Fluorite is the ideal mineral for correcting chromatic aberration. However, no naturally occurring fluorite can meet all the requirements for a camera lens. Based on our belief in making use of its own abilities to create whatever is necessary, Canon overcame the numerous barriers that stood before us to successfully realize the mass production of fluorite lenses. Canon is now the only manufacturer to incorporate fluorite in its auto-focus lenses for SLR cameras.
