It's a pity that Pentax seemed to be late on everything in recent history. It would be nice if the MZ-1 was released at the time of the MZ-3 and forgo the MZ-S altogether. The MZ-S hit the market too late and too expensive.
But, IMNSHO, the MZ-S was/is a wonderful camera. In fact, it's the only 35mm having survived in my stable.
