance with large image angles for digital camera systems without mirrors.
<b>Features</b>
<b>Smooth and reliable autofocus</b>
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.
<b>Versatile full-frame lens</b>
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.
<b>Excellent resolution and high contrast</b>
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.
<b>Robust and weatherproof metal construction</b>
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.
<b>Innovative OLED display </b>
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.
