Summicron-M 50mm f/2（1969–2023）
別名 "Summicron 50 v3", "Summicron 50 v4", "Summicron 50 v5"
第三代 Summicron（v3，1969 年）確立了現代標準：6 片 4 組設計，緊湊、精密、從最大光圈起即表現卓越。此後的 v4 和 v5 在此基礎上持續精進，v5 針對高解析度數碼感光元件優化，同時保留了 Summicron 標誌性的色調特質。對新手而言：50mm Summicron 是徠卡鏡頭體系的基準——不是最快的，也不是最銳的，但它以最自然、最完整的方式還原場景，是徠卡攝影中「標準」的定義。

版本與塗裝
Second version of the modern 50 Cron: a compact collapsible-style barrel replaced by a proper focusing tab and standard 39mm filter thread. The starting point for most collectors of the modern series.
Leica integrated a built-in telescoping lens hood, removing the need to carry a separate hood. Beloved for convenience; slightly longer than V2 when hood is extended.
Final current version: the built-in hood became a removable screw-in hood and the focus tab came back. The most refined version optically and the easiest to find new or lightly used.
