Beautiful bokeh brings subjects to the fore

The gorgeous and creamy bokeh allows the use of narrow depth of field to make subjects stand out from the background. In addition to Super ED (extra-low dispersion) and ED elements in a new optical design that effectively suppresses colour bleeding, each lens is individually calibrated during manufacture to optimise bokeh quality. An 11-blade circular aperture mechanism contributes to smooth ball bokeh.

Fast, precise AF brings out the full potential of advanced bodies

The lens maximises the speed potential of high-performance camera bodies, making it easy to capture important moments in dynamic sports action or fast-moving wildlife scenes. Two XD (extreme dynamic) Linear Motors with high thrust efficiency and an advanced control algorithm have been specially fine-tuned for fast response to control signals. Additionally, AF tracking speed and precision are maintained even when shooting continuous bursts.

The lightest² at 1 470 grams (51.9 oz.)³ and ideally balanced

An optical design that includes Super ED (extra-low dispersion) glass elements has reduced the subjective weight by using fewer elements positioned near the front of the lens, so that the weight of the lens is not concentrated at the front. This optimises balance and reduces moment of inertia which is felt as resistance to rotation, allowing precise, agile lens movement and panning while shooting.

Dust and moisture resistance⁴ plus high durability

A dust and moisture resistant design⁴ provides extra reliability for outdoor use in challenging conditions. The use of a durable magnesium alloy for internal components and other refinements maximises durability while reducing weight.
