This moderate wide-angle lens offers exciting, creative visual perspectives, but is also one of the easiest to control.
The ZEISS Biogon T* 2,8/25 ZM delivers high contrast across the entire image field and is virtually free of distortion at full apertures. With the aperture stopped down, detail is finely rendered with a pleasing three-dimensional quality. The lens is rangefinder-coupled for easy focusing and the optional 25/28 mm viewfinder is available for accurate image composition. The Biogon T* 2,8/25 ZM is a creative tool for scenic portraits, inspiring landscapes and expansive architectural photography.
