FE 24-70mm F2.8 GM (SEL2470GM), 7R II, 1/400 sec., F6.3, ISO400 A new standard for a high-resolution future Resolution can give meaning to an image Unlocking fine details that are the essence of beauty 50 line pairs per millimeter is a baseline for G Master™ design Delivering breathtaking detail wherever you look 100% image display Resolution that's ahead of evolution What are the requirements for interchangeable lenses that will remain relevant in the face of continually evolving camera body performance? As a company that is largely driving that evolution, Sony has the answers. The G Master series elevates resolution to unprecedented heights thanks to new technology specifically developed to accommodate the more exacting tolerances required. Sony has unreservedly applied the most advanced optical technology available in innovative lens elements, optical path design, simulation, testing, and calibration, achieving image detail and sharpness that reveal the essence of every scene and subject.

Refined simulation software has also made a vital contribution, making it possible to predict and eliminate potential problems throughout the design and manufacturing processes and thereby Spatial frequency R T 10 line pairs / mm 30 line pairs / mm 50 line pairs / mm R: Radial values T: Tangential values realize the highest design standards without compromise. Lens coatings can be included in the simulation, allowing designers to accurately predict how they will affect ghosting and color in the final product. That in turn has made it possible to use Sony's Nano AR Coating technology in the most effective way. Industry-leading actuator technology inherited from professional Sony movie equipment contributes too, providing the focusing precision needed to fully realize each lens's resolution potential. 50 lp/mm: Spectacular resolution wide open It is not easy to achieve spatial frequency of 50 lines pairs per millimeter at a lens's widest aperture, but that is Sony's baseline for G Master design. Unprecedented resolution and other demanding design parameters yield outstanding reproduction of the most detailed subjects and scenes with superior contrast throughout every frame. G Master resolution is simply the highest in its class. Spatial frequency R T 10 line pairs / mm 30 line pairs / mm 50 line pairs / mm R: Radial values T: Tangential values 07 Contrast (%)
