2. Are wide-angle and/or tele attachments available from Carl Zeiss for Sony digital cameras and camcorders?
If yes, which, and for which cameras and camcorders?
Mutagon 0.6x T* and Tele 2x T* converters with 30mm thread diameter perfectly match the digital video camcorders that are equipped with ZEISS 3.3-33 mm Vario-Sonnar f/1.7 lens. These attachments are/were distributed through Sony.

3. Why are ZEISS lenses for Sony cameras produced in Japan?
Sony produces digital cameras of different types in extremely high numbers in several factories in Japan. The lenses for these cameras have to come from lens factories near the Sony camera manufacturing facilities to ensure reliable deliveries and minimize the economic risk of interrupted supplies.
ZEISS lenses for Sony digital cameras are developed by lens designers at the Carl Zeiss plant in Oberkochen, Germany. This includes all required quality assurance measures (test methods, test criteria, test devices, test procedures, lens performance target values, etc.) The lenses are then made in a lens production facility jointly chosen by Sony and Carl Zeiss. Quality assurance specialists from the Carl Zeiss plant in Oberkochen implement the ZEISS quality assurance system in the chosen facility. Many ZEISS optic measuring systems are installed. Carl Zeiss audits the lens production areas on a regular basis.
All these measures ensure that ZEISS lenses in Sony digital cameras meet the expectations demanding users associate with ZEISS lenses.

4. Vario-Tessar or Vario-Sonnar: which one is better?
The difference between these two lens types does not lie in their image quality. Vario-Tessar allows smaller lens sizes because the attainable zoom factors, e.g. 3x, 5x, are smaller and the lens speed is lower, e.g. 1:3.5. Vario-Sonnar is bigger and permits higher zoom factors, e.g. 6x, 12x and more – and higher lens speeds, e.g. 1:2.0. The image quality of the two types meets the high quality standards of Carl Zeiss.
