Built quality and reliability wise, the whole MZ/ZX series are identical except the MZ-S (and the phantom MZ-1 too
). From what I can remember (but I could be wrong), the MZ-10 cannot control the aperture manually but otherwise a very quiet and nice camera to use. AF works fine too. But as with any MZ models, flash not pop-up and mirror lock-up are rather common because of weak plastic parts. The improved replacement parts are very cheap but the labour is not. So I have mixed feeling on recommending any of them unless you know how to repair.
