Looks like we need to practice patience for this much sought after lens. Availability of the APO-Summicron-M 50mm f/2.0 ASPH is delayed with no estimate from Leica on a delivery date.
From Leica : “As you are aware, Leica is dedicated to producing products that exhibit mastery in optics and mechanics, high- quality design and outstanding craftsmanship. Our engineers and designers constantly strive to meet the challenges set by those with the highest expectations and only after extensive testing and quality control exercises is a product deemed worthy to enter the marketplace. Due to the extraordinary technical requirements of the new APO Summicron – M 50mm/f2 ASPH lens, the manufacturing processes are complex and sensitive. We regret to inform you that the first shipment of the APO Summicron-M 50mm/f2.0 ASPH has been delayed due to technical reasons as we actively work to determine a stable production process for this new lens.”
