It is at maximum aperture for focusing/framing as it has the standard auto-iris diaphragm. However, at exposure time it will always stop down to minimum aperture because the aperture regulator is dependent upon the body to set a desired f/number. The LX does not have the appropriate iris control mechanism for a more lens used in the "A" position, which is how the DA lenses appear to a body.
