Explore wide perspectives with the Zeiss Biogon T* 21mm f/2.8 ZM in silver. This fast, super-wide lens delivers extreme resolving power even when shot at its maximum aperture. It provides consistent contrast across the frame while maintaining excellent control of flare, ghosting and distortion.

Optical performance

The Biogon T* 2,8/21 ZM performs strongly across a variety of shooting conditions. It resolves detail exceptionally well, including when you shoot wide open. In addition, it shows virtually no distortion and offers superb contrast rendition across the entire image area. The T* coating helps control flare and ghosting for cleaner images in challenging light.

Design and handling

The lens features a slim design that is easy to grip and focus. It is rangefinder-coupled, which enables straightforward and precise focusing on compatible cameras. Because the lens uses a standard 46 mm filter thread, you can interchange filters between many ZM-series lenses that share the same diameter.

Its super-wide field of view and strong image quality make it suitable for any situation where wide-angle coverage and fine detail are important.

Frequently asked questions

Question: Is this lens rangefinder-coupled and easy to focus on a rangefinder camera?
Answer: Yes. The Biogon T* 21mm f/2.8 ZM is rangefinder-coupled, which makes focusing straightforward on compatible rangefinder bodies.

Question: Do I need a separate viewfinder to compose at 21 mm?
Answer: An optional 21 mm viewfinder is available for accurate composition when shooting at this focal length. If your camera does not offer a built-in 21 mm viewfinder, using the optional viewfinder will help you frame precisely.

Question: What filter size does this lens use and can I share filters with other ZM lenses?
