Is it really different thickness?
First time ive heard this!
What would the reasons be for this I wonder?
S8 is the same as 35mm, as they often slit down unperforated 35mm into s8 at pro8mm and Wittner-Cinetec.
Where did you hear this please?
I doubt they will, but I expect that Kodak hope they will beat Ferrania.Who thinks Kodak will have E6 film on the shelves before Ferrania?
It's not even going to be close, assuming Fearrania hit their summer target date.I doubt they will, but I expect that Kodak hope they will beat Ferrania.
According to both companies roadmaps, Ferrania will be first

It's in my local camera storeI haven't seen E-6 film on a shelf in 15 years

Same here, and they dont even process the stuff!It's in my local camera store
Yes, exactly, my local store stopped processing E-6 recently. It's a shame since they used to do a really good job!Same here, and they dont even process the stuff!
The fact that some people re-purpose one stock for use in a different format doesn't mean that the two different formats are usually on the same support.Is it really different thickness?

I wouldn't be surprised if 35mm motion picture film and Super 8 motion picture film are on the same support, but I do know that 135 format still film can be found on different supports.
And 135, 120 and large format (not to mention motion picture) cameras have distinctly different requirements for film rigidity and flatness, due to the ways that films are held and transported, so it makes total sense that the support for those films would differ.
There's still plenty around here in London.I haven't seen E-6 film on a shelf in 15 years
I expect for Ferrania E-6 to arrive in my mailbox before Ektachrome.
Actually, it can be thinner - don't forget about the role that backing paper plays.So I assume 120 needs to be alot thicker to keep it from curling in the camera i expect?
Very interesting...1. 35 mm is on 5 mil support.
2. 120 is on 4 mil support
3. Sheet films are on 7 mil support.
Movie film cameras and projectors and roller transport processors can be real tough on movie film.Very interesting...
So what are the detriments of using 4 mil support for 35mm?
Tearing of sprocket holes is not uncommon in mo pic equipment and then jamming.

Movie Negative is often the 5 mil Acetate. they use Bell and Howell Perfs (BH1866) which are slightly smaller than the Kodak Standard (KS1870) perfs we see on still film. Back in the 1950-1960 era, Movie print film, that you might see projected in a theatre, gradually went to Polyester (ESTAR) and started getting slightly thinner, so that it maintained the same stiffness as the Older Acetate stuff. Still with the Ks1870 perfs like you see on still film.
The KS perfs are actually slightly stronger than the BH perfs, as the radius of the corners is larger. BUT the Negative only has to be transported at 24 Frames a second intermittently Once when shot, and all subsequent stages it is run continuously and smoothly.
The projection print has to Move in something like 0.007 seconds from one frame to another (18mm) (1/6 of the 24th of a second with the typical 3 blade shutter ) that it gets the limelight) so it needs the stronger perfs.
Yes thats correct, means i can bulk load more of it on my rolls toowith the same base, it would not be as strong. More chance to damage the perforations. Also one must be careful as some cameras will not be able to hold a thiner film flat. Some Poly film is in fact thinner, that Aviphot 200 E6 stuff for example.
I understand Ilford cuts both Delta 3200 135 and 120 formats from the same master roll with 0,125mm/5mil support.1. 35 mm is on 5 mil support.
2. 120 is on 4 mil support
3. Sheet films are on 7 mil support.
These are all approximate thicknesses. It varies between manufacurers. The sheet films are thicker to prevent buckling and facilitate even processing and the 120 and 220 films are thinner to allow for the paper base in the first case, and the longer length in the second.
