Get Canon 135mm f/4L at B&H Photo.
This scene shows the use of a very strong tilt of 5° along with maximum fall (downward shift). Thus the image circle is shown at its most extreme area (in the immediate foreground).
The use of tilt here also demonstrates the ability to make a sharp plane from very close to infinity even as here with a 135mm lens.
As to fall (downward shift), I wanted maximum foreground rather than a chunk of rocky hillside, thus the maximum fall of 12mm.
Includes images at sizes up to full camera resolution from f/4 through f/16, and crops also.
Below, consider that this was shot at f/4 with a 135mm lens. Think about how shallow depth of field is at 135mm—this kind of shot is impossible without tilt.
