That´s not true, the angle of view gets smaller!
The total angle of view of the lens, of course, is constant and
comparable to an 24mm lens for the 35mm shift and to an 18mm lens for
the 24mm shift.
The camera sees only a part of the total angle of view, because the
image circle the lens projects is cropped by the film window in the
camera. So without shift, effective angle of view is comparable to
the one of an ordinary lens of his focal length.
And why does the angle of view gets smaller with shifting the lens?
Imagine an extrem shifted lens, so the camera looks through the film
window like you would look through an window at an accute angle. As
more accute the angle of view the window converts into small slit to
look through.
Of course the amount of shift is that small, not much change of
angle of view happens.

There was once an comparision test of shift lenses in ColorFoto. The
35mm Olympus shift proved there to be one of the better lenses.

The 100mm/2.8 will not disapoint you.
