  1. This sort of thing is common in astrophotography. Look for something that can control a stepper motor (steps can be so small as to be unnoticeable), and see if you can use that. OnStep is used for mount control, and may be useful itself or offer leads to something that is.
  2. It is the most terrifying movie I can remember. The tale of someone who devolves into insanity and murderous rage will never leave me. The story is made better by the great cinematography and direction, one of Eastwood's best.
  3. I had to resort to Google Translate: Selling a dryer for 8-35mm film of our own production $145 with delivery from Ukraine A new budget dryer for film, this is a copy of the Soviet SKP, sold unassembled, easy to assemble and disassemble, made of ordinary steel - these are racks and 2 rods that hold them, the remaining parts are made of aluminum and stainless steel, stainless steel spokes covered with a polyethylene tube, the approximate length in meters that can be placed for drying 8 mm = 60 meters 2x8 or 16 mm = 30 m 35 mm = 15 m this is taking into account that if there are no empty spaces between the film, the product is not factory made, and to make the product as cheap as possible, there are various minor defects, but this does not interfere with drying the film, shipping is as fast as possible on the day of purchase or the next day, now the mail works quite well, for example, for the USA it is no more than 14 days and possibly 5-6 delivery from Ukraine, ask questions before buying, I will be happy to answer, have a nice day.

  4. Quick google search found this: https://www.newark.com/c/connectors/circular-connectors-components?brand=jaeger Newark is a major electronics distributor in the USA, and they may be able to make a cable to your specification. Not cheaply, mind you, but there you are.
  5. YM Cinema has this take on the situation: https://ymcinema.com/2025/08/08/canon-should-buy-arri/ May help to balance Nikon's buying RED Cinema.
  6. This is a tricky question, because of the dependency on OS, drive selection, and other dependencies. NORMALLY, a JBOD means every disk is independent, with it's own File System (FS). Some like Synology can be configured as a single drive, and used successfully, HOWEVER, there are risks in formatting such a drive; if you lose a drive, you lose all of the data. Better, if you have three or more of the same drive (Model number and sectors), you might consider creating RAID arrays to hold the data. RAID 5 will protect your data in the event of a drive failure. The other dependency is the choice of OS. I use OpenSuSE, even on my laptop. Sounds like overkill, but I have yet to lose data from a drive failure. OpenSuSE uses the BTRFS (Balanced Tree File System, a form of directory management), because it creates its own backups, and can recover data if there's a glitch writing data, which is more common than you hear about. Basically, I create a FS for important stuff like Videos, Photographs, and Documents. Now, each of those filesystems is protected from disaster to some extent, although there's still a risk if a drive controller (the management chip in the drive) burns out. If your collection is more than a few hundred gigabytes (GiB), think about investing in a small RAID system, Amazon has one for $150*, no drives, and then back up your data, put the drives in, and create the RAID volume. The sleep you save will be worth it. Link: https://www.amazon.com/Bay-RAID-JBOD-Enclosure-Storage/dp/B01LYEM3VO/ref=sr_1_46?sr=8-46&xpid=26Zii3FS5mi_S
  7. I have three movies I watch repeatedly: Lawrence of Arabia Doctor Zhivago Shakespeare in Love Lawrence, because I like sand ;-D also, Peter O'Toole is incredible, watch his performance. Then go to the bathroom, and watch it again. Zhivago, because I was thirteen when I saw it in the theater upon its release. NOTHING was as profound to me at that age. Shakespeare because Marc Norman and Tom Stoppard are the best at writing. Period. Exactly none of these movies are AI generated, and I continue to believe that most people will have a non-AI generated movie that will resonate with them, at some point. AI (yes I have an AI workstation at home) is great at finding the patterns in data (including visual data), but it cannot completely generate the same effect that great acting and marvelous cinematography can produce (watch Newman's performance in The Verdict, or Matt Damon's in Good Will Hunting). There will be that segment of the population that will still be moved by a great performance, and it will be some time before an AI can replicate that. So keep making movies, even if you have to use a Blackmagic 17K and a set to Tokina lenses because there's no more Eastman cine film.
  8. Telex (https://en.wikipedia.org/wiki/Telex) was an Ancient Analog Technology™ to enable text messaging across the circuit switched telephone system. Birthed in Europe, it made it's way to the US. By the late 1980's, it was replaced by the nascent internet. Thus, the catalog was probably 1980 - 1990.
  9. I'm not even remotely able to afford this, but what is the aperture of the lens, and what is the exit size of the rear element? Just asking, thanks fo your indulgence.
  10. I typed up a bunch of stuff, then actually read the Wikipedia article: https://en.wikipedia.org/wiki/Normal_lens It gives a pretty good explanation of what would be considered a "normal' lens, so read that first. When i was photographing with a 4x5" camera, getting that normal perspective was a challenge sometimes, but the rules of thumb (FL equal to diagonal for normal, long equal to twice shorter side, WA equal to short side) still are useful. Go find the specs on your film gate or sensor, and proceed from there. You won't go wildly wrong.
  11. Gorgeous. As a long time large format photographer, this excites me like nothing else. Great job on maximizing the potential of the BMPCC.
  12. In my LF (photography) days, I would have loved a set of these. A quick Google found this: https://www.mole.com/
  13. The first law of optics is: 1/OD + 1/ID = 1/FL . Therefore, if you take a lens at infinity focus, the Object Distance (OD), must be at infinity (generally, that's assumed to be 1000*FL of the optic), and the Image Distance (ID) is going to be 1*FL away from the center of the optic. As you get closer to the Object, the Image Distance increases, and thus, for a 50mm lens, if we focus at 5000 mm (5 meters), the ID is 50.505050505050... You can play with this formula at https://mathsolver.microsoft.com/ It'll open your eyes to a lot of reasons why that lens won't focus closer than 1/1000 *FL.
