This is the worldwide first published image of the new Zeiss Loxia 50mm f/2.0 Planar E-mount Full Frame lens. Like I told you before Zeiss will soon announce a new line for Full Frame E-mount which also includes the Zeiss 35mm f/2.0 Biogon. These lenses are just like the Touit for the APS-C E-mount system: Made by Zeiss itself (not Zeiss branded Sony the Zeiss 55mm f/1.8 FE). But the Loxia lenses will be manual focusing and with electronic aperture control. And unlike current Sony FE lenses the Loxia comes with a handy physical aperture ring.
Planar® with 6 lens elements in 4 groups
Focal length 50 mm
Aperture range f/2.0–f/22
Elements/groups 6/4
Focusing range m/ft 0.45–∞/1.48–∞
Field angle* (diag./horiz./vert.) 46.78°/39.38°/26.70°
Coverage** mm/inch 255.1 x 168.3/10.04 x 6.63
结构好简单，6片4组。就是不知道这镜头的卖点在哪儿？毕竟FE55已经表现的很好了，而且估计售价也比FE55高。不过相对来说还是更期待索蔡的FE1635~
