Sigma 35-135mm f/3.5-4.5 Zoom - Unknown Mount

The Sigma 35-135mm f/3.5-4.5 is a versatile manual focus zoom lens from the film era, covering a broad range from wide-angle to moderate telephoto. It is useful for general travel and street photography, offering a faster maximum aperture than many modern kit zooms at the wider end. The push-pull zoom design allows for quick focal length adjustments, while the multi-coated optics help to reduce flare and maintain contrast. When buying this lens used, check the push-pull zoom mechanism for excessive slack or 'zoom creep', as these older designs can become loose over time. SDS technicians inspect the internal elements for haze and fungus, which can occur in vintage Sigma lenses. Ensure the aperture blades are snappy and free from oil, and check the mount for any significant wear that might affect the fit to the camera body.
