OS

Sehr frühes seltenes vergütetes Zeiss Jena Sonnar mit M39 Gewinde, E-Messer gekuppelt.

Nr. 2687351, Baujahr 1941, Kriegsproduktion.

Sehr seltenes Sammlerstück, für Anwender aufgrund optischer Mängel kaum geeignet: Frontlinse berieben und Vergütungsschäden, mit Sicherheit weiche Abbildung. Öl auf Blendenlamellen. Funktionen (Fokussierung und Blende) in Ordnung.

Wir haben einen Experten-Kommentar dazu erhalten, hier für Sie einkopiert:

THERE ARE VERY VERY FEW ZEISS LENS WITH THIS TYPE OF ENGRAVING... TO MY KNOWLEDGE A HANDFULL AT THE MOST... (I HAD A LONG DISCUSSION WITH CH. BARRINGER ABOUT THOSE, BEFORE HE DIED)... HE HAD NOTED ALL THE KNOWN EXEMPLE... THERE IS A 85/2, A 50/1.5 (MINE) AND THEY ARE ALL WARTIME LENSES... (NOT PROTOTYPE BECAUSE THEY ARE OLDER THAN THE "NORMAL ENGRAVED" LTM T LENSES) ... MAY BE PRODUCED IN A WORKSHOP OUTSIDE THE MAIN FACTORY... BUT DEFINTIVELY BEFORE THE END OF THE WAR...

WHAT IS SO SPECIAL IS THE DIAMOND SHAPED GUILLOCHAGE... AND THE ENGRAVINGS OF THE DEPTH OF FIELD SCALE...
AND ONE HYPOTHESIS ABOUT THAT BATCH OF LENS IS THAT LIKE ALL THE WARTIME LTM ZEISS THEY WERE MADE FOR THE MILITARY, BUT THAT THIS SPECIFIC LENSES WERE MADE AFTER THE BOMBING OF THE FACTORY... IN A RUSH SOMEWHERE ELSE, FROM AVAILABLE GLASS PARTS ... SO THE SERIAL NUMBER MAY BE 1941, BUT THE PRODUCTION IS A BIT LATER... TRANSFORMING A CONTAX DESIGNED 50MM IN A LTM IS NOT THAT EASY... IT'S NOT THE SAME FOCAL LENGHT (49 IN LEITZ, 52 IN CONTAX)
