Light and ideally balanced telephoto 300 mm F2.8
The SEL300F28GM is the lightest large-aperture telephoto prime lens in its class, delivering outstanding optical performance and rendering plus astonishingly fast, precise AF in a versatile lens that weighs just 51.9 oz (1,470 g). (Excluding tripod mount) The lens has been designed so that its weight is not concentrated near the front, in order to give the best balance. This can minimize stress and fatigue during long handheld shooting sessions. 

Breathtaking G Master resolution
An innovative optical design including three Super ED (extra-low dispersion) glass elements and one ED glass element effectively subdues axial chromatic aberration as well as lateral chromatic aberration. Outstanding resolution and contrast are maintained right out to the image edges, which also allows for more flexible cropping and editing.

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 optimize 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 maximizes 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 lightest at 51.9 oz (1,470 g 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 optimizes 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 resistance plus high durability
A dust- and moisture-resistant design provides extra reliability for outdoor use in challenging conditions. The use of a durable magnesium alloy for internal components and other refinements maximizes durability while reducing weight.
