Product Overview
The Carl Zeiss Biogon T* 2.8/21 is an ultra-wide angle prime lens designed for the Contax G compact cameras. With its large field angle across the diagonal, this lens is suitable for photography where not only a dynamic perspective, but also high image quality and minimum distortion are required at the same time. Ideal for architectural and interiors photography. The relatively wide initial aperture of f/2.8 also allows available-lgiht photography of interiors.
