Sony E 16-70mm f/4 ZA OSS Vario-Tessar T* - Sony E-mount

The E 16-70mm f/4 ZA is a premium mid-range zoom for APS-C E-mount cameras, developed in collaboration with Zeiss. It maintains a constant f/4 maximum aperture throughout the zoom range and includes Optical SteadyShot (OSS) image stabilisation. The T* coating helps maintain high contrast and colour fidelity, making it a significant upgrade over standard kit lenses for enthusiast photographers. Potential buyers should check for decentering, a known issue where one side of the image is softer than the other; SDS performs specific tests to ensure optical alignment. The metal barrel is prone to small scratches, and the zoom action should be checked for consistent resistance. We also verify that the OSS system engages silently and effectively, as well as checking the electronic contacts for wear.
