Thank Rick, a prime lens worthy of the UM Pro, now if only I could win the Lottery
Unlike so called "faster" Primes that are only sharp stoped down, Leica lenses can be used from their max f/stop down, and are in many cases sharper at the wider f/stops. So while T2.6 to T3 seems "slow" they are quite useable at T2.6 or T3 etc.
