Product Description ------------------- 16.6x high ratio zoom lens incorporating 4 FLD glass elements to prioritise the optical performance. Who decides it is impossible to combine portability with image quality? It is understood that the relationship between optical performance and the lens shape is more like a trade-off, and we may need to prioritise one over the other. A high ratio zoom lens often requires compactness and enhancement of additional features to be capable enough to cover various shooting scenes with convenience and versatility. However, SIGMA still believes that image quality is what matters the most. When travelling with minimal equipment the lens needs a wide zoom range especially as a telephoto lens may be needed unexpectedly without time to switch lenses. Even with a high ratio zoom lens, our goal is to satisfy enthusiastic photographers with the versatility of the lens and its optical performance. Therefore, we sought for the point where all the pieces, such as specification, performance and size fall into place and this lens is the fruit of this journey. This is good either as your first interchangeable lens or as a high performance all in one lens. Enjoy the performance of a high ratio standard zoom lens that has "the highest standard for excellent image quality based on each concept", of which Sigma product lines has renewed and established with Sigma Global Vision. This lens incorporates 4 FLD ("F" Low Dispersion) glass elements, which have performance equal to fluorite plus 1 SLD (Special Low Dispersion) glass element. This minimises chromatic aberration, especially toward the telephoto-end, and provide clear image quality with high colour fidelity. The most appropriate optical glass elements are selected to optimize all focal lengths of the lens. From wide-angle to telephoto and macro ranges, it offers superior image quality throughout the entire zoom range. It compensates for the distortion very well, especially at the wide-end, and carries extraordinary expressive capability from the centre to the corners. Flare and ghosting were thoroughly measured and monitored from the lens development stage to establish an optical design which is resistant to strong incidental light such as backlight. The Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even in backlit conditions.
