Sigma 28-80mm f/3.5-5.6 Zoom - Unknown Mount

This compact standard zoom lens was a popular choice for film SLR users, providing a versatile range from wide-angle to short telephoto. Often featuring a 'Macro' setting at the 80mm end, it allows for close-up photography with a decent reproduction ratio. Its lightweight, predominantly plastic construction makes it an unobtrusive travel companion for budget-conscious photographers. On the used market, these lenses are prone to 'Sigma finish' degradation, where the external coating can become tacky. The plastic mount and filter threads should be inspected for cracks or cross-threading. SDS verifies the autofocus speed and accuracy, ensures the macro switch engages correctly, and checks that the internal elements are clear of the fogging sometimes found in these older consumer zooms.
