The Biogon T 2.8/28 ZM delivers high detail accuracy and no distortion even at the close focusing limit and with the aperture wide open. Its optical design minimizes stray light or reflections, allowing for the integration of bright light sources into the image. The lens offers the largest angle of view that can still be used with the integrated viewfinder of the Zeiss Ikon. Additionally, a high-quality clip-on viewfinder for 25/28 mm is available. The Biogon T 2.8/28 ZM is well-suited not only for travel photography but also for group shots or interior architecture, especially in tight spaces or when minimal wide-angle distortion is desired.
