• Optics for digital photography
  picture sharpness, format, limits of image sensors, new digital lens series from SCHNEIDER-KREUZNACH
  

• The image quality of lenses for digital photography
  transfer chain in digital photography, image sharpness and contrast, geometrically accurate reproduction, brightness distribution over the image, good light transmission by the lens, a minimum of scattered light (stray light), absence of color fringes
  

• Hydrophobic MRC-coating
  dust- and water-repellant system of coatings, easy cleaning of the optical surfaces, significantly higher resistance to mechanical scratches, assembly and effect
