  1. Anyone know what's going on with the Adelie? A few weeks ago, Logmar's site had a countdown to a major announcement. Now, it's gone, and the Adelie blogpost is deleted.
  2. CP-16 batteries are hard to find these days, with Du-All being the only place to get them, and many resorting to DIY solutions. Re-celling an existing pack has previously been tedious and difficult. I'm happy to say that this is no longer the case. BatterySpace currently sells the custom Powerizer battery pack that Du-All uses for their new batteries. It is a 19.2V 1000 mAh NiCd battery pack, compatible with CP-16 chargers, but providing twice the energy capacity as the original NC-4. https://www.batteryspace.com/custom-nicd-battery-pack-19-2v-1000-mah-offset-2x8-with-open-end-wire.aspx Best of all, it is a single, pre-assembled pack, you need only to put it in and solder the positive and negative terminals. I'm extremely clumsy at soldering and making a battery pack by hand is beyond me, but for me this was a quick fix. I'm hoping to make some 3D printable files of the battery case too, so you can print your own.
  3. Thank you. And yes, I did do it with only my fingers! What are split reel flanges?
  4. After seeing Dune the other day, I'm inspired to try and replicate the infrared cinematography on film. Rollei sells 100ft bulk loads of infrared film, but from the shape of the box I suspect they are on a 135 core. I've run into this issue before. Arista 100ft rolls come on a film core, but Kentmere rolls come on a 135 core. I've hand-rolled film from one to the other before, but it's tedious and the film came out scratched in development. Does anyone have experience spooling 100ft of film from one core type to another? Should I try to make a 3D printed machine to do it? What's the best way to prevent scratches?
  5. Hi, could you share some pictures of the large format lomos? I am interested in them potentially.
  6. https://www.ebay.com/itm/226038623169?itmmeta=01HRP70HK9FB7V20AKZRPQEGKG&hash=item34a0f3abc1:g:yR8AAOSwbfpl7QzZ&itmprp=enc%3AAQAIAAAA4EJkNRjCB9smXzo2GtTI79%2FDij1%2Bas%2BzXPNMXGwCDf%2F7tVO8Ke0s384o%2F3oTzocL7ahQoJ0JenJ2feW7HDHBZX7YwxumGGYqdPDzoNb408Up78a%2BVPCGrUvM5rhoep9hY%2BeMs9PimVKARHR1sWg1XvNXvj4K2TUMqDoI2V64jq%2BQ2gLDYojZ6toc%2F%2Bj2eSDETnFEUULX%2FZRhNeRp5UE5iYZVAtb%2BOoi4EFnbACQfyFq7xXpeuSTN8NCU3at4l5Fn3%2BD9FoH2L%2BRAN2kEOmmnPcjImms3KzpvJRNbZVh82YPe|tkp%3ABk9SR9iZgsfFYw Check this out.
  7. I'm aware of the Wilcam W-4, the Fries Ultra 70, and Bruce McNaughton's 15/70 camera. Logmar is also building one now. Some of IMAX's own cameras are branded MSM, which means they were built by Marty S. Mueller. I don't know about their other cameras though. There's also a Photosonics handheld camera that shoots 14-perf 70mm at 22 fps.
  8. Dear Olex, What is the cost to rehouse an OCT-18 lens to PL? Thank you
  9. This is quite a fascinating camera. I believe NASA used these to film rocket launches. They used giant military tracking rigs, though maybe a gear head from the Mitchell era will do the trick too. You will absolutely need a machine shop, because it likely uses Type 1 aerial film, you will need to modify the pulldown claw and registration pins to 65mm perfs. CinemaGear can almost certainly do it for you, but it will likely be pricey. I have a PhotoSonics 10B, another NASA 70mm camera I'm currently trying to convert to 65mm. I specifically got the rotating prism model, because I feel more confident in my ability to design replacement transport wheels with new perfs than to re-engineer a Mitchell mechanism. These cameras' motors also run on 208V 3-phase power. You will need a special generator to get them working in the field. This camera is not practical for narrative work - but for documentary recording of events like rocket launches, volcanic eruptions, etc, with a proper crew, it could provide beautiful images.
  10. That's a good find! The fellow who was looking to buy a 16mm camera the other week should consider this.
  11. Does anyone know what the mechanical details of the threads on this mount are?
  12. CP-16 to TS would be great for me - as would OCT-18. Although maybe I should just send my old Lomos to be rehoused already.
  13. Not directly related to film recorders, but the talk of those big high-maintenance machines reminded me of the Spirit DataCines being sold for $9,000 these days, and how this forum was dissuading people from getting them. Hence my mind drifting to more convenient machines like Cintels. What's the workflow like with a ScanStation? I've never used one.
  14. It's not fake to my knowledge, it's a fellow on Facebook named Jamie Welton, https://www.facebook.com/groups/2248960670/user/650315100/ This camera is also listed by him on eBay: https://www.ebay.co.uk/itm/364755545778?itmmeta=01HR0NS4Z0VZ3XV17HNVVFVQZ3&hash=item54ed1feeb2:g:B~IAAOSwXPpl3OoS
  15. Man I wish Blackmagic would make a Cintel with a new imager, and perhaps an RGB illuminator and monochrome sensor. No other professional scanner is plug-and-play like that, getting an imager capable of 4k S16 scans would make it perfect for my use.
