Just noticed on my shutter speed dial of my 50mm CF, that there is a green letter F and a green protruding dot on the ring. What are they for?

What's the green F and green dot for?

I believe this is for use with a 200 series camera utilizing the focal plane shutter on those bodies.
F mode for CF/CFE/CFi lenses
The "F" mode indicated by the green dot means the shutter of the lens is always open.
In that position the lens functions like an F or FE lens for 2000 bodies or 200 series bodies with a focal plane shutter.
F or FE lenses do not have a shutter and are generally 1 stop faster than lenses with a leaf shutter.
The first Hasselblad cameras, often called 1600F, were cameras with a focal plane shutter.
In 1957 Hasselblad presented the 500C camera that did not have a shutter.
For the 500C Hasselblad offered a new series of lenses with leaf shutters.
Twenty years later a new series of bodies with electronically controlled focal plane shutters were made available.
These bodies were named after their fastest shutter speed: 1/2000 second.
In the early nineties a new series of bodies with focal plane shutter and light metering were introduced.
The 200 series eventually had 4 different bodies: 205TCC, 205FCC, 203FE and 202FA.
