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.
Efke and Adox are brands, Fotokemika is a manufacturer (i.e. they coat film).
The brand Efke belongs to Fotokemika and Adox to Fotoimpex. Some, but not all Adox film is coated by Fotokemika and may be available as Efke too. Others were coated by Ilford (afaik) or are coated by Agfa Gevaert (NOT Agfa Photo, who produced APX and MCC and is dead).

This is great news for IR lovers. Along with the 3 films Robert has mentioned above, Ilford's SFX is also back.

The Efke 820 will be coming out in 8x10 and 4x5, according to someone at Freestyle, probably within a few weeks. I already have 5 rolls of 120 that I purchased through Freestyle.
That 850 film should be interesting -- would you expect to see much of a difference between it and the 820?
