  1. According to this source: http://www.film.project-consultant.net/html/quarz___zenith.html there is a fixed prime behind the mount, so the Meteor zoom is sort of an adapter lens. A normal zoom wouldn't work. The earlier Quarz DS8-M had a similar fixed prime with a screw mount that took wide and telephoto adapter lenses, and I think the later model DS8-3 has a fixed zoom?
  2. Internal light meters were more useful for news gathering or documentary work, but as video finally replaced film for news gathering during the early 80s and professional DPs preferred to meter themselves, the inbuilt SR2 meters were often removed, or the cameras were sold without them fitted.
  3. A film speed selector is only needed when the camera has an internal light meter - yours looks to have had that removed, which was common for SR2s. You'll need to use a light meter. Some SR2s also had the standby/run lever replaced with an on/off slider. The mount is Arri Bayonet, and the camera could be Standard 16 if it wasn't upgraded to S16. If you remove the mag and take a quick photo of the gate aperture we can tell you.
  4. We talked about using modern lenses on film cameras in this thread: https://cinematography.com/index.php?/topic/78728-using-modern-pl-mount-lens-on-film-cameras/&tab=comments#comment-505906 Tyler mentioned that the Rokinons didn't clear the housings of certain film cameras like the Arriflex 2C and 35-3. I wonder if that means they would also have problems with a 235?
  5. 2K or 2.5K windows on RED sensors can use S16 lenses, as well as 2K centre scan mode in some Sony cameras. Alexa Minis and Amiras also have a HD S16 mode. Natively S16 digital cameras include the Digital Bolex, SI 2K and Iconosop A-cam dII, as well the Blackmagic mentioned.
  6. Zeiss Compact Primes should work fine on a film camera. Zeiss even mention their compatibility with both film and digital in their promotional material, but you could contact them to make sure they definitely clear the housing of an Arriflex 235. The only other lenses I can think of in that price bracket that are around 1kg or less are the Sigma primes, which should be fine optically but again you might want to check that they clear the camera housing. Maybe take the camera to a rental house and test what they have. You might find renting an older lens like a Zeiss Standard Speed is an option.
  7. Hi Stefan, does that translate to 6V DC or 8V AC? Do maybe 6V is best?
  8. Well, there you go, I must have tested a 12-240 with a Mutar back when I worked for a rental house that had those items, and found that it worked.. The Optex "Colcine Super 16" extender which I said had the most room would be PL mount and a different design to the Bayonet mount Optex extender which is the one that didn't fit the 12-240. You could theoretically use a PL adapter on the zoom and then use the Optex PL extender I guess.
  9. I don't have one handy anymore to test, but it should fit. The main issue is whether the lens optics protrude too far out the back and hit the optics inside the extender, but I believe the 12-240 doesn't protrude as far as the Zeiss 10-100 that the Mutar was designed to accept, so you should be OK.
  10. I think you're confusing the resolution with the price.. The cheapest Scanstation is over $50,000. Blackmagic brought out a "budget" scanner for $30,000 a few years back. Moviestuff makes decent 8/16mm scanners for the home enthusiast market for under $7000. There are plenty of threads here about people making their own scanners if you're the tinkering sort. I see Tyler responded already..
  11. If the camera flange depth is off it would only throw out the focus scale, it shouldn't affect viewfinder focussing or focus assist which is reading off the actual image. It's unlikely to be a lens problem if it's happening across different lenses. Could be a very dirty sensor cover glass or more likely some issue reading/displaying the files. Omar, do you have an experienced 1st AC or DP to help you set up and record some footage to make sure the camera settings and workflow are correct, and corroborate your feeling that the images are "softer than they should be"? Could you be used to images from a different camera?
  12. Bayonet mount lenses will not fit in a Standard mount. The other way round works (since Arri designed the Bayonet mount later and made it so that the earlier Standard mount lenses could still be used), but if you have a Bayonet mount zoom you need a Bayonet mount extender. Or a PL mount extender and a Bayonet to PL adapter. There is no Bayonet to Standard mount adapter.
  13. Sorry I don't have one on hand to test and can't remember off the top of my head. Maybe 20 or 25mm?
