Since the camera is thought to be directed at advanced amatorial users maybe Pentax guessed they could use a slightly slower motor drive and a less performing shutter without losing too many possible customers at a cost advantage. I have a Z1-p and I know I never used the continuous mode for the motor and never used speeds faster than 1/2000. As I shoot soome macro the max. synch time does weigh more in my personal priorities so 1/180 while not unacceptable would have been a minus in the camera evaluation.

Re: Why the slower shutter and motordrive on the MZ-S?
Assuming the same nominal voltage (6v : 2xCR2, 2xD123, 4xAA) the more current the more power (W=VxI). Bigger batteries (for a given chemistry) can supply more current for a longer time than a small battery. This limits the speed of the AF and film advance motor. Current is also a factor in shutter speeds. The blades have to be accelerated harder and move faster for a high sync speed. With high fps rates the mirro also has to be moved faster. The faster shutter blades and mirror has more inherent vibration, which becomes more apperent with smaller, lighter bodies. I don't think anyone is selling a body that weighs as little as the MZ-S with 1/250 sync, 1/8000 shutter and 4 fps drive. From: "Robert Soames Wetmore" <[EMAIL PROTECTED]> Subject: Why the slower shutter and motordrive on the MZ-S? Is this true - that the small bateries were the main thing governing the shutter/motordrive specs? I'm not trying to pick a fight - I honestly don't know enough about it. Is a faster shutter also larger? I assume a faster motor is going to be a bit larger - or is it really not that much with the advances in microelectronics? I'm just wondering how small the MZ-S could still have been if it had had, say, 1/8000 max. shutter, 4 FPS motordrive, and used maybe 2 CR123s or a 2CR5 or whatever.
