Design and Features
This Biogon 2.8/21 lens bridges the gap between the Hologon T* 8/16 lens and the Biogon 2.8/28 lens for the Contax G lens range.
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. Examples include the photography of architecture and interiors. The relatively wide initial aperture of f/2.8 also allows available-light photography of interiors.
The almost symmetrical design of this lens also makes it suitable for the close-up range: its superb image quality, especially at infinity, is also evident in photographs of prototype and architectural models.
The Biogon 2.8/21 lens has been designed for use with the autofocus connection of the Contax G compact cameras.
