808的鏡頭結構可能要再求證一下
tessar鏡頭結構從來就只有4片
另外它的光圈設計從未大於f2.8(808好像是f2.4)
所以他應該不是tessar鏡頭
不過Nokia或Carl Zeiss似乎也未曾說明他是屬於何種結構......

這個跟tessar 結構完全沒關係
這是手機鏡頭的一種架構而已 由4P去延伸的
因為有極短的後焦 優化後就會長這樣啦
所有手機廠4P 5P都長一樣
Tessar 的 WIKI 上有寫 808 屬 Vario-Tessar
http://en.wikipedia.org/wiki/Tessar
Vario-Tessar
The Vario-Tessar has only the name "Tessar" in common with the original Tessar.
It is sometimes a 5-elements-in-1-group, aperture-less all-aspherical lens,
as in the Nokia 808 Pureview camera. The Vario-Tessar name has been used by
Zeiss for various zoom lenses including that of the digital still cameras Sony
Cyber-shot DSC-P100[5], DSC-P200 and DSC-w330.
