Renaming of Schneider-Kreuznach lenses

In order to make information more accessible, Schneider-Kreuznach has decided to restructure the lens range and rename the lenses accordingly. Following existing names, all product families will be named after gemstones.

Your benefit

  • You will be able to find a lens with specific features faster.
  • The naming is consistent across all documents, data and on the lens.
  • All features are transparent through the "descriptive name”. Our example below shows the current Xenoplan-M 2.0/28.
