The result is the possibility of ideal lens designs, which Mamiya's computer-aided optical R&D department crafts with the utmost pride and unsurpassed precision of any medium format system. The extreme accuracy of rangefinder focusing and lack of shutter or mirror vibration also contributes to razor sharp results not obtainable with SLR lenses.
