Little Bouquet uses only high quality Aspheric lenses. An aspheric lens design reduces or eliminates distortions. This is because, as the eye travels away from the center of the lens, the front curve changes, keeping the optics clear and crisp. All expensive camera lenses feature aspheric curves. Aspheric lenses also end up being thinner than conventional lenses. In an aspheric design, the lenses have flatter curves. This means lenses do not "bulge" out of the frame as much as regular lenses.
