The Opera 16-28mm F2.8 FF is a super wide zoom lens featuring super wide angle at 16mm and traditional wide angle at 28mm that stands at the border where the standard zoom angle range begins, thus providing the photographer practically full wide angle coverage with only one lens.
Super wide angle, superior resolving ability coupled with high contrast and beautiful bokeh rendering, fast f/2.8 constant aperture throughout the zoom range and accurate AF drive system make this lens attractive for photographers who specialize in landscape, interior architecture, street snap, documentary, environmental style portrait and night sky/time lapse photography genres.
