Schneider Kreuznach, durst Componon 5.6/360mm | Enlarger lens

Very large objectives. This is a magnification (or printing) objective renowned for its high quality and sharpness.
Optical specifications
• 1:5.6 (Maximum Aperture): Indicates the maximum aperture.
• 360 (Focal Length): 360 mm. This is a very long focal length for a magnification lens, making it suitable for enlarging very large negative formats (such as 8x10 inches or larger) or for long-distance projections.
Serial Number: 11510193.
• Additional brand: The orange inscription 'Durst' in the center suggests that this lens was produced or optimized for use on a Durst photographic enlarger, one of the leading companies in the professional enlarger sector.
Use: Its main purpose is not to take photos, but to project and focus an image of a negative onto light-sensitive paper inside a darkroom.
It is very likely that this Schneider-Kreuznach Componon lens from 360mm was used in combination with the Turist-FA adapter (shown in the other image) to adapt it to a camera system or for other non-standard optical purposes.
