The Sony 16-80mm is a Carl Zeiss branded lens featuring a Vario-Sonnar design. It uses 14 elements in 10 groups, with 3 aspherical elements and a special ''T* Coating'' to reduce flare. The lens uses 62mm filters, and the filter mount won't turn during focusing or zooming. It ships with a petal lens hood and a carrying case.
Representing the conventional 24-120mm lens in 35mm film terms, the Sony 16-80mm ƒ/3.5-4.5 is a better version of its 18-70mm ''walkaround'' lens. Going slightly wider and longer, and equipped with a better maximum aperture, it's also significantly more expensive at around $650 on store shelves. Read the whole test here
