Sigma 28-70mm f/2.8 Zoom Lens — Canon FD Mount

Canon FD glass gets a lot of attention for good reason — the mount produced some of the sharpest, most characterful lenses of the manual focus era. But while everyone chases the Canon brand names, third-party manufacturers like Sigma were building FD-mount glass that competed directly with the first-party options at a fraction of the price. The Sigma 28-70mm f/2.8 is exactly that kind of lens. The f/2.8 maximum aperture is the headline. It holds constant across the entire 28–70mm zoom range — which means you’re not losing light as you zoom in, and you’re getting the same shallow depth of field and low-light capability at 70mm that you have at 28mm. That’s not a given at this focal length range. It’s a feature you pay for, and it shows in the results. At 28mm you’ve got a wide view that works for street, architecture, environmental portraits, and group shots. At 70mm you’re in classic portrait territory — flattering compression, smooth background separation, and the kind of subject isolation that makes a frame feel intentional. Everything in between is practical, versatile, and fast. This lens works on any Canon FD or FL mount body — the AE-1, A-1, F-1, AE-1 Program, T90, and more. It also adapts to mirrorless systems with an FD adapter, making it a strong pick for Sony, Fuji, and Micro Four Thirds shooters who want fast manual focus glass with real character. This Sigma 28-70mm f/2.8 FD is in excellent condition — glass is clean, aperture blades are snappy, zoom and focus rings are smooth, and the lens performs exactly as it should.
