Optical performance and rendering

The Biogon T* 25mm f/2.8 ZM achieves consistently high contrast across the full image field. As a result, you get clear tonal separation and strong micro-contrast in most shooting situations. Moreover, the lens exhibits virtually no distortion at full apertures, which helps preserve straight lines and architectural geometry without heavy correction in post.

Stop down the aperture and the lens refines detail reproduction, offering a depth and three-dimensional rendering that benefits portrait and landscape work alike. This change in rendering when stopping down provides photographers with creative control over image character and depth.

Handling and composition

The lens is rangefinder-coupled, which supports precise manual focusing and a direct shooting experience. For photographers who prefer optical framing aids, an optional 25/28 mm viewfinder is available to ensure accurate composition when using cameras that require external finders.

Ideal use cases

• Scenic portraits that take advantage of the lens’s perspective and three-dimensional rendering.
• Inspiring landscapes where wide coverage and high contrast improve clarity and impact.
• Expansive architectural photography that benefits from low distortion at wider apertures.

Purchase notes

Please note that the lenshood is sold separately. If you need a viewfinder for composition, the optional 25/28 mm viewfinder can be obtained to match this focal length.
