The 645 Series offers two ideally matched zoom lenses adding total 35mm format handling and flexibility to medium format quality. The 55-110 f/4.5 zoom covers the popular 35-70mm zoom range in 35, whereas the 105-210mm f/4.5 ULD is its perfect match covering a 65-130mm equivalent range. They both offer a separate zoom and focus rings. These lenses make the 645 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.
