Efke/Adox Films: optimal sensibility.

Hello,

First please excuse my bad english if there is any mistake... I am french.

I write here because I'm really interested in Efke/Adox films, but I have a big question:

what are the optimal sensibilities of this Films? On the french pages of your site, you say that is twice the sensibility writen on the box. But I find this really curious... and I read in an old page of the english website of fotoimpex that the kb25 was optimal at 20 Asa... So I would like to know all you can tell me about Efke films and their sensibilities... <img src='http://forum.fotoimpex.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt=':D' />

by the way, where can I find the developing time of these films in Tetenal Neofin Blau? (perhaps on the packing of these products? <img src='http://forum.fotoimpex.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt=':D' /> )

Thank you very much. <img src='http://forum.fotoimpex.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt=':)' />
