Overview

Description by Zeiss:

This compact, ultra-wide angle lens is ideal for spectacular landscape and architectural photography. And its unique field of view also offers you a range of creative possibilities when composing your photographs. Get right up close and give the impression you are in the middle of the action, extend the apparent depth of your image or highlight one object framed by a wide background – you will never get tired of the possibilities offered by an impactful perspective. The high performance of the Distagon T* 3,5/18 gives impressive image quality across the entire image field. Giving you a unique point of view wherever you go.

Floating Elements Design

zeiss_floating_elements_design
State-of-the-art camera techniques and high-resolution digital image sensors increasingly demand more from the lenses. The modern floating element design compensates aberrations of the Carl Zeiss SLR lenses at different distance settings. This is accomplished by changing the axial distance of single lens elements or element groups to each other. The adjustment of the element distance is coupled to the distance setting so that it always results in the right correction. The mechanical design of these lens elements is very complex and the workmanship must be particularly exact – both specialties of Carl Zeiss.

Excellent image quality
The Carl Zeiss range of T* lenses offers the highest possible standards in terms of performance, reliability and, of course, image quality. Quite simply, they are superior in every way. You can count on highly advanced flare control for crisp and brilliant images, for example. And virtually zero geometric distortion, ensuring precise accuracy when reproducing shapes – especially useful when photographing products and architecture.

Elaborate stray light reduction

Rich, vibrant colors are vital to creating a lasting impression. Stray light in the lens, however, would lead to a brightening of the image, which is particularly visible in shadow areas. Image contrast is lowered; the image appears dull and bleached. We combine various, elaborate techniques to reduce unwanted stray light. For example, all lens elements are coated with the famous Carl Zeiss T* anti-reflective coating. Additionally, a jet black special paint is applied by hand to all lens element edges to ensure that reflections are prevented from the start.

Carl Zeiss T* anti-reflective coating
All lens elements in SLR lenses from Carl Zeiss feature the T* anti-reflective coating and an optical design that produces brilliant pictures even in unfavorable lighting conditions. We vacuum deposit very thin, transparent coats on the surfaces of the lens elements to make them anti-reflective. Special substances, one by one, are vaporized with very high energy in a high vacuum, which are then deposited on the glass surface as a coating with precisely controlled thicknesses to achieve the desired reduction of reflections. The first coatings were applied by Carl Zeiss back in the 1930s.

High-quality all metal mounts
Noticeable quality and high value stability qualify ZEISS lenses for decades of intense use. The high-quality craftsmanship of the all-metal mounts, the easy-to-grip metal focus and aperture ring and the robust front bayonet and filter threads ensure an amazing photographic experience.

Reviews

"When used on a full frame DSLR (example above is from a Canon EOS 5D Mark II), 18mm has a very wide angle of view. Ultra-wide angles of view are great for emphasizing the foreground subject, for de-emphasizing but retaining the background (making background details appear smaller but remaining sharp) and for creating a sense of presence.

The longer I shoot, the more I love shooting ultra-wide angle focal lengths. I find it challenging to locate a composition where everything in such a wide angle of view falls into place - and challenging to find
