It came with a TCS TXM-7 crystal sync motor. Have been trying to track down documentation somewhere online but cannot locate it…not even on Tobin’s site which only goes as far back as the TXM-8.

There is a knob on the side, like a rheostat dial, trying to ascertain what it does. Next to it is a hard switch for 24 or 30 FPS….

Anyone on this site have an inkling as to what this dial does? There are no markings by it, nor does it look like any markings have faded.

Cheers,

Or does anyone know what tools were actually in the kit.

My Switars are the non-RX type, and all of them, except the 25mm f/1.4, fit the mounts of other 16mm cameras, like the ACL and Beaulieu R16, and clear the mirrors of those cameras.

The depth-clearance of the ACL and R16 from camera-flange to mirror-baffle is approximately 3.6mm, maybe a fraction deeper, while the 25mm Switar requires approx. 4.6mm clearance. My non-RX Bolex easily accomodates that depth from camera-flange to shutter.

(Somehow, the RX Bolex must also accommodate the beam-splitter prism in front of the shutter, and still clear the depth of the RX version of the 25mm Switar — I assume that lens is the same depth as the non-RX lens.)

Anyway, maybe someone among the pro-16mm cinematographers knows how much clearance the 17mm f/.095 Navitar requires. The lens’s combination of speed, ideal focal length and one-inch-format coverage would make it worth having for an ACL converted to Super 16, or Ultra-16. The ebay seller has the lenses on consignment. They are not on his premises, and he cannot measure the depth of their mounts.

Unfortunately many eBay sellers do not understand this and so it can be difficult to know if the lens is standard or RX unless the seller knows what camera it came from.

I wish I knew which lenses worked as well! Hopefully with this info you can try to ask the seller, though.

All but one of the lenses fit, so far. The one that doesn’t fit has a protruding rear element, like the 25mm f1.4 Switar, that will fit only my non-reflex Bolex.

There is currently available on ebay a Navitar 17mm f/0.95 1″ format lens, but the photos on the auction site seems to show a moderately protruding rear element.

Has anyone tried to use that lens on an ACL, or even on a Beaulieu R16, and found that it will screw down to the camera-flange without having the rear element bottoming-out on the camera’s mirror-baffle at-or-before infinity focus?
