  1. The camera would need to be adjusted to account for the glass in the optical path and you would need to install a clear filter when the diffusion was not in use or else the focus of your lenses will be affected. I worked on a show that did rear diffusion, depending on the scenario or how often you'd expect to change diffusion it can be a little bit of a pain since you have to pull the lens to make changes and take care to not introduce dust/debris. We would run one diffusion during the day and another at night generally of the same strengths so changes were not very often. The benefit / reason we did rear diffusion was to remove the unwanted filter flares / reflections that can occur with front filtration.
  2. Title says it all, looking to buy a motor for an Arri 2c/2b with the transfer gear. Would prefer the variable motor but open other options, DM if you're looking to unload one. Thanks!
  3. Hi Steve, I got it half working before I got sidetracked by work and completely forgot about it. The concept is simple, a relay that is activated when a flip flop circuit receives the momentary pulse from a FIZ unit that uses Arri style single pulse to start/stop cameras. Sometimes it would work perfect, sometimes not at all, sometimes it would trigger the relay as I was inserting the the connector from the FIZ unit, that's about as far as I got haha. I'm sure someone more well versed in electronics could solve this far easier than me tinkering on nights and weekends.
  4. Ah I figured that was likely the case, thanks Dom!
  5. Hoping one of the camera technicians on the forum can chime in on this because my googling hasn't brought me any answers. I'm familiar with checking and adjusting flange depth on film cameras with spinning mirrors via a depth gauge kit. I'm trying to understand what the procedure would be for checking flange depth in a camera system that uses a pellicle / beam splitter for their reflex design, like a Bolex or certain Mitchell reflex cameras. Situations where a depth gauge would not be able to go directly from mount to film plane. Thanks!
  6. If you happen to have a full aperture scan of your most recent footage, take a look at the relationship of the perfs to the frame and or the frames to each other. If it looks like the space in between frames is varying or if the relationship between the location of the perf and the frame is varying then the registration is off. If the perfs and frames are both moving but their relationship is constant, it's the scanner. If time and money allow shoot a proper double exposed reg test.
  7. Something to consider, the Abakus (1.32x) and HDx1.4 (1.4x) adaptors would make the 3.9mm effectively a 5-5.5mm T2.8-ish + any softness or CA an optical adaptor may introduce. If you're only after an ultra wide lens for s16 you may have an easier time hunting down the Optex 4mm T1.8, Optex 5.5 T1.8 or Century 6mm T1.9 w/ the front 4.5mm adaptor.
  8. It does, a few were just auctioned off a few weeks ago from VER/PRG https://www.soldtiger.com/m/lot-details/index/catalog/430/lot/59467/Zeiss DigiPrime 3.9mm T1.9 Cine Lens?url=%2Fm%2Fview-auctions%2Fcatalog%2Fid%2F430%3Fpage%3D8
  9. Have you tried paging through the mode while it is connected? There should be a display for SU which is for when the external speed control is connected. If you hit the phase or run button on the RCU does the camera respond? When set to CAM mode the RCU should just act as a normal external display. In RCU mode it will override any changes made on the body itself.
  10. The camera needs to be set to the PS/CCU mode, the small switch under the display.
  11. I've never seen them for sale before but I have come across them in a few differently styles before, I'm assuming these were custom deals from the rental house. Double stick / snot tape it around the edges of a normal filter tray if you cant find a net frame and want to be able to on / off it. Depending on your focal length you're still going to have to stretch it over the rear if you're going wide, front netting will be visible on the wide end.
  12. When you say mag port cover, do you mean the magnetic gate cover or the rubber magazine loop protector / throat cap?
