The Pathé WEBO M is a horrible construction, at least for the one who attempts to service it. Arriflex DS-8 unobtainable Meopta are service friendly, cheaply available, can be upped in optics, D-trajectory claw leaves film in same position as projector. Lateral film guidance ought to be improved, a technician should be able to do that. Large finder view. An article in German language on the Admira 8 G is downloadable from my website. The little Avrora deserves a little more attention. You have only little horizontal parallax between finder and lens. What I dislike about the Canon is the arrangement of the spools at the bottom.

It was the engineer F. W. Planert who converted Pentaflex to DS-8 from around 1970 on. https://zeissikonveb.de/start/kameras/pentaflex-8.html. I have no idea how many of these exist.

Just found a site with more information about the DS-8 Arriflex. https://mimundoensuper-8.blogspot.com/2020/08/arriflex-ds8-holy-grail-of-manfred-jahn.html

The driving members are sturdy enough to withstand such mishaps. What may become bent are loop formers or the claws of the younger models from serial number 100401 on or the lateral guide frame. Else the film can just stall the mechanism but that’s no reason to be worried. To check a spool let it roll alone over a table and observe it.

Mesmerising how Goerz had foreseen an early 21st century hype, albeit the Hypar is just a triplet after the 1896 Cooke portrait lens.

If lens names confuse you, stick to Angénieux. There you have bone-dry designations. S 21, Y 1, Y 2, R 3, J 11, and so on American lens names are pure frolic. Wollensak renamed everything Velostigmat as Raptar. Bausch & Lomb has given Animar to non-anastigmats as well as anastigmats. Eastman-Kodak has cast the veil of Ciné-Ektar over Schneider and Angénieux systems. Bell & Howell had made their name put on lenses from England and France or fantasy designations on German glass. Most Eyemo lenses were made by Wollensak. In Europe you find a Biotar, a Kino-Biotar, a Plasmat, a Kino-Plasmat (different), even a Baltar that has nothing to do with Bausch & Lomb. Care for more exotic names? How about Britar, Nelor, Claror, Atear, Victor (lens, not camera), Victar, Télinor, Maikar, Sytar, Xeen (haha), Stylor, Cine-Prominar (yes), Saphir, Oplenon, Athenar, Votar, Ultra (hahaha), Mirar, Tégéa (très grand angle), Opic, Astrar, Solar, Bolar, Xenagon, Xenogon, Seminat, Tachyplast, Moviar, Polyxentar, Radar, Dygon, Thalia (yeah), Super Six? It’s a funny world.

Yeah, a LEICA thread mounted lens can be fitted, Leitz and Paillard and others have made adapters. LEICA-M bayonet doesn’t work. Although I understand the lust for experiments I want to point out that the Paillard-Bolex H are 1) amateur cameras and 2) made for one, two or three compact and lightweight lenses. To take the quality of a Leitz photo lens to the 16mm screen is almost impossible with the common film stocks. I dare saying that purpose-made C-mount optics are more satisfying in use. At times I get the impression that the motto of today goes Keep it complicated!

Colour temperature matching wasn’t a subject when Angénieux designed lenses. At the time the R 2 was computed still about half of the production was black and white. If you have the 18,5 mm in ARRI mount, you’d perhaps want to add an S 41, 25 mm, and an S 5, quite rare. Do you have a Kodak Reflex Special?

Are you going to ask a question?

The Xenoplan 6,5 mm is a machine vision lens, isn’t it?

Right you are. I was exaggerating from a couple of Schneider of which I’m not certain whether they were still in original state or not. Two Wollensak Cine Raptar 25-1.5 I also had to free from oily mist on the glass and sticky grease on the iris.

Traditionally it is reckoned with five grams of silver per square metre. That corresponds to oz. 0.17637 per 10.764 sq. ft.

would have, not would of. Please.
