The G Master series incorporates the most advanced technology currently available, further enhancing the highly acclaimed performance of Sony's G lenses. This model combines G Lens bokeh with higher resolution than ever before in an outstanding portrait lens that fully exploits the performance potential of today's and tomorrow's high-resolution camera bodies. The excellent resolution reproduces the subject with impressive dimensionality even at the maximum aperture of F1.4. The gradual, beautiful bokeh creates an artistic, blurry background with natural colors and highlights. This rare combination, partly due to the new XA technology, opens up new design possibilities. Image errors can affect both resolution and bokeh. Three ED (Extra-low Dispersion) glass elements contribute significantly to the excellent optical performance of this lens by keeping axial aberrations in check while optimizing the clarity and natural effect of its stunning bokeh. In addition to the usual rotation sensor, a second sensor detects the position of the focusing unit. This 2-sensor system enables the extremely precise focusing required to fully exploit the potential of modern high-resolution camera bodies. An SSM drive (Super Sonic wave Motor) provides the required power and speed. Sony's circular aperture design typically uses up to 9 blades, but this is the first α lens with an 11-blade aperture that delivers a wonderfully smooth bokeh with natural-looking highlights. The modern nano coating of the lens has a precisely defined nanostructure that effectively suppresses reflections, reducing light reflections and ghosting, resulting in sharper, more contrasting images and better overall image quality. In addition to the usual sealant against dust and moisture, a sealant has been applied to the lens-camera interface, allowing you to take pictures without worries even under difficult conditions. Easily take pictures in light rain or wind.
