I've read the thread and don't remember if someone mentioned that airbrush is
spraying tool. Why would to expect the lines from its performance ? The "line" that produced by the airbrush is just a series of dots, it's never line like one produced by the pencil or the pen. One would use frisket or some other things to get very narrow line, and for this purpose (with added film or smth) many ABs would do. Or we use scratching and erasing tools for getting some types of lines, dots etc, that airbrush can never produce. So, why to expect lines from 0,07 mm nozzle, if in any case we have the airbrush with dotted pigment pattern? We'd only have more narrow series of finely sprayed dots.
It would be great if someone long ago would not call small spraying tool "air brush". If it would be called fine air sprayer (whatever), no one would expect brush (line) performance from this tool. Just spraying would be in mind. What lines?
One very reasonable thought has been said, that one thing that normally would go through this nozzle size is the ink. I don't think I'd use use candies for the detail work this AB is aimed to use. And painting the ''lines" with the candies.., seriously?
I need pigments.
Besides, in the post right above is well said about the experience and abilities of one using the airbrush,

Honestly, I'm not a big fan of Olympos 0,18mm nozzle (Iwata 0,18mm is larger, have no idea whose nozzle is real 0,18mm), though in some cases it's great. But even this nozzle requires some headaches with getting proper reduction for normal work. Something says to me that I couldn't use 0,07mm with my paints. This size even makes me smile. 0,01 or smth like that
The AB in the first video seems to be identical to Olympos MP-200 A or B model with three line Olympos micron "L" head, I'm not talking about the back side. Only some modifications were done to that AB body and after it was replated. Back side is of no importance for spraying, it can only give some kind of smoother performance of the needle mechanism.
