No, I think that means that the *design* of the lens incorporates a
larger image circle covering the same field of view as an 18mm lens.
But that doesn't mean you can capture that full field on a 35mm frame.
The size of the good quality image circle is larger than 24mm to
accommodate the edge of the field of a shifted lens.
