Does anyone here have user experience with the TS-E 17 mm tilt-shift lens in landscape and nature photography? Given the large depth of focus at 17 mm, I would have to be very close to the foreground to take advantage of tilt. I calculate that, without tilt and at f=11, the hyperfocal distance on an EOS 5Dii is from about 1.5 ft to infinity. I can see some potential interesting shots, but how useful is it in practice? I do have the 14 mm and the 45 and 90 TS-E lenses and use all these lenses a fair bit. I don't do enough architecture to justify the expense of the TS-E 17 mm. Thanks for your comments.
