You are looking at the Sony FE 300mm f/2.8 GM OSS Lens, a remarkable piece of optical engineering that stands as the lightest large-aperture telephoto lens in its class. Weighing just 51.9 oz (1470 grams) without the tripod mount, this lens offers exceptional optical performance and rapid, precise autofocus, making it an ideal choice for photographers who demand versatility and agility in their equipment.Designed for optimal balance, the SEL300F28GM minimizes stress and fatigue during extended handheld shooting sessions. Its innovative optical design features three Super ED (extra-low dispersion) glass elements and one ED glass element, effectively reducing axial and lateral chromatic aberration. This ensures outstanding resolution and contrast across the entire frame, providing flexibility for cropping and editing.The lens delivers extraordinary resolution and stunning bokeh, thanks to its 11-blade circular aperture mechanism. Each lens is individually calibrated to optimize bokeh quality, allowing subjects to stand out beautifully against a soft, creamy background. The fast, precise autofocus system, powered by two high-thrust XD (extreme dynamic) Linear Motors and an advanced control algorithm, enhances the lens's ability to capture dynamic sports action and fast-moving wildlife with ease.Built-in Optical SteadyShot stabilization ensures sharp images even at telephoto focal lengths, with MODE 2 offering stabilization for panned shots and MODE 3 enhancing stability for unpredictable sports action. Sony's Nano AR Coating II minimizes reflections, flare, and ghosting, ensuring crisp, clear images even in challenging lighting conditions.The lens features a programmable function ring for direct access to power focus or frame size selection, and Full-time Direct Manual Focus (DMF) allows for immediate manual focus adjustments even in autofocus mode. The Linear Response MF ensures precise manual focus control, while four customizable focus hold buttons and a focus range limiter switch provide additional flexibility.Supporting rear-mounted drop-in filters, the SEL300F28GM is compatible with standard 40.5 mm diameter filters, including Sony's VF-DCPL1 circular polarizer. The lens maintains high AF tracking performance even with optional 1.4x and 2.0x teleconverters.Built for reliability, the lens features a dust and moisture-resistant design with a durable magnesium alloy construction. A fluorine coating on the front element repels water and oil, making it easy to clean. The lens comes with an ALC-SH175 lens hood made from high-strength engineering plastic, a padded soft case for protection, and a lens strap for convenience.This bundle includes essential accessories such as a lens wrap, lens pen cleaner, rain cover, lens cap tether, and cleaning cloth, ensuring your lens remains in pristine condition and ready for any photographic adventure..
