The SOM Berthiot C-mount lenses that I have use a C-mount that's spring-loaded. The orientation of these lenses on the camera is adjusted with a tool that looks like an oversize bottlecap (it's about 40mm in diameter) with four prongs on the underside set at ninety degrees to each other. These prong...

The Bolex COTAC external battery container (see http://www.rockycameras.com/ekmps/shops/rockcameras/images/-bolex-h16-ebm-esm-motor-bolex-h16-ebm-esm-battery-container-19.99-%5B3%5D-76109-p.jpg) has two mechanically identical receptacles. The plug of the Bolex battery charger thus fits both receptac...

So, your cable pushes the switch without problems?

Yes, the cable actuates the switch perfectly. I think it's the "official" cable release you suggested ought to exist.

. . . strange that the Bolex did not produce "official" release cables for this case, it is clear that that little hole on the Rexofader blade was left in anticipation of that. I found a Bolex cable release that's a perfect fit for the Rexofader. Sheathed in black plastic, it's about 70 cm in lengt...

It's a version that has an angled tip, but there's nothing special about it. You'll just need to find a cable release that has enough 'travel'. I'm sure there are many of them. I'll look for others that may work (I've dozens) and let you know what I find.

Using a Gitzo cable release threaded into the Rexofader, I was able to operate an H8 RX4 with the Rexofader functioning in single frame mode. The cable on the Gitzo extends about 27mm from the threaded nipple, and it's in no danger of breaking.

Thanks. I found the bulb for $15.99 + $5.45 shipping at Amazon. The price at Van Eck for the same item was the equivalent of $34.60 + $29.21 shipping.

Can anyone tell me what bulbs are suitable for use in a Siemens 800 regular 8mm projector? The 220V 50Hz machine - Typen-Nr: Sf. P 8.1 - seems to accept lamps of 250W, 375W, and 500W, but I can't find the bulb designations. This isn't the version that'll operate on 110V 60Hz.

The bottom of the shaft is tapered, and I was concerned the edge of the reel might rub against it. A Neumade 800-foot 16mm metal reel clears the base of the rewinder, but only by a millimeter or two. I wouldn't want to have to wind 800-feet of 16mm film with the tiny crank, however. A 400-foot reel...

Neumade 16mm 800-foot metal reels I've got are 10½ inches in diameter.

The spindle is 5½ inches above the base, so an 800-foot reel will fit.

How do you see these three lens with an adapter ring 32--->37 + filter? I do not think that it's risking of vignetting, even with the wide. I expect there would be no problem, but the only way to confirm that is to buy the adapter ring and a filter (they're not that expensive) and expose some film ...

I use Ronsonol Lighter Fuel, which contains naphtha.

It's true, Series 5 is Ok, but I don't remember if 32mm is Series 5 or Series 5.5.

A table comparing sizes of series filters is included here - https://www.apotelyt.com/photo-accessory/series-filters.

Thanks, Nicholas.
