Zeiss Touit 12mm f/2.8 Distagon — Autofocus Ultra Wide Angle for Sony NEX or Fuji X

Zeiss Touit 12mm f/2.8 Distagon

The Zeiss Touit 12mm f/2.8 Distagon will be available in Sony NEX or Fuji X mount starting in June.

As far as the eye can see—

With an angle of view of 99 degrees, the Touit 2.8/12 wide-angle lens will soon become a firm favourite, particularly for landscapes and architectural photography.

Its unique T* multicoating guarantees maximum transmission and outstanding absorption of extraneous light. The result: breathtaking image quality from edge to edge and corner to corner of the entire image field.

What’s more, all moving parts of the Touit 2.8/12, conceived specifically for Sony NEX and Fujifilm X Series cameras, are engineered for extreme precision and a long working life. And finally, its strong and rigid metal bayonet mount makes it an absolutely dependable companion for many years to come.

Key features:

  • Almost circular aperture with 9 blades, for especially harmonious rendition of highlights outside of the focal plane.
  • Lens hood seamlessly integrated into the overall design.
  • Metal bayonet mount guarantees extreme rigidity and rubberized setting rings enable precise manual control when needed.
  • Aspherical lens design ensures consistent imaging performance throughout the entire focusing range as well as sharpness to the periphery of the image.
  • Latest floating element design principles. Optical aberration effects in ZEISS lenses are reduced to a minimum throughout their entire focusing range, achieved by variation of the axial distance between individual lens elements or groups. This adjustment of the lens-to-lens distance is coupled to the distance setting to ensure correct compensation at all times. The mechanical construction of these lenses is extremely complex and they must be assembled with utmost precision.
  • Various, elaborate techniques to reduce unwanted stray light.

See the notes on lens corrections for Zeiss Touit lenses on Sony NEX / Fuji X.

In a break with tradition, MTF charts are not provided with the Zeiss Touit line, unfortunate in my view.

Optical design

Note the emphasis on digital friendly ray angle. Chief ray angle is serious issue with rangefinder lenses adapted to Sony NEX or Fuji X.

With two aspheric elements and three elements made of special glass types along with floating element, this ought to be a very high performer.
