If a 24 mm lens has an 84 deg. angle of view, and if you used maximum shift of
10mm on the 25/shift, what would be the equivalent rectilinear wide angle to
take in the same undistorted image? (This is difficult to ask clearly).
Would a 14mm or 15mm allow me to to use just the top half of the photo to keep
rectilinearity and would this allow me to get in more of the building than the
24 shift?
In other words, would this be a good lens to take on a slot canyon trip?
Thanks.
