Sean Reid's review of the 75mm Summarit is out. Besides the fact that the Summarit performs quite excellently, inexpensive CV 75 gave the two Leica contenders (Summicron in addition to the Summarit) a run for the money.
But go see yourself, again a review worth reading from Sean.
One more lens omparison, which makes me think which Leica lens is still undisputed king of its focal length. Maybe only the 50lux asph?
