The Zeiss 25mm f/2.0 Distagon T* ZE and ZF.2 Lenses were announced yesterday.
I had the pleasure of using the Zeiss 25mm f/2.0 Distagon T* ZE Lens at PhotoPlus Expo in New York City yesterday.
The build quality of this lens is on par with the other Zeiss ZE lenses - which is to say that this is an incredibly-well built lens. Zeiss ZF.2 Nikon mount lenses are built similarly to the ZE Canon mount counterparts. This lens is rather small (does not take up much space in a bag), but solid feeling (if you fill all the space in your bag with similar Zeiss lenses, your back may regret you having done so).
Image quality from this lens is expected to be on the level of the great Zeiss 21mm f/2.8 ZE Distagon Lens' image quality.
