� 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 � 70 mm zoom range in 35, whereas the 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. These lenses make the 645 system ideal for sports, travel and fast moving portraiture.
