This G Master 35mm, full frame, standard zoom lens is a great choice for professional photographers who require the best optical performance possible. The SEL2470GM utilizes newly developed XA technology to reduce chromatic aberration and provide softly dissolving bokeh without sacrificing image resolution at any point in the zoom or aperture range.
In order to further improve image quality, the SEL2470GM features Sony’s Nano AR coating that reduces the amount of light that’s reflected by the lens and helps reduce lens flare and image ghosting. This lens also has a constant F2.8 maximum aperture that allows you to more easily maintain exposure settings while changing the zoom range.
Constant F2.8 Maximum Aperture: Shooting in low-light situations is always challenging, but the SEL2470GM‘s constant F2.8 maximum aperture ensures that you’ll get great looking pictures in any light and at any zoom range. You won’t have to worry about readjusting exposure settings, either, as this lens maintains its settings as you zoom in and out. Since you won’t have to readjust exposure settings, you also won’t have to deal with slower shutter speeds in low light either.
