Has anyone tested it? Do they make 400ft rolls?

[Sebastian Bock]

It is probably the same emulsion as the 2023 released still film, so you'll find a couple of tests and images online.

Since it is an orthochromatic film, it is less sensitive to the red spectrum and it has its highest sensitivty at the green wavelenghts. Here is the datasheet: FOMAPAN 400 (fomaobchod.cz)

It is pobably not an "all purpose" film but it is really good news, to have a new tool in the toolbox...

As far as I know, Foma sells 400ft rolls only as special order. Regularly they sell the motion picture stocks only on daylight spools.

Bumping this thread to see if anyone has done any tests with the Cine Ortho 400?

I bought a roll to shoot some tests (which I will share here). Any tips on exposure or development? 

[Sebastian Bock]

In the German narrow gauge film forum users reported successful negative development with D96 for 7 minutes.

Reversal development was done by a user with ORWO A71 developer + KSCN, diluted 1+1 at 22 degrees for 3.5 minutes with pleasing results. Under tungsten light the sensitivity was more towards 320 iso, under daylight 800 iso.

I contacted Foma and they said they would begin selling their cine negative films in 400ft rolls sometime this year as a regular product, not requiring bulk orders.

I see B&H carries the 100asa version in 400ft, which I will get and test..I wonder if  the  400 ASA will be offered in the US .. Good to know that they are making 400ft rolls.
