Sigma 35-70mm f/2.8-4 Zoom - Unknown Mount

The Sigma 35-70mm f/2.8-4 Zoom is a standard zoom lens that offers a fast f/2.8 aperture at the wide-angle end, making it more capable in low light than standard kit lenses. Its compact size and versatile focal range make it a strong candidate for general-purpose film photography. The lens typically features a multi-coated glass construction to help mitigate flare and improve colour reproduction when shooting in backlit conditions. On the used market, ensure the variable aperture mechanism is functioning correctly and that the aperture blades are free from oil contamination. SDS checks the mechanical rings for gritty movement, which can indicate sand or dirt ingress. As these lenses often saw heavy use as primary lenses, check the front element for cleaning marks or scratches that might affect image contrast and sharpness.
