Ideally, it should be a flat field. In the real world, my understanding is that it's a bit of both. The field isn't a perfect section from a sphere, nor is it perfectly flat. Most macro lenses are designated as being corrected for flat fields. In the real world when not using macro, the only time this usually matters is when you first buy a lens. The flatter the field, the better it will perform with the newspaper-taped-to-a-brick-wall-compulsary-pictures. :) -- Eric http://canid.com/
