Lens OverviewContax 28mm f/2.8

The Contax 28mm f/2.8 is a manual focus prime lens built for the Contax/Yashica mount system, covering a full frame image circle. As a wide-angle prime with a 28mm focal length, it occupies a classic focal length well-suited to street photography, architecture, and environmental portraits. With a maximum aperture of f/2.8, it offers a respectably bright opening for a wide-angle lens, giving photographers the ability to work in lower light conditions and introduce some background separation at close focus distances.

The lens is manual focus only, meaning it suits photographers who prefer deliberate, tactile control over their focusing process — a workflow that pairs naturally with the considered pace of shooting on vintage SLR bodies. At 290g, it is a reasonably compact and manageable optic for its class. The 55mm filter thread provides compatibility with a standard range of filters.

Designed around the Contax/Yashica mount, it is a natural companion for original Contax SLR bodies, though its mount has also proven popular for adapted use on modern mirrorless systems via third-party adapters. Overall, this lens represents a purposeful wide-angle tool in the Contax/Yashica lens ecosystem, combining a fixed 28mm perspective with a bright f/2.8 aperture in a full frame-covering package.

DescriptionContax 28mm f/2.8

The Contax 28mm f/2.8 is a prime wide-angle lens designed for the Contax/Yashica mount SLR system, covering a full frame image circle. With a 28mm focal length and a maximum aperture of f/2.8, it delivers a broad perspective alongside enough light-gathering ability to handle a variety of shooting conditions. Focusing is entirely manual, putting direct control in the photographer's hands — ideal for those who enjoy a more deliberate shooting process.

The lens features a 55mm filter thread, making it straightforward to use with polarizing or neutral density filters from any standard filter brand. Weighing in at 290g, it balances well on SLR bodies without adding excessive bulk to a kit. There is no image stabilization, so a steady hand or stable shooting platform is advisable at slower shutter speeds.

This is a purposeful, fixed focal length tool built around the classic 28mm wide-angle perspective for Contax/Yashica system shooters.
