Hi Everyone,

I need some clarification regarding the MZ-M. I've read many reviews on this camera. They say that it doesn't have TTL flash metering.

The US Pentax website says, "Metering system: TTL open-aperture 2-segment metering."

Since the camera meters through the lens, why can't it meter flash TTL? Can anyone kindly explain the difference? Thanks.

For setting exposure - the camera meters through through the lens with the mirror down. The light sensors surround the pentaprism/pentamirror.

To quench the flash when sufficient output has been generated - TTL Flash metering is done with the mirror up. The sensor is inside the mirror box and measures the light bouncing back from the film.

Two entirely different metering requirements and methods.

You can view a pdf of the MZ-M manual here:http://www.butkus.org/chinon/pentax/pentax_mz-m/pentax_mz-m.htm

The section regarding the use dedicated flash confirms that TTL flash is not available.
Die my dear doctor, that's the last thing I shall do!
