Re: Olympus M Pro lenses

The Pro lenses feature constant apertures on the zooms and they and the primes are weather sealed.  The primes, according to most reports, are also sharp throughout their range and are sharp wide open.  These are the primary differences in the lenses.  The non-pro primes, by all accounts, are lighter and smaller, sharp, but generally lack weather-sealing and may be best when stopped down.  The non-pro zooms are also smaller & lighter, but again, lack weather sealing and there is usually a fall-off in sharpness at the longer FL (but not unacceptable except in some cases).
