Phrase: Sonnar lens design | Statement: [Carl Zeiss optics, associatedWith, Sonnar lens design]

Target entity: Sonnar lens design
Context triple: [Carl Zeiss optics, associatedWith, Sonnar lens design]

• A. Maksutov–Cassegrain telescope design
  The Maksutov–Cassegrain telescope design is a compact catadioptric optical system that uses a spherical primary mirror and a meniscus corrector lens to provide long focal lengths with well-corrected, high-contrast images in a relatively short tube.
• B. Dall–Kirkham telescope design
  The Dall–Kirkham telescope design is a type of reflecting telescope that uses an elliptical primary mirror and a spherical secondary mirror to provide good on-axis image quality with relatively simple, easy-to-manufacture optics.
• C. Schmidt–Cassegrain telescope design
  The Schmidt–Cassegrain telescope design is a compact catadioptric optical system that combines a spherical primary mirror with a Schmidt corrector plate to provide long focal lengths in a short, portable tube widely used in amateur and professional astronomy.
• D. Cassegrain telescope design
  The Cassegrain telescope design is a reflecting telescope configuration that uses a combination of a primary concave mirror and a secondary convex mirror to fold the optical path and produce a compact instrument with a long effective focal length.
• E. Carl Zeiss optics
  Carl Zeiss optics refers to the high-quality camera lens technology developed by the German manufacturer Carl Zeiss, renowned for its precision and use in premium imaging devices.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
