A short resume,
C- Synchro-Compur shutter, developed for the 500 series but in B setting, also operate with 2000FC and 200F focal plane bodies, being the exception to that, the 202FA.
These lenses are satin chrome, the black ones became available in the 70`s.
C T*- These optics are the same than the older C`s, the diference is the 6 layers coat to reduce flare and improve contrast.
Earlier models are satin chrome, later are black.
CF- C`s redesign, different shutter type (Prontor), handling improved and an F setting was added for operation with focal plane shutter bodies.
Self-timer removed, shutter speed and aperture rings operations are independent, cross-coupling button to move both and retain the EV setting.
CB- Lower cost alternative to the CF`s.
F- Developed for 2000FC series, similar to CF`s but without shutters, therefore, shutter speed ring removed.
Faster and closer focus than the CF`s.
FE- Developed for the 200F series, similar to F lenses but with a 4 pins electronic databus connector.
Can be used with 2000FC cameras but without taking advantage of the databus of the lenses.
CFE- CF`s with the databus of the FE`s, double blue lines (common to FE`s) and focus limiter knobs in the front.
