Linear -- it's the standard Pentax centerweighted gallium meter in
the prism, which doesn't require the circular polarizer. Though it
has TTL flash metering, it doesn't have the semi-silvered spot on the
mirror that requires light to pass through the mirror to a meter cell
(or an autofocus sensor) when the mirror is down (like the LX or
autofocus cameras).
