Full aperture metering is enabled for all KA-mount and later series lenses, that is, those with an "A" position on the aperture ring. (Pentax lens series "Pentax-A", "Pentax-F", "Pentax-FA", as well as the current Pentax-DA and Pentax-D-FA models.) Older, plain K-mount lenses are supported with semi-automated stop- down metering in Manual exposure mode. Pentax in-body IS supports using older lenses by users inputting the focal length manually. > Is it any better for those lenses than other cameras I might > consider -- Oly e510 for in-body anti-shake in a smaller > package or a 5D for those big pixels -- with an adapter? Pentax mount lenses adapted to 4/3 System or EOS mount must be operated with manual iris, stopped down manually for metering and exposure. Olympus' in-body IS only supports native 4/3 System lenses, there is no way to input a focal length manually which is needed to operate the stabilization system. Adapted lenses work just as they do for Canon EOS: manual iris, stopped down manually for metering and exposure. > What about for screw mount Pentax lenses? My guess is > none of the adapters give full aperature metering for those. Pentax screw mount lenses can be adapted to all of the above and work the same way as adapted lenses on Canon and Olympus: manually stopped down for metering and exposure.
