Emphasising image quality. This is a SIGMA's new all-in-one lens.
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.
Excellent optical performance that satisfies experienced users
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.
Accumulated lens technology leads to superior image quality
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.
Renewed OS system for higher compensation
By reviewing the system construction and the algorithm of firmware, 3.5 stops of compensation has been achieved.
Zoom-macro for enhanced macro photography
Just by rotating the zoom ring, it enables photographers to take close-up pictures of subjects such as jewellery and flowers. The maximum magnification ratio at respective focal lengths is indicated on the lens barrel, thus it is easy to see what the object size will be at the sensor. Furthermore, in order to secure a clear field-of-view, the design of this lens is very thorough, even down to the precise position of the engraved letters on the lens.
Newly Developed Hyper Sonic Motor
For comfortable and smooth use with the high zoom ratio, 16.6 times, it incorporates a bigger HSM (Hyper Sonic Motor) which is newly developed for this lens. It is powerful enough to ensure high speed and quiet AF.
Designed to minimize flare and ghosting
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.
SIGMA USB DOCK - Customizable to your needs
With the optional SIGMA USB DOCK and the dedicated special software “SIGMA Optimization Pro”, you can update your lens firmware, or adjust focus points by attaching this lens to a SIGMA USB DOCK connected to a computer.
