Fluorite Lenses-The Ultimate High-Performance Lenses

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.

DO (Diffractive Optics) Lens (CG)

DO (diffractive optics) lens elements enable telephoto lenses to be lighter and more compact while maintaining a high level of performance. Canon succeeded in creating the innovative DO lenses by bonding a precise diffraction grating to the surface of a glass lens. This video introduces the mechanics of DO lenses, highlighting the construction of dual- and triple-layer DO lenses.
