ZEISS PLANAR T* FE 50MM F1.4 ZA
Classic focal length meets space-age technology! Crazy resolution and contrast for incredible IQ, fast aperture and 11 rounded blades for low light shooting and gorgeous bokeh, the top tier auto and manual focus implementation for any shooting conditions, weather sealing in a robust body and all important controls... they all there. If there was one lens to own that can hold it's own in any occasion this would be it.
