1956 - Nikon Micro-Nikkor 50mm F3.5 L39 for Leica L39

1956年發表的Micro-Nikkor 50mm F3.5鏡頭是光學精準度的里程碑。這款鏡頭誕生於徠卡L39螺口卡口的黃金時代，專為微距攝影而設計，在當時提供了無與倫比的解​​析度。此款鏡頭為徠卡L39卡口限量生產。早期生產的鏡頭在名稱環上帶有獨特的紅色“C”字標記，而後期生產的鏡頭則去除了這個標記。對焦環上特有的黃銅色澤和清晰的雕刻反映了攝影與科學精確性相結合的機械時代。

RELEASED IN 1956, THE MICRO-NIKKOR 50MM F3.5 IS A MILESTONE IN OPTICAL PRECISION. DESIGNED DURING THE GOLDEN AGE OF THE LEICA L39 SCREW MOUNT, THIS LENS WAS ENGINEERED SPECIFICALLY FOR MICRO-REPRODUCTION, OFFERING UNPARALLELED RESOLUTION AT THE TIME. THIS PARTICULAR VERSION WAS PRODUCED IN LIMITED QUANTITIES FOR LEICA L39 MOUNT. THE EARLY PRODUCTION UNITS FEATURE THE DISTINCTIVE RED "C" ON THE NAME RING, WHILE LATER UNITS REMOVED THIS MARKING. THE CHARACTERISTIC BRASSING ON THE FOCUSING RING AND THE SHARP ENGRAVINGS REFLECT A MECHANICAL ERA WHERE PHOTOGRAPHY MET SCIENTIFIC EXACTNESS.
