The Sony FE 24-70mm f/4 ZA OSS Vario Tessar is a full-frame E-mount zoom lens designed for Sony E-mount cameras. Key features include:
Full-Frame E-mount. As a part of the FE line of lenses, the FE 24-70mm f/4 is designed to cover the full-frame sensors in Sony E-mount cameras. Since it’s an E-mount lens, it’s also fully compatible with APS-C NEX cameras.
Normal-Range Zoom. When used on a full-frame camera, this lens covers the wide to normal/short telephoto focal range, making it great for portrait and event photography. With an APS-C sensor camera, you’ll have a focal length equivalent to 36-105mm. The constant f/4 aperture isn’t quite fast enough for low-light shooting, but it’s better than a variable-aperture zoom.
Internal Focusing. The internal focusing system has enables faster focusing speed. The non-rotating front element enables this lens to use polarizing filters, and the barrel doesn’t extend during focusing. The linear-focusing motor enables silent autofocus performance for both still and video shooting.
Optical Image Stabilization. The in-lens stabilizer allows you to shoot at lower shutter speeds without having to worry about camera shake.
Advanced Optics. The FE 24-70mm features five aspherical elements and one extra-low dispersion element. This minimizes chromatic aberrations throughout the zoom range while producing clear, high-quality images. Additionally, the Carl Zeiss T* anti-reflective coating eliminates lens flare and ghosting while providing the famous high micro-contrast Zeiss look. Its seven-blade aperture diaphragm gives images smooth out-of-focus areas when you desire a shallow depth of field.
High Build Quality. Like the Sony a7-series cameras, the FE 24-70mm offers dust- and moisture-resistant sealing for use in less-than-ideal conditions. The all-metal barrel and smooth, responsive zoom and manual-focus rings give this lens a solid feel.
