Design and Features
The hallmark of Biogon T* wide-angle lenses is excellent image quality combined with a wide initial aperture and a wide field angle. This type of lens is not suitable for use with SLR cameras, as its design requires a short back focal distance (distance from the last lens vertex to the film plane). An outstanding Biogon T* lens has been developed for the Contax G compact cameras, incorporating the knowledge gained so far in the design of this type of lens.
The focal length f = 28 mm of this lens makes it ideal for photography where a dynamic perspective is required. The lens is also suitable for the close-range photography of interiors, as its constantly high image quality and excellent distortion correction extend up to the close range. The Biogon T* 2.8/21 lens has been designed for use with the autofocus connection of the Contax G compact cameras.
