16-85 lens not shown in EXIF data K-5

I just obtained the 16-85 to replace the good old Sigma 17-70 on the K-5. The much smoother autofocus is the most striking difference, corner sharpness and minimal CA at 16 mm the next one.

However it strikes me that the 16-85 lens seems not to be recognized as such by the system; DCU4 says 'lens unknown', exif viewers say the same. The most extensive information I could see was "Unknown (8 200)". I have the newest versions of firmware and DCU4. Is the lens so very new that the firm-and software is not yet updated for it ? Or are the K-5 and DCU4 already considered outdated by Pentax ?

The automatic correction for CA and distortion works fine, also in DCU4. Just it strikes me that automatic marginal illumination correction is not possible.
