Product Highlights
- XA element for breathtaking resolution : Superior G Master resolution is achieved throughout the entire 70mm to 200mm zoom range at all focusing distances. Two aspherical lens elements, one an XA (extreme aspherical) type manufactured to 0.01-micron surface precision, effectively control distance-related aberration so that outstanding resolution is ensured throughout the image area.
- Aberration controlled for superb images : Two spherical elements that use ED (Extra-low Dispersion) glass, plus two more that use Super ED glass significantly reduce chromatic aberration for sharp reproduction without colour bleeding. ED aspherical element is also used, simultaneously suppressing chromatic and spherical aberration that are common issues in telephoto lenses.
- Excellent close-up performance : This lens offers excellent close-up performance for a zoom. Minimum focus is 0.4 meters (1.32 ft) at 70mm and 0.82 (2.69 ft) meters at 200mm. Maximum magnification is 0.3x. Deep bokeh at F2.8 adds extra expressive close-up capability. Floating focus ensures pinpoint sharpness even at minimum focus distance, while inner focus makes it easy to get close.
- Stunning G Master bokeh : An XA element manufactured to 0.01-micron surface precision suppresses onion ring bokeh, while precise spherical aberration control boosts bokeh quality. ED (extra-low dispersion) and Super ED glass spherical elements, plus one ED aspherical element, effectively minimise colour bleeding for beautiful bokeh without unnatural colouration.
- New high-performance aperture unit : TEven the aperture unit in this lens has been refined to meet the highest G Master quality standards. A newly developed 11-blade aperture unit that remains almost perfectly circular from wide open to stopped down by two stops helps to deliver the kind of natural-looking circular bokeh users have come to expect from a G Master design.
