SERIAL NO. 410308, 1937
Leitz Wetzlar rare original TROPEN Summar 1:2/5 cm lens. In between the 400.000 serial number range of the Leica lenses, very few series of Summar lenses indicate "Tropen" in the factory records. It is meant that lenses are especially suitable for tropical environments. There are two key-features of the tropical Summar lenses, what concerns their technical standards: First of all, the lenses contain a compound front-element, balsamized of two elements. So in fact, the tropical Summar lenses are of a seven-element design instead of the regular six-element. Second, the tropical Summar lenses have a ball and groove design in the collapsible barrel, similar to the later Summitar lenses. Tropical Summar lenses are extremely rare. Compare VIDOM Nr. 89 (Leica Historica, Germany 2005), page 29. This lens comes with both lens caps and it has been authenticated by Lars Netopil.
此“TROPEN”Summar,極為罕有且不為人知,是專門為適應熱帶地區的環境而設計。此鏡頭與量產版Summar的最大分別為在鏡頭前端增加多一枚鏡片,為七組鏡片設計﹔另外鏡筒的伸縮部分有明顯的凹槽,此特徵只見於Summitar鏡頭中。有關資料可參閱VIDOM Nr. 89 (Leica Historica, Germany 2005), p 29。此鏡連同前後蓋。拍品經由Lars Netopil鑑定。
