Aszongya a Photographyreview:

"Heralded as the new flagship model of its popular ZX/MZ
SLR series lineup, the MZ-S features a user-friendly “Hyper Operation”
system, a new six-point AF system, a top shutter speed of 1/6000
second, an on-the-film data recording function, and a dramatically
designed metal body. "
