The nitty-gritty details are: the Hasselblad 40 and 50 CF (shutter) FLE lenses
have a secondary focusing ring; the 50mm F (shutterless) FLE lens does not,
the floating elements thereby move automatically with normal focusing.  In
either case, the FLE lenses are said to perform better than their non-FLE
