The new lenses will be released over the next few months with the last appearing before the new year.
The line-up includes two new additions to the ART range, two sport lenses and a contemporary lens, covering an entire range of focal lengths and meeting a variety of photographic needs.
The two new ART lenses, the 28mm and the 40mm, use a combination of low dispersion glass elements and special low dispersion glass elements to improve the correction of magnification chromatic aberration, with the 40mm using three of each glass elements and the 28mm using two, in combination with three aspherical lenses to achieve a sharp image. The high resolution covering the entire sensor on both lenses effectively corrects coma flare and minimises distortion, showing consistently less than 1% distortion with the 40mm.
Both lenses are designed with water, oil and dust repellent coatings, making them an adaptable companion for difficult weather and location conditions. In addition, the hypersonic motor provides a high-speed AF, making the lenses ideal for instantaneous image capturing.
The new 56mm contemporary lens makes the third addition to Sigma’s f/1.4 mid-tele lens series, completing the large aperture series. The 56mm is a compact lens designed primarily for video shooting, with use of a stepping motor to achieve quiet and smooth autofocus. The AF tracking, compatible with the Sony E-mount, allows continuous focussing on the face or eye for sharp images even when the subject is moving within the shot. Additionally, the lens benefits from an open aperture to achieve bokeh and brightness even with APS-C sized cameras, which commonly have smaller bokeh effects compared to the full-sized systems.
The final two lenses announced expand the Sigma sports line with the new 60-600mm telephoto lens and the evolved 70-200mm. The two lenses are functionally designed to make the shooting experience as comfortable and durable as possible, with these robust cameras incorporating magnesium alloy into their multi-material structure to reduce the weight of the overall lens in addition to the dust, splash and oil repellent coatings.
Both lenses provide high resolution images with magnification and colour aberration correction utilising a combination of low dispersion glass elements. The 60-600mm has a lens construction of 25 elements in 19 groups, while the 70-200mm uses a total of ten exclusive low dispersion glass elements enhancing the spherical aberration, which is demonstrated best when used in portrait photography.
Additionally, with the incorporation of an AF button on the 70-200mm lens, allocation of functions is possible, meaning the photographer can customise the lens for best use. The 90°click-stop tripod socket on the 70-200mm eases the change in camera position from vertical to horizontal, and vice versa.
