Phase One Announces 40mm-80mm f/4–5.6 Lens for Its Digital 645 System

When it comes to medium format photography, prime lenses are the norm. The size, weight and quality of construction of lenses are all areas of constraint for medium format over DSLRs or mirrorless, and so zoom lenses are more of a rarity.

However, there are always impressive exceptions to the rule, which is exactly what Phase One has done with its second-ever zoom lens for the 645 digital medium format system.
