Today Canon announced it has reached the lofty production milestone of thirty million interchangeable EF (or electro-focus) lenses. A feat that took less than twenty years since the launch of Canon’s EOS camera system and the EF lens mount.

In a press release Canon stated:

“The EF lens mount revolutionised SLR photography in 1987 by replacing mechanical links between camera and lens with electronic contacts and providing for an internal auto focus motor. Even with continued development and evolution of focus systems, Image Stabilizer technologies, lens element materials science, weather sealing and design, the EF mount remains consistent. Every EF lens is compatible with every EOS camera ever produced, including all new digital EOS cameras.”

I know it’s PR fluff, but look at the picture! It’s purdy. (Admire it for the lighting, glass is a beast to photograph.)
