There is no getting around it,
traditional
tilt/shift lenses are expensive, with the cheapest Arsat model coming
in around $600 and Nikon's T/S lenses at $2,200 each. Because the image
circle of Nikon Pre-AI, AI, and AI-S lenses is large enough to cover
35mm film, they can be used as a tilt lens via an adapter to the Sony
NEX E Mount or Micro 4/3 cameras. If you put "Nikon to NEX tilt
adapter" into the ebay
search box plenty of results come up.
I bought one of the $50 variety. Rotating a ring on the adapter sets
the degree of tilt, while the whole thing rotates 360 degrees allowing
the tilt to be set to any angle. Unfortunately the rotating ring
doesn't have enough tension and is too easy to change, while the
adjustment for tilt is hard to keep at the exact degree you want. The
degree marking is just a sticker that comes off
only too soon. To add to the downsides, it does not allow any
lens with a hard focus infinity stop to focus to infinity. It is also
not usable with G lenses. That creates quite the conundrum as most
Pre-AI/AI/AI-S lenses have a hard focus infinity stop. No free lunch
here. It's a tilt adapter and it does tilt, but with poor construction
and handling. Since it can't focus to infinity it's not the end all be
all Nikon AI to NEX adapter.
