The Sony FE 28-70mm F3.5-5.6 OSS is a full-frame (FE) variable maximum aperture standard zoom lens for Sony E-mount, announced by Sony on October 16, 2013.[1][2] It was the first kit lens for Sony's full-frame E-mount (FE) system,[3] and was released on the same day as the Sony α7 and Sony α7R. It is often bundled with various Sony E-mount full-frame mirrorless cameras, and is a less costly alternative to other standard zooms such as the Sony Carl Zeiss Vario-Tessar T* FE 24-70mm F4 ZA OSS.
Though designed for Sony's full frame E-mount cameras, the lens can be used on Sony's APS-C E-mount camera bodies, with an equivalent full-frame field-of-view of 42-105mm.
Construction
[edit]The lens has a weather resistant plastic construction with a matte-black finish and rubber zoom and focus rings. The barrel of the lens moves outward from the main lens body as it's zoomed in from 28mm to 70mm.
Optical properties
[edit]The Sony FE 28-70mm F3.5-5.6 OSS shows acceptable chromatic aberration[4] and good bokeh.[5] Corner sharpness becomes “acceptable” when the lens is stopped down to f/8.[4] Natively, it suffers from fairly noticeable distortion - 2.5% barrel distortion at 28mm, 3.2% pincushion at 50mm and 3.7% pincushion at 70mm, and requires correction in-camera or in raw processing.[4]
Its optical performance is competitive with the Sony Carl Zeiss Vario-Tessar T* FE 24-70mm F4 ZA OSS in every metric tested by DxOMark.[6]
Autofocus
[edit]The lens focuses internally, using a linear autofocus motor.[3] Its autofocus is “silent and accurate” and “very quick”.[7]
