Mamiya 645 Sekor C Lens Set
Mamiya 645 Sekor C Lens Set
With roots in Medium Format portrait photography, the Mamiya 645 Sekor C lenses are now available for your next film project! These lenses possess the same optics as the donors of ARRI DNA Prime lenses.
With the included 0.7x Focal Reducer, you have access to our Mamiya’s entire image circle on an FF sensor, and the masterful Cine-Mod by Duclos Lenses makes it an ease to integrate into modern on-set workflows.
One of the standout characteristics of these lenses is their inherent edge focus falloff. Instead of maintaining sharpness from center to edge, these lenses present a gradual softening as you move toward the peripheries of the frame. This characteristic adds a vintage charm and a painterly quality, making the center of the frame pop with pronounced detail while the edges imbue the scene with a soft, nostalgic touch.
Mamiya 645 Sekor C lenses have the ability to cover motion pictures 65mm (such as Alexa 65) and are able to utilize the entire image circle on large format sensors (such as Alexa Mini LF, Sony Venice) with a x0.7 reducer and a bonus 1-stop effective exposure gain.
