The film transport phases of the Soviet KC-4camera:

Here is the B&H shuttle:

Intercinema Corp. in NY was manufacturing co-axial 400ft mags with a detachable torque motor starting from 1968, and under development for 2 years. In the UK, THE CINTRON GROUP of Grove House, London was the importer starting in 1970. In any case, you need two movements, one is for the sinusoidal claw trajectory, the other one for the lateral pin movement, if your camera should have a registration pin or pins. For example, Traid camera (see below) has a claw connected to the front cam frame and separate individual register pin (contrary, claw and pin movement share the same axe in doiflex 16).

BTW, FYI, new and updated documents are available, as well as a new entry about the ACL motors on the Cameras éclair site.

Duncan and Gregg, Were there any leaflets for the AATON 7 and 54 available from Grenoble? I know that there were no brochures containing detailed information like Arri had, but a catalog from 1978. Thanks guys!

Checked today all OK here.

Soviet 16СП (16SP) uses a simplified Arri shuttle clone which has no registration pin.

General attitude was to utilize a combined mechanism that serves the both requirements (exposing and film advancement). But, in contrary, in doiflex 16 we see two individual arrangements. That means two separate cam movements: one for the shutter and the other for the claw. Eccentric cams move the cam follower frames of the shutter and claw lever. Normally, shutter cam follower frames have claw levers in many cameras thus eliminating two separate arrangements.

doiflex 16, certainly, is an interesting camera, which utilizes a combination of mechanisms seen in various cameras. The pull-down claw looks like a simplified Arri 35 claw mechanism, the Zeiss Ikon Movikon 16 except the registration pin. Its obvious that they wanted to keep it simple. When it comes to the spinning shutter and oscillating mirror, well-known combined pull-down/shutter mechanism of the cameras like Emel, Maurer, Triad and B&H was used.

They could not copy, because of the complexity means price increase, then nobody would like to have one with closer prices to the Arri 16S(t). Also the patents were active. https://sayyes2analog.wordpress.com/2018/01/13/doiflex16/ Of course, except the Soviet Union! https://www.flickr.com/photos/wise-man/29629618337/in/album-72157710336572487

Does anyone have the Optasound 116R instruction manual? Would it be possible to scan it at high resolution. Will have it printed out. Sincere thanks!

We are probably dealing with a prototype camera or a camera produced in very small quantities! I searched all my databases and never come across this model. I think the GOIF went bankrupt in 2007.

Hi Jason, That's correct! Gan Guang brand and totally an ACL knock-off. Probably made after 1980. Will find more info for you... That factory also made ELMO-16CL projector knock-off. Gan Guang GF-100/101/102: https://www.flickr.com/photos/wise-man/43849443384/in/album-72157710336572487 The one you found online SX16K was made by AVM (Qinhuangdao Audio-Visual Machinery Research Institute). Also a similar design ST-16 was made by JOC (Jiangxi Optical Complex-Jiangxi Optical Instrument General Factory) Some info on my Blog: https://sayyes2analog.wordpress.com/2015/07/18/prc-cam/ Hope this helps for now. Best, Erkan

Hi Charlie, I sent you an email regarding to ARRI. Hope you get it. Cheers!
