  1. 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.
  2. 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.
  3. Hi Stefan, does that translate to 6V DC or 8V AC? Do maybe 6V is best?
  4. 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.
  5. 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.
  6. 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..
  7. 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?
  8. 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.
  9. Sorry I don't have one on hand to test and can't remember off the top of my head. Maybe 20 or 25mm?

    Unless retro-fitted the Moviecam SL power socket was actually 4 pin XLR, as detailed in this thread: http://www.cinematography.com/index.php?showtopic=65058 There's even a diagram from the manual of the connector wiring. Hopefully the camera has a power cable with the right connectors. But the OP was asking about the battery, which was usually 24V 3 pin XLR. Often easier to get a cheap battery (with different chemistry it could be a little higher than 24V) and solder on a 3 pin XLR socket. Pin 1 neg, pin 2 pos.
  11. The wide end won't cover but longer focal lengths should be OK. It depends where you set the focus but for complete S16 coverage even at minimum focus I think you need to be over 40mm. At infinity you can go wider.
  12. Well in the interests of balance I should point out that rental companies around the world serviced their own Arri cameras for years as well as third party repair facilities. Arri regularly held service training sessions for technicians and provided parts diagrams. We had thick folders full of electrical schematics detailing every component of the many different Arriflex models, and the electrical techs often did component level repair on boards, so the idea Arri were trying to "stop people doing repairs behind their backs" is ridiculous. You just had to have had some training and invested in the jig, tools and manuals. There aren't too many companies that still support products they released 25 years ago, but there are for sure still technicians around who have the knowledge to fix some of these cameras. Apart from the 416, which I agree has less support because of it's limited numbers and complexity, in my experience Arris are generally far easier than Aatons to get repaired. Well the Arricams I used to look after as a rental house service manager worked pretty flawlessly for the 15 or so years we had them working. The few times we had issues were caused by clients mistreating them, dropping them or plugging in dodgy cables. They're superbly engineered machines. If you were trying to service them yourself then I don't doubt you had problems. Or maybe you were using a technician who wasn't quite up to the job. In any case, I've never heard anyone else complaining that Arricams are unreliable. By the way, when you say "..even after servicing all them, one of them still.." , servicing cameras is not a sign of deficiency, it's something they need anyway. The point Charles was making was about the 416. We've hired one out several times here at Panavision without problems, and it seems like another very well made machine to me, but as Charles pointed out, there weren't many made, and the digital transition within Arri occurred pretty soon after, so they don't have the same wide technical support of earlier cameras. I certainly never got any training on it, whereas I knew SR3s and Arricams inside out.
  13. Kipon make a range of larger format speed booster adapters, but even for something like Hasselblad V or Pentax 6x7 lenses with long flange depths the deepest mount they adapt to is Leica M, which is still about 24mm shorter than PL. Either it's not possible, or the market for PL is too small. I suspect there's not much point adapting those lenses to PL anyway, with so many native PL lenses out there.
