Sony's premium APS-C standard zoom — 24-105mm equiv at constant f/4 with Zeiss T* and OSS.
The Sony E 16-70mm f/4 ZA OSS Vario-Tessar T* launched in 2013 as Sony's premium standard zoom for APS-C E-mount. The Zeiss Vario-Tessar T* designation with constant f/4 and OSS made it the best APS-C standard zoom for Sony.
Optically good — Zeiss T* coating provides excellent contrast and flare control. Constant f/4 maintains consistent exposure. OSS stabilisation. The 24-105mm equivalent range covers standard walkaround needs. Good for both stills and video.
Sony E mount with 55mm filter thread. Approximately 308g — remarkably compact for constant f/4 with OSS. APS-C coverage. Zeiss T* coating. Minimum focus distance 35cm. No weather sealing.
Available used at mid-range prices. The Sony E 16-55mm f/2.8 G is faster. The Tamron 17-70mm f/2.8 has more range. This remains the only Zeiss-branded APS-C constant f/4 zoom for Sony. For those wanting Zeiss quality on APS-C.
