Description — Contax 28mm f/2.8 Zeiss Biogon T*
The Contax 28mm f/2.8 Zeiss Biogon T* is a prime wide-angle lens designed exclusively for the Contax G rangefinder camera system. Operating at a fixed 28mm focal length, it falls squarely in the wide-angle range and covers a full-frame image circle. The maximum aperture of f/2.8 allows for capable performance in varied lighting conditions, while the lens's autofocus support adds a level of convenience that is far from universal in rangefinder-mount optics.
Weighing just 200g, it is a genuinely compact addition to any Contax G kit. The 46mm filter thread keeps accessory costs reasonable and sourcing straightforward. There is no image stabilization on this lens, so steady technique or adequate shutter speed is important when shooting handheld.
For photographers already invested in the Contax G system who are looking for a dedicated wide-angle prime with autofocus, this lens covers all the core specifications needed.
