Carl Zeiss Jena Sonnar 2.8/180 for Pentacon Six.

Vintage Leica lenses show great performance on Fujifilm X-Pro2. So, I used Summicron 5cm F2 and Elmar 9cm F4 at Osaka Motor Show 2017.

Onomichi, Japan.
X-Pro2, Summicron 5cm F2 LTM and Fujifim M mount adapter

Summicron 5cm F2 LTM was made in 1950s. Also, Modern Fujinon XF 50mm F2R WR has same spec. It is very interesting in the difference between these two lenses.
