Yes, I understand that the ADOX PAN 400 emulsion will be different than APX 400. However, as long as your product development started from the last (2003) incarnation of APX 400, I'm confident that times in Rodinal 1+50 will be long, if not exactly 30 minutes. "Long" is all I need to be a happy consumer of the new film!
