I believe that is a fair prediction based on what I've seen with my cameras. Pentax manuals do state that using the "A" setting on a body that doesn't support it will result in incorrect metering.
As the aperture ring is closed down to "A", the aperture simulator tab on the mount continues to go past f/22, yet the aperture gets no smaller. This was observed by me on an A50/2. --- John Francis <[EMAIL PROTECTED]> wrote: > > I believe lenses set on "A" will behave as if set to > f22 (although > the metering circuitry may very well believe they're > set to f32). > I'd guess lenses without aperture rings will behave > the same way, > and stop all the way down, rather than remaining > wide open. > > __________________________________________________ Do You Yahoo!?
