Author Topic: Colour of Lenses. Stephen Furley Film God Posts: 3059 From: Coulsdon, Croydon, England Registered: May 2002 posted 12-14-2015 04:47 PM                     Lenses used to be silver, for a long time most have been gold, but a few are either red or blue. Is there any significance in these colours?  |  IP: Logged Jim Cassedy Phenomenal Film Handler Posts: 1661 From: San Francisco, CA Registered: Dec 2006 posted 12-14-2015 08:19 PM                     I'm going to go out on a limb here, Stephen, since I'm not a lens expert, but I believe the different colors are simply to differentiate between manufacturers, or between different models of lenses by the same manufacturer. That's my best guess. I don't think there's any "technical" reason.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

Schneider went to "golden" lenses pretty much when they went to multi-coated lenses and stayed that way up until the VERY last generation when they went back to a black scheme (with a grey ID ring). I was told the change was actually a cost thing...it was cheaper to produce the black versions than to maintain the exact golden color. ISCO (now owned by Schneider, again), did use red to signify their Ultra-Star Plus lenses that are inherently more light efficient than their golden predecessors the Ultra, Ultra-Star. On the anamorphic side, they used blue for their "Blue-Star" lens to signify it was their best (6-element versus 5 on the Ultra Star or the 4 element of the Ultra/Kiptar).  |  IP: Logged
