[Konvas] camera frame by frame .... Olivier .

[H. W. Stone]

 About ten years ago I had a "time lapse staging solenoid" drive for the Arri 2b/2c camera, and it worked like a charm, but would be cheaper to build than to buy.

Get an Arri or Panavision brand "flat base adapter" for the camera.  That's made to put the camera motor beside the camera, not under it-- but then, instead of an Arri motor get an off the shelf "staging solenoid" used on sorting conveyor belts, and set it up to pull a ratcheted drive cog mounted where the motor would normally go.  This means you can program the staging solenoid to trip at given intervals, anywhere from twenty or so times a second down to once a month.  The difference is that when it fires it fires fast, and you get a properly exposed, advanced, and handled frame.

If you do get a motor from Clive, it will work, but staging solenoids are interval set items, the motors are not.

HI guys, for this moment , i own a Arri2C full overhaulhed with a 24FPS 
motor (24fps syncro only) and PL mount ...


i will receive my 1000 feet magazine for Arri2/Arri3 .... 


so i will have completed my system with own equipment for tape to film 
....and mount all in a metalic structure with marks for 


1:85, 16/9, and scope transfer 

=0
A 


BUT, i am really interested in a 3 to 4 FPS transfer from stills ... 
(animation or frame by frame transfer ...) OK it take more time but will make 
another option to tranfer video to film for my customers ) 


 


SO i need info about a TOBIN motor for low speeds ... frame by frame 1 fps 
2fps 3 fps .... (like the timelapse ones ...) to mount it on my Arri2C 


I need so a Inverse Baseplate to plate the motor in a side of the camera 
and NOT below ... for more stability ...


 


so any Timelapser have info wich motor TOBIN or other will be good for this 
system ???


 


Bests, Olivier .

"Thee´s a nice zoom lens on EBay these days… Do you 
  know the funny kind of lens mount? Item 220323145688"

  
 

  
Ole,

  
 

  
Yes, that looks like a 16mm "C" 
  mount to me. but there seems to be a sealing ring missing over the rear 
  element, should'nt affect the image though.

  
 

  
I have one identical to above but 
  with Arri standard mount. Mine has "minty" glass and has been 
  serviced.

  
Euros 200.00 to 
  you!

  
 

  
These are nice lenses if you can 
  get a=2
0good one. The 35mm version is stunning.

  
 

  
Rita   (got Uher spares 
  if you need any)
