Good morning all.
I thought I would toss in my two cents here in redards to camera lubrication. I serviced, overhauled and built motion picture cameras and optics for just over thirty years. I worked with some of the best techs in Hollywood, Chris Condon, Jimmy Beaumonte, Ed DiGuiliou etc. and in that time the only lubes we ever use were the greases and oils made by Losoid (german I believe). So after thousands oof lenses and hundreds of cameras including every thing from a 16mm Filmo to the 65mm Showscan cameras running at 60f.p.s. standard frame rate without a failure due to lubrication I feel confident enough to say that these lubricants are comsiderd the standard in the industry. I'm not saying that the lubes recommended by Arri or any other manufactuer are in any way inferior, just that they are not mandantory. The three main greases we used were 33B for movement gearing, Arri phenolic pull down claws and most prime amd zoom lens rotating and sliding surfaces. BBR-1 for ball bearings an #70 for areas requiring a heavier viscosity lube. The two oils were the standard camera and the hi-speed types. At one point I maintained all the cameras and lenses for the UCLA film school for over five years straight. So I know from experience how these lubes work on particular cameras and lenses on a long term basis.
Anyhow as I said, just the two-cents of an old camera tech.
Cheers, Chuck Colburn
