Description
The Sony Vario-Tessar FE 16-35mm f/4 ZA OSS is a compact, dust- and moisture-resistant wide-angle zoom for full-frame FE-mount cameras (also usable on APS-C E-mount bodies), with a constant f/4 aperture.
Optics
Five aspherical elements — including a large-diameter AA element — and three ED elements control chromatic aberration while keeping the lens compact. Carl Zeiss T* coating cuts flare and ghosting for stronger contrast and colour fidelity, and a circular aperture diaphragm keeps defocused highlights smooth from wide open to two stops down.
Handling
Optical SteadyShot corrects up to 4 stops of camera shake for handheld work in dim light. Internal focusing (only the middle groups move) keeps the lens length constant and the front filter thread non-rotating, useful with a polariser.
