Seems like a simple question.

I can't find anything below 100 ISO?

Yes, 2378 is low speed but engineered to be extremely high contrast to obtain crisp track wave forms on optical tracks.

2234 is Panchro Dupe neg, 2366 is Inter positive (Ortho; can also be processed as negative) and 2302 Fine Grain Positive (Ortho; can also be processed as a negative), but the latest Kodak price list does NOT list them available with 16mm silt/perf specs!

All of the above have a equivalent ISO of somewhere between 6 and 12, as I seem to recall.

It should be a 5000 series if cut and perforated for 16mm; i.e., replace the first digit of the stock with a "5" = 5324, etc...

I would suggest you call a working motion picture lab, like Colorlab in Maryland and ask if you can buy a short end of one of the above stocks. Otherwise, minimum orders for non-listed Kodak stocks tend to start at 250K feet.

FFP didn't have what I was looking for, but they did have some 16mm IR film -- ISO 200, double perf, negative -- so I got some of that instead!!!

Positive print stock is always a good entry for the experienced as well as the beginner. Labs have print film in stock. Non-sensitised but of fine graininess and not expensive, developed in three to four minutes, you can see what a lens is delivering, how accurately you focus, how lighting might be improved, whether the whole setup is worthwhile.

Print films are not made to a given exposure index, therefore batches vary in sensitivity. Generally they are around ISO 8 to 10.

I agree that slow stocks are missing. Manufacturers have let themselves carry away from the real/reel thing which is how 16-mm. cinematography had begun. FOMA BOHEMIA could make a Fomapan R 20. That would be most welcome.

A lot of people say that Fomapan 100 actually is a 50 ISO film, so this would get you under 100 ISO. If you then pull-process by one stop you should have 25 ISO.
What do you need a slow 16mm film for?

For filming in the snow, at the beach, everywhere where you have plenty of light, for a fine graininess, a smoother image, less depth of field at wider apertures, simply for a better quality than with high-speed stocks. I imagine slower films can be manufactured more cheaply because they take less ripening time.

I meant what the OP wants a slower film for - as he asked for a film below 100 ISO but then bought some IR film at 200 ISO.

嗯，我知道的其他胶片只有 Fomapan Cine 100，这是感光度最低的 16mm 带孔黑白负片，以及 Fujifilm HR，这是我所知道的感光度最低的 16mm 缩微胶片。如果要装进需要打孔的机器，比如 Rollei 16，打孔确实很麻烦。不过，我在 FPP 上见过一些感光度低于 100 的黑白负片，但我没试过，比如 FPP Sonic25 BW Negative。

我用的是Lucky 1021 16mm双孔ISO160，很便宜但是颗粒比较大，一般用在minicord上。
