Hasselblad, Carl Zeiss T* Proxar 1m / 2m 51665 - 51667 Focusing loupe

PROXAR B60 (Bayonet 60) additional lenses for Hasselblad for CF, CFI and CFE lenses.
Versatility: They can be used alone or in combination with each other or with extension tubes and bellows to achieve even greater magnifications. They do not require exposure compensation.
Optical quality: The original Hasselblad Proxar lenses have been manufactured with the same quality and T* (Carl Zeiss) anti-reflective coating as the lenses, to ensure good optical performance.
Increased Magnification: Proxar lenses allow you to reduce the minimum focusing distance of the lens, allowing you to get closer to the subject and obtain greater magnification.
Proxars are measured in meters which indicates the distance the lens will focus when set to infinity.
Proxar 1 m: (number 51665) Corresponds to a lens of approximately +1 dioptre.
Proxar 2 m: (number 51667) Corresponds to a lens of approximately +0.5 diopters.
