"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."

Thanks for that info! Never too old to learn <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='' />.

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.

Actually, close focusing robs one of as much light as extension tubes do, at the same magnification anyway, as this is directly related to magnification, and nothing else. This is even true with close-up lenses, although it isn't as obvious with those, due to the shortening of the FL they cause for the system as a whole <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='' />.



The amount of light you lose is exactly the same at the same magnification, whatever lens you use.



Kind regards, Wim
