Kowa's 3-CAM Design
Kowa's innovative 3-CAM design utilizes guide pins to minimize contact points thus significantly reducing friction and torque for a higher optical performance, longer lifetime and increased durability. The 3-CAM design is more robust and solves the problem of de-centering due to its guided pin design, in addition to the decreased internal reflection and reduced need for grease on the focus and zoom mechanisms.

Kowa's Bearing CAM Design
To support the 3-CAM design, Kowa's Bearing CAM development is especially important for long range zoom lenses. To support the weight and larger diameter, Kowa's Bearing CAM focus system uses dozens of ball bearings to absorb extra pressure while maintaining a smooth rotation.
