I assume you know that only the new version of the Nikkor 85 PC has tilt? The old version only can do shift.[/quote]



Not so.

"Long awaited, my 85 mm f/2.8 tilt/shift Nikkor finally arrived yesterday."



"As delivered, the 85 PC has its shift and tilt movements orientated at right angles."



etc.

BTW, the TS-E 90 takes extension tubes extremely well (and extenders too), so the 1:3.4 is not all that limiting <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='' />. Unlike with the 24, this is not a retrofocus lens (actually a double Gauss variant), so any number of extension tubes will work <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='' />.[/quote]



Extension tubes can be mounted on most lenses - 85/2.8 PC included - however I don't like using them. They rob you of too much light. That's why the only extension tube I have is the 12mm one. I had a whole Kenko set but rarely used the longer tubes. That's also why I prefer to work with lenses that inherently have as big magnification ratio as possible.
