The Sony FE 28-70mm f3.5-5.6 OSS is a versatile standard zoom lens designed for Sony's full-frame E-mount mirrorless cameras. This compact and lightweight lens covers the wide to short telephoto range, making it ideal for everyday photography, travel, and general purpose shooting. Featuring optical image stabilisation for sharp handheld shots, quick and silent autofocus via a linear stepping motor, and internal focusing that enables use with polarising filters, this lens delivers reliable performance across a wide range of shooting scenarios. The optical design incorporates three aspherical elements and one ED (extra-low dispersion) element to minimise distortion and chromatic aberration, while the seven-blade diaphragm produces smooth, natural bokeh. Its compact 73 x 83mm barrel and lightweight 295g construction make it an excellent travel companion.
