Steven, I looked at all that - cleaned, tightened some things up and etc. Mine runs choppy at the same speed in all speeds then shuts down immediately after. Sync light never goes off. Someone said that the IC's (which are not made anymore) dry out and malfunction. I wish I could find a fix.. this camera is so primo to me. Jane

I would love to get the schematics and parts list as Andy said. My control board acts erratic. Renders the camera unusable. Hey Michael -- where are you? Get back to us..lol Jane

Hi Michael- Haven't talked to you in a while. I have another CP16 with a bad board. It won't run properly. I would also like to get whatever you can help me with to build my own boards that you designed. Please tell me what you need for me to send $. I would like to make two boards for both my CP's. Thanks, Jane janemargo@yahoo.com

Hello... I have two CP16r's both with different shutters. One is the half moon and the other is a bowtie. I was wondering what issues I would encounter in attempting to match footage shot using both cameras. Has anyone done this and what were your results? Anything anyone has to offer on this subject is greatfully welcomed. Jane Margo

Well I was referring to the TK27 and TP66 projectors. It was a monolith setup...lol I maintained (which was a lot..lol) and operated that one until 1985.

You are correct John about following suite with the tube sizes. I maintained one of the broadcast telecine units from RCA. The camera had 4 1 inch tubes. I didn't think there was anything bigger but the chip makers are doing new and innovative stuff for this technolgy we are talking about like the Arri D21. The Super35 chip's image area is that of a 35mm film apeture. I will try to find where I got the info but I had a chart that showed everything from super8 dimensions, to consumer camcorder 1/4" ccd's to the new breads of Sony cmos applications and all the way up the line. The chart allowed you to go to and film format like Super16. It has the diaganal dimensions as well as H x W and gave reference to what size (type) chip you would need. I'll return with that link so you can see. Now if the chip even exisits maybe another story. I haven't gotten that far yet. But I have rethought some of this and I wonder, does the chip really have to match the size of the Super16 apeture? Could a condenser lens be installed coupled with the collimer adjustment give the targeted image onto say a 2/3" chip? Jane P.S. Does anyone know how to get my profile pic to show up in the forums?

Ok, here is something I know. First of all, camera manufactures advertise the chip type (size) There is a difference between the type and the size. A 2/3" cmos chip for example does not have a 2/3" image area. The diagonal dimension of the super16 aperture is approximately 14.54mm. To accomodate that image area you would need a 1-1/8" cmos chip to do the job. I didn't calulate the actual image area... lol but I know that chip would almost perfectly fit the Super16 aperture. The Super35 cmos chip in the Arri's is massively huge. If I am wrong about this, please somebody let me know. Thanks, Jane

Thank you everyone for your wonderful replies. They do give encouragement. I'm going to test a few things with what I have. I have a cannibalized Frezzi LW16 with a dog leg viewfinder on a Ang 9.5-85mm lens. Getting the imager properly with the lens is my main goal. I'm not worried about the shutter at this time until I can look further into a mirror reflex. Just the idea of having a true optical viewfinder is enough to get me excited about this for now. Then I'll go from there. Thanks again Jane

Hi, I think this is my first post. I have some really off the wall questions concerning the cmos imager and using a mechanical shutter. I don't know how Arri has done it but from what I have researched, shutters are needed for still images but there is a fail when it comes to shooting video on still camera. So then the cameras are designed to make the shutter inoperative during video mode. This is my question. don't laugh. Does anyone here know what the possibilites are of devising and arrangement with cmos imager into a mirror reflex film camera such as Eclair, CP16 or any in that class. I know, why would you want to do that? My first thought was, I see issues stated all the time about DOF and the new HD video cameras and third party lens adapters for 35mm lens. I have to question why does it have to be this way? I get excellent DOF and beautiful images from my CP16 with an Ang. 12-120. My thoughts are, why wouldn't be possible to have everything as in the Arri D20/21 in a cinematography camera only in a Super 16 version? Basically, can a cmos imager work on a mirror reflex optical path arrangement using Super16mm lenses? Of course, this would be a new invention. I'm no expert in this technology but I do have a bench with all kinds of cannibalized cameras and parts and I do engineer some of my own parts and accessories. Ok, I know this was long winded. Hope someone can enlighten me.
