A constant f/2 aperture across the 28-70mm zoom range effectively replaces a set of fast primes, supported by four XD linear motors for rapid, silent autofocus. Its Nano AR Coating II and 11-blade diaphragm deliver high contrast and smooth bokeh, while the dust- and moisture-sealed build ensures reliability on location. This lens is best for wedding and event photographers who need a single, versatile optic to handle low-light venues and quick scene changes.
