1969 - Leica Summicron 50mm DR

這款產於1969年的Summicron 50mm F2 DR 鏡頭被廣泛認為是徠卡機械精準度的巔峰之作。這支鏡頭屬於令人夢寐以求的「235」序號範圍（序號：2356301至2358300），標誌著這款傳奇光學設計的最終篇章。它保存完好，如同全新盒裝一般，堪稱20世紀中期精湛工藝的縮影。 DR鏡頭以其卓越的近攝能力和嚴格的光學公差而聞名。

PRODUCED IN 1969, THE SUMMICRON 50MM F2 DUAL RANGE (DR) IS WIDELY REGARDED AS THE PINNACLE OF LEICA’S MECHANICAL PRECISION. THIS PARTICULAR UNIT BELONGS TO THE COVETED "235" SERIAL NUMBER RANGE (SN: 2,356,301 - 2,358,300), MARKING THE FINAL CHAPTER OF THIS LEGENDARY OPTICAL DESIGN. SURVIVING IN PRISTINE, "NEW IN BOX" CONDITION, IT REPRESENTS A TIME CAPSULE OF MID-CENTURY CRAFTSMANSHIP. THE DR IS RENOWNED FOR ITS EXTRAORDINARY CLOSE-FOCUS CAPABILITY AND THE RIGOROUS OPTICAL TOLERANCES THAT DEFINE THE GOLDEN AGE OF LEITZ WETZLAR.
