There’s that image with the German Wikipedia page for the Bell & Howell Company: I took it in 2006. It’s from a set of CIRCUS, a silent picture made then. Olympus Pen-F, Gigabitfilm 40, proprietary developer from the Gigabitfilm enterprise. Here is the full image: The negative size is 18 × 24 mm. I scanned an enlargement on RC photo paper, a little smaller than 18 × 24 cm at 300 DPI. Another cutout from the same enlargement, scanned at 600 DPI: This is a tad bigger than three by three millimetres of the negative. One can see well the scale of the footage counter and the one for the shutter times. There is still a lot more on the negative. The enlargement was not made with special care. I don’t know what you’re talking about.

There is no obligation to use Kern lenses with Paillard-Bolex cameras. D-mount optics were also made by Leitz, Laack, Berthiot, Angénieux, Taylor Taylor & Hobson, ILEX, Wollensak, Elgeet, Kodak (yes), Gundlach, Zeika, Ichizuka, Nikon, Arco, Soligor, Simpson, Chinon, Sun, Hermagis, Zeiss, Steinheil, Dallmeyer, Rodenstock, Bausch & Lomb, Meyer, Schneider, Isco, Astro, and others.

Alright, M 28 then The Yvar 13 mm, f/1.9 is a triplet. There must be something shifted between text and images. The lens shown next to The Pizar 12.5mm (½") F:1.9 is the Pizar 26 mm, f/1.9 for 16-mm. film. The Pizar 12,5 mm, f/1.9 is a triplet, too.

The Switar 36 mm, f/1.8, is a five-glass lens. Positive, cemented achromat (flat common surface), thick negative, diaphragm, positive The filter thread is the M 33,5 × 0,5 mm.

The absolute size is reflected in the price. Optical glass costs more than window float pane and bigger mechanical parts are pricier, too. Medium relative aperture lenses have smaller elements compared to speedy ones which again leads to cheaper products. Mass produced amateur optics are cheaper than professional volumes but not necessarily worse. If you can handle an Animar 26 mm, f/1.9 you get beautiful images. As a keen cinematographer you know what lens you want, a triplet, a four-glass lens, a six-elements design, opening of f/4.5, opening f/1.8, and so on. Depending on the type of camera in question, a heavy tripod Mitchell 16 Professional, a hand-held GIC 16 or a Beaulieu R 16, you gather luxurious glass or compact and lightweight lenses, respectively. One thing is important, the mechanical quality of diaphragms. Regardless of size some makes hide second-class stuff. It comes down to single products and series whether the diaphragm is robust or weakish. Unfortunately.

No, I have never seen a Ciné-Kodak Economy with an electric motor but the US government grasped as much of cine material as it could from 1942 on. Eastman-Kodak seems to have complied with enquiries. No idea about tension. Spiral cord is younger, 1960s.

Pardon me, wanted to say barrels. Casings?

There are mirror shutter reflex-finder cameras for Double-Eight film. The first one was the ERCSAM Camex 8 Reflex, presented on May 6th, 1955. In 1956 came the Armor 8 C (double-prism block like Paillard-Bolex but slid in and out before a take). Then the Nizo Heliomatic 8 Reflex in 1957, the Beaulieu Reflex 8, 1959, and the Pentaflex 8 in 1960.

They’re of the same five-elements design. Only the mounts are different.

The original pins were made by Spirol. A couple years ago I inquired with Spirol about manufacture of these. The answer was minimum order 200,000.

Fomapan Reversal was introduced in 1950, named R21 initially. Eastman-Kodak made Panatomic-X available in 16-mm. and Double-Eight in 1947, ASA 32. Super-X and -XX came out before the war, Plus-X negative in 1938. You still had the early Kodak Safety Ciné film which was orthochromatic reversible and Kodak Panchromatic Safety reversible. Bauchet introduced a Super Panchro reversal in 1939. Gevaert stocks since 1932. Schleussner and Mimosa since 1936. In Britain there was available Selo ortho. reversal in 9.5-mm. in the twenties until 1928. Ilford Pan F from 1956 on. Konica made 16-mm. film from 1931 on, Double-Eight stock since 1933. The Kodak reversal stocks on grey and blue base began being used from 1954 on. Developers used to be hydroquinone-metol formulae. Newsreels were 35-mm. with 16-mm. exceptions rather than the rule. Blow-up and reduction printing was done since the early 1930s. You had a clear-cut distinction between professional commercial cinema which used standard film and the substandard amateur or, to some extent, scientific cinema. Experimental cinema happened on standard film. Artists used the spring driven Sept by Debrie, ICA Kinamo, Cinégraphe Bol, Bell & Howell Eyemo, De Vry. 8-mm. was considered a purely home movie format. Kodachrome became available in 16 and Double-Eight in 1936. The finer-grained Kodachrome II came out in 1961. Why emulate something that won’t be recognized as original? Will you project? Will you use non-bloomed lenses on camera and projector? Do you have an idea of the light seen by the public, incandescent, carbon arc? Do you want your images go lost in the sea of LCD displays like all others? Cinema is something apart from computers and data. Films can be projected without electricity.

The 1962 NS P 400 has a pair of fixed pilot pins like the Bell & Howell 2709 or an early Mitchell, closer to the Mitchell AA movement which also pivots around a shaft above the gate. https://cinematography.com/index.php?/forums/topic/72258-mystery-camera/ https://archive.org/details/americancinemato43unse/page/38/mode/2up?view=theater&q=Newman
