I have the older D version of this lens (not that I need it, it's a huge indulgence), and although the instructions for this lens give ordinary depth of field charts, there is nothing comparable for tilt. I think the problem is that the variations of distance, tilt, and subject angle, not to mention useful depth of field, are so great that it's nearly impossible to quantify. It certainly does work, in varying degrees, and it's a grand lens, but I don't know of any charts for the tilt. I don't know about the newer one, but the old one goes to an astounding F45, which of course introduces a lot of diffraction, but gives some unusual depth of field.
Is there any place available to you for renting one?
I did a very quick and dirty comparison with mine. This lens is a little difficult to use, heavy and prone to vibration, and it's not really ideal on a D3200 either. By comparison, on something like an F4, it sings as a hand held macro lens. Ignore the color shifts, as I do not have a proper TTL flash. Obviously, there is also no middle ground shown here, but as you can see, the change is pretty dramatic at F2.8 (effectively more like 4), and the depth of field considerable at F45 with or without the tilt. Diffraction loss occurs, but you can still see pretty good detail.
e.t.a. apologies, forgot to say what is shown. First pair is straight at F2.8 nominal straight on and shifted. Second pair is Same tripod position, 45 nominal straight and shifted, moved to center on the same point (the hyphen below the filled-in 0). I keep mixing things up, so if you just read my first edit, please note second edit change....and further edit to add, with apologies because I actually do have some post accident brain damage that makes me mix up words! When I said "shifted" I of course meant "tilted." Duh.
