CFi lenses do not have electronics. CFE lenses (note the "E", for electronics
) do.
CFi ("i" for "improved") are CF lenses in a better barrel/mount.
CFE lenses are CFi lenses that have additional Databus contacts that tell the metering electronics in 200-series cameras what aperture they are and what aperture is set.
CFi/CFE lenses that have floating elements were also available in CF version.
With the exception of the IF version of the 40 mm Distagon, which didn't exist yet in the CF-period.
A CB version is a cheap version of a CFi lens. CB lenses already have the improvements that turned CF lenses into CFi lenses.
Mind you: these improvements are in the barrel only.
The CB 60 mm Distagon lens is the same design as the earlier and later 60 mm Distagon, and thus equally good.
The CB 80 mm Planar lens is a different design and slightly less good than the other Zeiss/Hasselblad 80 mm lenses.
The CB 160 mm Tessar lens was a new design. Yet - being a "B"udget lens - not on par with the nearest lenses in the CF and CFi/CFE lines.
There also was a CB 120 mm Makro-Planar lens, that was only available very briefly, and not everywhere. Consequently, a rare lens. It probably (haven't used one yet) is the same as the CF and CFE/CFi version.
