I'll tell you this though, if I didn't already have more than enough original APX100 to hold me over, I'd be on the hunt for the original APX100 Lupus has been offering. That being said, I do think there is still room for ADOX Pan 400 as both APX100 and APX400 are not duplicated by any existing 400 speed film. None of the APX line is and the closest I've seen is TMY2 giving similar mid-tone tonality, but APX has always had it's own thing going on due to how they tuned the sensitometry.
