Description

The Sigma Zoom 28-80mm F3.5-5.6 Macro (PK mount) is a versatile manual focus zoom lens crafted for photographers using PK-mount film cameras. Covering a focal range from 28mm at the wide end to 80mm at the telephoto end, it is ideal for a broad range of subjects—from landscapes and street scenes to portraits.

In addition to its standard zoom functionality, the lens features a dedicated macro mode that allows for close-up photography with a maximum reproduction ratio of about 1:4. This makes it a flexible choice for capturing detailed subjects without the need for a separate macro lens. Its variable aperture of f/3.5 to f/5.6 ensures good performance in bright conditions, while the robust optical design (featuring around 9 elements in 7 groups) helps minimize aberrations and deliver clear, sharp images.

With its compact, lightweight design and manual focus control, this Sigma zoom lens is well suited for photographers seeking an economical yet versatile option for both everyday shooting and macro applications on compatible film SLR cameras.
