Description — Mamiya 105-210mm f/4.5 ULD
The Mamiya 645 AF 105-210mm f/4.5 is a telephoto zoom lens purpose-built for the Mamiya 645 medium format system. It spans a 105mm to 210mm focal length range, making it a go-to option for photographers who need telephoto reach without swapping glass in the field. The lens holds a constant f/4.5 maximum aperture throughout its zoom range, so exposure behavior stays predictable from one end to the other.
Both autofocus and manual focus are supported, offering flexibility depending on the shooting situation. A 77mm filter thread opens up compatibility with a broad selection of screw-in filters, and the lens mounts natively via the Mamiya 645 mount. At 1200g, this is a serious, substantial optic reflecting the demands of medium format image-making.
There is no image stabilization, so a steady hand or support system is recommended, particularly toward the 210mm end of the range.
