Yes, I´ve got one. Ambigious:

PICTURES ARE VERY SHARP AND CLEAR, SUPERB CONTRAST AND TONES

but
- prone to reflections at the long end
- visible distortion
- heavy
- focusing and zooming ring exactly the same size and structure, so it´s easy to get confused a little bit
- tripod clamp not removable, thus always disturbing zooming. You can´t get from 70 to 180 in a single movement without changing your grip
- thanks to build in hood polarizing filters are hard to mount / dismount. Even to use them needs a special lenshood (heliopan tele hood i.e.).

Is a close focus distance of 1.7 meters sufficient for you at inddor shots?

If you want to use ist with an APO extender, consider that you will probably have to send both items to the CS. The extender has to be adjusted very fine in order to prevent the focus from getting lost while zooming. TV cameramen will know that. It´s nothing bad, professional TV cameras have the possibility / necessity to adjust the flange (in German called "Auflagemaß") after each changing of a lens.
In spite of that the picture quality remains outstanding, I can really recommend this combination. 5.6 / 140 - 360 is a very useable range.
