For some time, I've contemplated the Hartblei and Arsat tilt-shift lens for some projects of mine. I have the Nikon 35mm PC/Shift f/2.8, but it's not quite managed what I'm interested in achieving. I think the tilt function is very much called for. Sadly, I don't think that I can persuade Bjørn Rørslett to part with his home-made 28mm tilt-shift lens (A Dream Lens Come True). Now, I know that Canon makes a 24mm T/S, but, insofar as I'm aware, there are some serious physical barriers to altering the mount to Nikon standard, not to mention that the lens costs well north of US$1K before any alterations. I missed purchasing a Zuiko 24mm f/3.5 shift lens re-mounted for Nikon a bit back at a local store (stupid me !!!), but in thinking about this, I believe that I want the tilt function as well. So. Has anyone here being using the Arsat or Hartblei tilt/shift lenses and could they share their impressions/reactions/experience with these lenses ? I've done the usual due dilgence Google seaches and read the reviews, but in all truth, I'd like to be able to get comments from people that I know (and, believe it or not, actually trust). TIA. John P. P.S. Of course, if Bjørn still reads this forum and wants to sell his delightfully interesting lens, I'd buy that one !!!
