It's got the same ajustment screw and grind range as any other zass. I'd say a lot of people make the assumption that the "Turkish" mill is finer, perhaps that's why Zass themselves call it a Mokka.
If you look at their web site
http://www.zassenhaus.com/ it's interesting that the turkish is in the Kaffeemühlen section not the Espressomühlen section. Does this mean they don't think it's up to grinding for espresso?
Plus points:
Small and great for travelling
Can grind fine
Looks good
Minus points:
The finer you grind the longer it takes (same for all manual grinders)
Zass grinder settings can tend to wander a bit
Leaves your hands smelling of brass (and you wondering if it does the same for your coffee)
Mine is inconsistant
