C Lense
Since the introduction of the Hasselblad 500C in 1957, all the Carl Zeiss Compur shutter lenses made for Hasselblad were distinguished by their unique lens barrel design with interlocked aperture and shutter-speed rings, automatic depth-of-field scales, M and X flash synchronization (sync), and the built-in self-timer. Although C lenses can be mounted on focal plane shutter cameras, use of this combination for photography is not recommended. The shutters in these old lenses are usually no longer in good enough operating condition to meet the critical synchronization requirements that are necessary between the shutter in the lens and the focal-plane curtain in the camera.

CF Lenses
At the end of 1982, all C lenses from 30mm to 500mm, including the 38mm Biogon on the Superwide, were replaced by the CF line of Carl Zeiss shutter lenses. Their completely redesigned lens barrel with a new shutter includes features that Hasselblad and Carl Zeiss felt were most important to the Hasselblad photographer while at the same time leaving out some features that were seldom used. One of them was the self-timer. All this was done to improve the operation and to standardize the lenses somewhat more with the F non-shutter types while improving shutter performance.
Aperture and shutter-speed rings are no longer interlocked on CF lenses but can be locked together easily when desired. The manual stop down control is more convenient and the M sync setting has been eliminated, All lenses are attached to the camera and removed in the same fashion.
The shutters in CF lenses are made in three different diameters (18, 22, and 24mm) and each CF lens is equipped with the shutter that is most efficient for that particular lens. Their larger diameter with fewer cutouts around the leaf shutter makes the CF lenses exceptionally strong. This is especially noticeable on the heavier and longer types – Distagon 40mm and 50mm, the 350mm and 500mm telephoto lenses. The lens barrel and all components that hold lens elements, and are important to reliability and operation of the lens as well as for maintaining its quality, are machined from aluminum alloy or other metals. Plastic is used only for small components such as the stop-down lever, interlock levers, and so on.
The CF shutters are easily accessible and easy to repair. With three exceptions – the 40mm Distagon, the 120mm Macro Planar, and the 500mm Tele-Apotessar – the lenses differ in operating controls only, not in lens design.

CFi Lenses
The CFi lenses are optically identical to the CF types. The front diameter for use of filters and lens shades also has been maintained but the front ring is made from a solid black acrylic material that is practically indestructible and will never show any signs of wear and usage. The rear bayonet ring is a single piece of specially treated metal. Other changes are in the operating control and the design of the lens barrel. The interior behind the lens elements has been opened up to reduce possible light reflections on the interior wall. The locking between the aperture and shutter-speed ring and the operation of the manual stop down control have been made more positive and convenient. Focusing is easier and the flash connector is equipped with a cable locking device. CFi lenses also have a newly designed mainspring made from Nivarox, which is expected to perform reliably three times longer.
CF and CFi lenses have a F setting on the shutter-speed ring that allows their use on all focal plane shutter in the camera. The lens shutter also can be used for making the exposure in these cameras except for the 202FA model.

CFE Lenses
Lenses designated CFE are identical to CFi types but also have electronic connections to the light metering system built into some hasselblad camera models.

CB lenses
In the Limited line of CB lenses, Carl Ziess eliminated some features and function that many photographers do not need or use. This allowed reducing the cost somewhat without reducing the quality or reliability. One main difference is in the elimination of the F setting on the shutter-speed ring. CB lenses can be used on focal plane shutter cameras (except for the 202FA), but the exposure must be made with the shutter in the kens. CB lenses do not have the Nivarox mainspring but the same mainspring that has been used in CF lenses for many years.
Some lens designs (for example, the 60mm) are identical to the CFi type, others are new and different. Although CB lenses were designed and made to the same standards as the others types, most hasselblad users selected the CFi or CFE types. As a result, CB lenses have been discontinued.
