New XD (extreme dynamic) Linear Motors deliver higher thrust than conventional types, achieving up to a 5x improvement in moving-subject tracking performance with current and future camera bodies. Two of these new motors and newly developed algorithms quietly drive the lens’s large focus lens group faster and more precisely than ever before. The full-speed performance of advanced camera bodies can be applied to capturing dynamic sports or wildlife subjects.

Stunning G Master resolution and bokeh

Extremely high design standards ensure outstanding resolution right out to the image edges. Three fluorite elements minimize chromatic aberration. Spherical aberration is carefully controlled during design and manufacture to achieve the highest possible bokeh quality. Optional high-performance 1.4x and 2.0x tele-converters are supported, providing outstanding resolution and contrast even at 800mm.

Durability and reliability for challenging conditions

Dust- and moisture-resistant design provides the reliability needed for outdoor use in harsh conditions. A durable magnesium alloy used for the lens barrel exterior, tripod mount, and interior barrel components achieves tough durability while minimizing overall weight. The front lens element features a fluorine coating that helps to keep it clean while making it easier to wipe dirt and fingerprints away.
