Zeiss Touit: Naming, Materials, Production, Service
The Zeiss Touit lenses for Sony NEX and Fuji X are reviewed in depth in Guide to Mirrorless.
May 2013 Q&A from Carl Zeiss Inc.
Where does the name Touit come from?
In the future, ZEISS lenses in a series will have a family name that will convey a common identity. For this reason, we have decided to derive these family names from the Latin names for birds, which we find appropriate because birds generally have excellent eyesight, take in extraordinary perspectives, are flexible and enjoy life.
Furthermore, the names sound nice and are generally compatible in many different languages and cultures. The name Touit – like the new ZEISS lenses for mirrorless system cameras – stands for good vision, agility, mobility and versatility. The name is derived from a small species of Brazilian parrot.
How do you pronounce Touit?
Touit is pronounced like the English words "do it." [tʊɪt]
Why don't these lenses have the typical ZEISS names (Distagon, Planar)?
Will the proven names (Distagon, Planar, Sonnar) be discontinued in the future?
The names of the optical concepts (Distagon, Planar, etc.) used until now in the product names, as well as the T* designation for the antireflective coating stand for properties of the lenses, but are not actually the name. Furthermore, they are engraved on the front ring of the lenses.

What are the lenses made of?
The mirrorless system cameras are lighter and more compact than SLR cameras. With our new lenses for this camera system we are continue the development of our high quality lens concept while simultaneously aiming at a relatively light-weight design. For the mechanical components we looked for the best compromise between the quality of the material and the product's total weight. For this reason, we decided to use a combination of materials. For parts that do not require metal for accuracy, solidity or durability, we have incorporated lighter materials such as plastic.
Why is the lens shade on the Touit lenses made of plastic and not metal?
In addition to a more economical manufacturing process, a plastic lens shade is also lighter than a metal lens shade. In the market of lenses for mirrorless system cameras, every gram that a photographer does not have to carry counts. Therefore, the lens shades on ZEISS Touit lenses are made of a high-quality, light and robust plastic.
Where are the lenses made?
For the manufacture of ZEISS lenses, we use a global production network of trusted partners in the optical industry that has been built up over many years. Touit lenses are made in Japan.
What exactly does ZEISS mean with "a global production network of trusted partners in th optical industry that has been built up over many years." ?
In times of globalization, it is common to outsource production to partners who in terms of production quality, reliability and capacities are best suited to manufacture a certain product. From the beginning, one of our areas of expertise has been to shape production processes to ensure ZEISS quality – regardless of the site.
We work with a network of partners: certain products can therefore be manufactured in different locations. Regardless of where a product is made, our know-how and technology for production and quality inspection always ensure that a ZEISS lens is created that meets our stringent demands on quality and performance.
Will the lenses be manufactured at Cosina in Japan?
We manufacture our lenses with the help of a global network of trusted partners that has been built up over the years. Please understand that we cannot provide any details on the network or the structure of our production process.
What is the difference to the ZEISS lenses sold by Sony?
High-performance ZEISS lenses have been available for the Sony Alpha since 2005 and for the NEX system developed jointly by ZEISS and Sony since 2011. The lenses are manufactured under the leadership of Sony. Sony ensures compliance with the specified ZEISS standards of quality. Sales and service are provided by Sony only. The ZEISS Touit lenses for the Sony NEX system and Fujifilm X system were developed exclusively by ZEISS. The lenses are manufactured under the direct control of ZEISS. Sales and service are provided by ZEISS.
Future: focal lengths, mounts
What about MFT (Micro 4/3)? Are the lenses also planned for MFT?
We would also like to offer lenses for demanding users in the mirrorless system cameras segment. The largest and most powerful sensors (APS-C format) in compact system cameras at the moment are currently found in the Fujifilm X and Sony NEX system cameras. Therefore, we are focusing on these systems with our Touit lenses.
In order to reach the best compromise between lens size, weight and imaging performance for smaller sensors, e.g. the Micro 4/3, other optical and mechanical designs are sometimes more suitable than for APS-C.
Lenses for the Micro 4/3 mount are technically possible, but nothing is planned yet.
Are additional focal lengths planned? If yes, which?
As already announced at the 2012 photokina, the next lens will be the Touit 2.8/50 Macro. Additional focal lengths will follow, Right now, we do not want to divulge any further details.
Will there be a zoom lens?
We are starting the family with fixed focal lengths. Zoom lenses are an option that is currently being evaluated.
When will the new lenses be available?
The Touit 2.8/12 and the Touit 1.8/32 will be in stores from June 2013. The Touit 2.8/50 Macro is expected in stores by the end of 2013.
What can I do to get a Touit lens as soon as possible? Can I sign up to buy one in advance?
You can register on the ZEISS website (www.zeiss.com/photo) from May 2013. As soon as the lenses are available, all registered customers will be notified via email.
When will the Touit 2.8/50 Macro be available?
The Touit 2.8/50 Macro will be in stores at the end of 2013.
