  1. I update this post, because I could look spools at the open camera: With 7.5m or 10m spools the slowdown is only visible at 24, 32, 48, 64fps, and when the spring load is running out. With 30m spools it is visible at all fps (maybe it has to drag more stuff), but always towards the end of the spring load. This is what I see "by eye", but I don't exluce slowdowns at other fps or winding moments. Does the camera need lubrication? Any advice?
  2. My Bolex H8 REX4, at low speeds, 12, 16, 18 fps, "slows down", but in very short moments. Do it need a greased one? It started doing this after months of not using it, it didn't happen before. I'm shooting a test film to see what comes out: if the camera slows down in short moment, I should see sections of the film faster or much brighter? Thanks.
  3. I have an old 16mm Karel Zeman short that has a LIGHT vinegar smell, I don't know if it can be a principle of vinegar syndrome (acetosis). How do I behave? I have never had films with vinegar smell. Does a pass of Filmguard help it? Thank you.
  4. Simon, is it a publication? Could you tell me more? Thanks! 🙂
  5. Maybe some amateur work, but perhaps impossible, the distance between sound and image would be distorted. Ah, does anyone know if labs could/can perform on commission optical tracks for private customers? If not in Super 8, maybe in 16mm, etc. I knew of laboratories that can make FROM optical track to magnetic track, but not vice versa. And not being able to do any kind of optical track on private films, even if the customer provided an audio base. Am I wrong?
  6. Mark, do you know if there are super 8 optics sound film that run at 18 fps instead of the classic 24 fps?
  7. Sound/picture distance is 18 frames for Super8, 56 frames for Standard8 (value respected by very few biformat projectors). Is there a sound/picture distance even for the super 8 optical sound? Is 22 frames? Thank you. P.S. Let alone, the Normal 8 sound optical machines (Toei, etc.), too few and too experminetal, but if someone wants to enter the explanation...
  8. Rob, when the claw doesn't take the hole in the film, did you try to remove the pressure plate and fit the claw with the nearest hole (and handling the loops a little)? If after doing this, the film goes, it is perfectly normal, the K3 often needs adjustments to the loading. Even the instruction manuals show the thing, and I have to do it myself with my K3s. If instead the problem can continue even by manually hooking the film with claw, there is some problem with camera.
  9. The dirty one could also be a residue of the foam, often in K3 there is that kind of residue. However, Ruben's indications are excellent. On loop formers: I had two K3s, one with and one without, but I never found any differences, both didn't give loading problems (apart from having to move the film by hand if jammed during the load) or scratches during shooting .
  10. Anyone use old Soviet films on types of cameras? Certainly expireds, but they have the advantage of being already cut in N8. In my case, the daylight spool must be transferred to that of Univex. Even if I believe we should do the same thing for the cartridges of the Ekran-8.
  11. Hi, I've had a Davis & Sanford MAGNUMXG13 tripod for years. Many months it stopped when moving it horizontally, so I disassemble and cleaned it, leaving a layer of litihium grease. Then, It worked well, but the horizontal movement is too fast, I would like it harder. How can I do? Thank you.
  12. I'm testing with my Univex A8 and test film, a fun camera! I'm always looking for other lens, the Univar f5.6, besides being slow, doesn't have, as I said, a table to understand the distances, the depth of field and the parallax. Even if with those openings (F5.6 --->) the depth of field it's very long. Martin was right about the deformations of this machines: mine had two slightly bent parts, the side cover and a piece in front of camera, but I fix them without breaking anything.
  13. Daniel, Ruben is right, and I add: the more experts of me will confirm it, the Bolex H, typically, impressed a film image a little bigger than the one you saw on the viewfinder. I also have a Rex4 (H8), I can't tell you if it's bigger than 10-13% (which seems a bit too much), but a little bigger yes, it's true. Instead the viewfinder that moves might be to be reviewed, if it moves very deeply it could give you a wrong focus, slightly changing diopter, if it moves in other senses it could give you a displaced image composition.
  14. Wow, curious and interesting effect, it looks the same as the films developed with caffenol.
  15. My Univex A8 has arrived. Very pretty camera, small and heavy, very aesthetically pleasing. It's in excellent condition, runs very well, a bit more noisy than I expected, but it runs smoothly, very fast, I think it holds 16 fps well, and slows down more than good, without acceleration and deceleration. The Univex F5.6 is very small, it has a particular kind of function (who knows it knows it, if someone is curious, I post a picture). It does not have only ONE mark for the stop selection, but FIVE, one for each stop, so the lap making the ring iris is minimal (1/8 inch!). I also tried the two reels with a test film cut with the Lomo cutter, running smoothly. Obviously, having two take-up spools and not an original 1x8 film, I will have to insert the film "inverse on the hook of the spool", because it is made to receive... I don't know if I can explain myself... However the manual is clear, shows how the two spools are wrapped, no problem, the unexposed film wraps itself well even on a take-up spool. I will buy a Fomapan R100 2x8 10m, to cut in two in the dark with my Lomo cutter, and I will use an external lightmeter, the table included is only approximate. The only thing: the manual does not mention how use camera with parallax. At what minimum distance should I expect a decentralized vertical image? So, a table of distances referred to Univex F5.6 would have been useful... Does anyone have one?
  16. David, usually the K3 viewfinder has a yellowish color. Yellow of your photo, however, seems very strong, but maybe it's just the effect of the photo. If you are looking for "yellow(ish) viewfinder Krasnogorsk 3" on Goolge, you will find various relevant results. I had two K3s, the first had a fairly yellow viewfinder, the second a little less. Obviously, it's a viewfinder problem, nothing yellow will be imprinted on the film.
  17. I wouldn't have said that Canon was the best! Of course, the Bolex H viewfinders are always dark and small!
  18. I took a working Univex A8for $ 5. 🙂 I wanted to take the Ekran, but I was attracted by the offer. The seller said it works well, let's hope so. The purchase was also driven by the fact that it has 2 empty spools, since unexposed film on a Straight 8 reel would be almost impossible to find (Svema apart), and so I will be able to use new film, cutting the Double 8 in two parts. The only negative thing: it has an Univar F5.6, but I hope to find at least one F3.5 Wollensak to replace it. Obviously, for professional use, I also use the Double 8, mainly with a super-equipped Bolex, but I have the curiosity for this format. I keep you updated!
  19. Simon, the Univex with the optical viewfinder have a good view? I would also be willing buy version with the aerial viewfinder, it's a "divertissment" experiment", not for quality.
  20. I also like aesthetically, Simon, and I trust your recommendation, I think it's also good as a mechanic, you know the well it. Unfortunately this is also very rare, the very few that I found did not have cartridges Between Univex and Ekran-8 which one would you choose? In your article you name Krasnogorsk Kama, but I didn't find it. Do you have any pictures? EDIT: Found. It looks very solid, who knows the gate...
  21. Very rare, I can't find even one of 127-A / B. Maybe better this way, I think it wouldn't be in good condition. The Revere is interesting, but the Straight Eight version is much rarer than the Double 8 version. I saw that there is also the Double 8 version with cartridge, in which one was turn the side of cartridge. I think I'll choose Univex, but I have to be careful with the lens, 5.6 is really too dark. Version with optical viewfinder is not bad!
  22. Thanks to both, you described all the straight 8 cameras available. From an in-depth research I noticed that the Ekran and Univex A-8 are the most available, the magazines are also easily sold for Soviet, same the spools for the second. However, even on an aesthetic level, I would prefer the Revere (rare) or a Bolsey (rare and very expensive) For the B&H, the ads never specify the acronym well, and it is not clear if sell the Double 8 or "Single" model 8.
  23. Thanks Simon, I use the Google Translator. I have seen also on English Wikipedia , the format is called Straight Eight and they are Agfa Comex, B&H, Komz Ekran. I'm curious, I'm trying to look for something, maybe without a cartridge, because having the cartridge is even more difficult.
