The 645 AFD lens system offers two ideally matched zoom lenses adding total 35mm format handling and flexibility to medium format quality. The AF 55-110 f/4.5 zoom covers the popular 35-70mm zoom range in 35, whereas the AF 105-210mm f/4.5 ULD is its perfect match covering a 68-130 equivalent range. They both offer a separate zoom and focus rings, plus the focus ring is a push-pull clutch to quickly switch between manual and autofocus. These lenses make the 645 AF system ideal for sports, travel and fast moving portraiture. Optical performance equals prime focal length lenses due to Mamiya's high quality computer aided design and manufacturing.

Applications cover a wide range of subjects including travel, wildlife, fashion, and landscape photography.

Equivalent to 34-68mm in 35mm format.
