Well Randy, nobody has yet answered your question, and I await with bated breath, as I have the export version of that lens, and it is no different functionally or physically to the apparently more desirable Japanese home market version. On occasion I have used it on my Df, and noticed some initial awkwardness in getting fingers to operate the aperture ring. The F/Z adaptor may make it easier to locate the ring; I don't know, as I've not yet seen/operated this combination of camera, adaptor and lens, obviously. Just as obviously, it appears to me that this combination would be perfect. In addition to bathed breath, I await with fingers crossed!(Birna take note, please, pretty pink please!?)
