Sigma 35-200mm f/4-5.6 Zoom - Unknown Mount

The Sigma 35-200mm is a high-ratio 'superzoom' lens for its time, designed to provide a one-lens solution covering everything from wide-angle to telephoto. Its complex optical design allowed film photographers to travel light without switching lenses. It typically utilizes a one-touch zoom and focus ring, allowing for quick adjustments in changing environments. Due to the complex internal movements required for such a wide zoom range, mechanical wear is a primary concern. SDS checks that the zoom action is smooth across the entire range without binding. We also inspect for centring issues or softness that can occur if internal elements have shifted. The aperture is tested for responsiveness, and the lens is checked for the presence of internal moisture or fungal growth.
