  1. It's the filter. Remove the lens, take a cotton wool tip or so, and remove the filter by gently pushing it out from the inside to the ountsinde (c-mount thread). There are two, one KR15 and a clear one, they are moved by the filter key in the grip. You can remove the c-mount thread plate before, peel off the black cover and remove the 4 screws. Is easier then. Afterwards for you need a KR15 filter for Tungsten film at daylight. May be, the lengs must bei collmated after the procedure, but in most cases it is fine.
  2. Be careful, ONLY 4,8 V Batteries may be used!!
  3. Achten Sie darauf, dass die Kamera nur 4,8 V Batterien benötigt!
  4. It must have the gear for the aperture and the zoom. Will work then.
  5. Dear Martin, here is an excellent tutorial by Friedemann Wachsmuth! The Adox cartridges are simple to open, as there is no glue, and once the delivering core is mounted and the film threaded to the pressure plate, the cartridge is light safe and the film can be fixed to the uptaking reel outside the darkroom.
  6. Tage off the cover of the sync axis and start the camera without battery, then move the axis carefully with a small screwdriver. Might be dried lubricant, then try again with the battery connected. In case of a short circuit, the motor fuse might be melted. It is on the circuit board under the speed knob, just a small wire that is soldered.

  9. Had the same problem on my 481 macro. First of all, you must remove the cover with the switches, 4 tiny screws. Remove the plate and have a close look at the contacts, that might be dirty or even oxidized. First step is to clean them carefully, with some contact spray on a cotton wool stick, do not spray directly into the camera!!! Second, it can be necessary to bend the contact (arrow on the right) that is soldered with the white lead and moved by the lever with the plastic cap - just a little bit to reduce the force necessary to move the contact arm. This finally helped to cure my Nizo 481. More instructions for DIY Nizo repair see here: https://www.filmvorfuehrer.de/topic/22741-diy-nizo-reparatur (in German)
  10. The easiest way to get gelatine filters for the Bolex in all colors and for a lifetime (!) is to order this little booklet from Lee Filters. Maybe it is for free in the US, but you can buy it on Ebay: https://www.ebay.de/itm/323904610725
  11. Dear Derick, some R16 have an automatic exposure or and all a TTL exposure meter, so with the battery handgrip it is very suitable for street shooting. The Bolex is much slower and the spring drive mostly leaves you alone when the situation is on the peak. Have a nice rendezvous with the 25 years younger French lady, you won't regret it!☺️
