| Efke, (most) Adox and the Maco IR820C, all produced by Fotokemika (nova) in Croatia.
This Efke IR820C film is produced with a slightly different organic sensitivity dye because the old one (from Maco) was not available anymore.
So more or less the same.
In the mean time Rollei/Maco has produced a new IR 850nm film, based on APX 100 (Agfa) emulsion (also iso 100). This new extended I.R. film should be available in about 2 months.
The Rollei IR-820/400 film (iso 400) is the other Rollei IR film alternative. But the sensitivity of this film is going down fast over 750nm. This film must be used with a 695nm or 715nm "black" I.R. filter to get the 'wood' effect.
