In addition to the unveiling of the Sony A1 II, the Sony FE 28-70mm F2 GM large aperture standard zoom G Master lens has also been announced. This new G Master lens is the first to feature a constant F2 aperture, resulting in less noise and crisp images, larger and smoother bokeh, and a compact design allowing for easy travel and run-and-gun shooting. Let’s take a deeper dive into the features!

Sony’s G Master series of E-mount lenses are well regarded for their high resolution, clarity, and bokeh. They offer a wide range of focal lengths, including prime and zoom lens options. Many of the G Master lenses are compact and light to carry and use.

A closer look at the Sony FE 28-70mm F2 GM lens

The new Sony FE 28-70mm F2 GM lens is fast and compact, making it easy to carry and shoot. The F2 maximum aperture delivers sharp images with minimal aberration, while the smooth, cinematic bokeh opens up opportunities for creative expression. The 28-70mm zoom range also cuts down on the need to carry and swap out prime lenses.

Thanks to its fast F2 aperture, there isn’t as much of a need to boost ISO or slow the shutter, resulting in less noise and blur. Sony says the new FE 28-70mm F2 GM lens has the performance of a prime but the convenience of a zoom.

While the new Sony FE 28-70mm F2 GM lens is similar to the compact FE 24-70mm F2.8 GM II zoom introduced in April 2022, it is faster at a constant F2. This prevents the need to boost ISO, helping to keep image noise down.

The Sony FE 28-70mm F2 GM lens features excellent corner-to-corner resolution at F2, the G Master line’s famous bokeh, suppressed aberration, minimal flare and ghosting while retaining clear images, and high resolution similar to prime lenses.
