Product Overview

The Biogon T* 2,8/21 ZM offers outstanding performance and extreme resolving power even when shot wide open, with virtually no distortion, excellent control of flare and ghosting and superb contrast rendition across the entire frame. The slim lens design is easy to grip and focus, and uses a standard 46 mm filter diameter similar to many of the other ZM lenses and allows filters to be interchanged between the lenses. The lens is rangefinder coupled for easy focusing and the optional 21 mm viewfinder is available for accurate image composition. The Biogon T* 2,8/21 ZM is suitable for many different wide-angle applications including reportage work, landscape and architectural photos.

The range of ZEISS 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.

Dramatic perspectives and a view from extraordinary image angles – ZEISS lenses open up new composition possibilities. Distortion would disrupt the composition because straight lines, whose image does not go through the image center, would be reproduced with a curved shape. This annoying effect is accordingly and largely compensated through elaborate optical designs at all focal lengths.

The optical elements of ZEISS lenses feature T*® anti-reflective coating on all surfaces and an optical design that guarantees images of superior brilliance at all times, even in unfavourable lighting conditions. We apply the anti-reflective coating to the lens surfaces by the vapour deposition of extremely thin, transparent layers on the glass. In this process, special substances are vaporized with extremely high energy in a high-vacuum environment and are subsequently deposited on the glass surfaces, one after another, as layers with precisely controlled thicknesses to achieve the desired reduction of reflective properties. The first coating techniques were employed by ZEISS as long ago as in the 1930s.

FAQs

What makes the Zeiss Biogon 21mm f/2.8 lens suitable for landscape photography?

The Zeiss Biogon 21mm f/2.8 lens is particularly well-suited for landscape photography due to its outstanding resolving power and minimal distortion. This lens captures sharp details across the entire frame, ensuring that even the most intricate elements of a landscape are rendered beautifully. Its robust flare control also allows for shooting in various lighting conditions, making it a reliable choice for capturing expansive vistas.

How does the T* anti-reflective coating enhance image quality?

The T* anti-reflective coating significantly improves image quality by reducing unwanted reflections and enhancing light transmission. This coating ensures that the lens performs optimally in challenging lighting situations, such as backlighting, by minimizing flare and ghosting. As a result, images exhibit greater contrast and clarity, contributing to the overall brilliance of the photographs.

Can the Biogon 21mm lens be used for architectural photography?

Yes, the Biogon 21mm f/2.8 lens is an excellent choice for architectural photography. Its near-zero geometric distortion allows for accurate representation of straight lines, which is crucial when photographing buildings and structures. This precision helps maintain the integrity of architectural designs, providing a true-to-life depiction of the subject.

What are the benefits of using a rangefinder coupled lens like the Biogon 21mm?

Using a rangefinder coupled lens, such as the Biogon 21mm, provides precise focusing, particularly in manual settings. This feature is beneficial for photographers who appreciate the tactile feedback and control that rangefinder systems offer. The lens's slim design also enhances handling, allowing for comfortable adjustments while composing shots.

What additional accessories or equipment work well with the Biogon 21mm lens?

For optimal use of the Biogon 21mm lens, photographers may consider the optional 21mm viewfinder for accurate composition. Additionally, using a suitable 46mm filter can enhance creativity and protect the lens. Filters such as polarizers or ND filters can help control reflections and manage exposure, enabling a broader range of photographic styles.

What types of photography are most compatible with the 21mm focal length?

The 21mm focal length is versatile and particularly effective for wide-angle photography applications. It excels in landscape and architectural photography while also being suitable for reportage work. This lens allows photographers to capture dramatic perspectives and dynamic compositions, making it ideal for storytelling through images.

How does the lens design contribute to its compactness and usability?

The compact and slim design of the Biogon 21mm f/2.8 lens enhances usability by making it lightweight and easy to handle. This design facilitates quick adjustments and a comfortable grip, which is especially beneficial during extended shooting sessions. The compact size also makes it an excellent travel companion, allowing photographers to carry it without adding significant bulk to their gear.
