Plastic has significant advantages in the construction of a lens, as it serves to cushion shocks. An all-metal lens transmits any shock to the one malleable element in the lens, the glass, which then breaks. Plastic, on the other hand, absorbs a lot of the shock. I have (by accident, guys!) tossed all-metal and metal-and-plastic lenses across the room. The all-metal boys died. The metal-and-plastic ones lived. Given the price charged for Leica lenses, I'm glad the manufacturer is concerned over in-use longevity. Makes me thing the Mavens of Solms DO care about us!
