Newly developed high-performance lens series for full-frame mirrorless cameras
With mirrorless cameras emerging at an accelerated pace, expectations towards lenses suited for high-performance full-frame mirrorless cameras are growing. Unfortunately, many photographers may feel that they have little choices for mirrorless lens systems in terms of performance, size, extensive lineup, and due to the burden of having to use multiple systems. SIGMA has thus developed and proposes this new full-frame mirrorless lens series as the optimal solution to this challenge.
SIGMA will develop interchangeable lenses with unprecedented specifications and performance by designs that benefit from the short flange focal length feature of mirrorless cameras while retaining the concepts of “Contemporary,” “Art,” and “Sports.” We will announce three models as the first lenses from this series.
Beautiful bokeh and rendering that can be enjoyed in every scene
With the SIGMA 45mm F2.8 DG DN | Contemporary, bokeh expressions are especially featured. Spherical aberration has been controlled to ensure not only the large bokeh in the front and rear of the subject but also the rear bokeh near the area in focus create a gradient to a soft blur. This lens softens the periphery of blurred images suppressing the double-line bokeh etc. and enhances the three-dimensional impression of the subject with the smooth expressions in the foreground and the background. In addition, its minimum focusing distance of 24cm makes it possible to enjoy shooting snapshots and tabletop photos taking advantage of the angle of view. The design gives consideration to vignetting to achieve beautiful round bokeh and subdue swirly bokeh in the whole bokeh effects.
While this lens produces smooth bokeh effects of which one could say as “classical expression” when the aperture is wide open, it also realizes modern sharp rendering when it is stopped down. It is reassuring to hold this lens as the regular lens for everyday use.
High-speed and highly accurate AF enabled by the stepping motor
The lens is capable of smooth, quiet and high-speed AF made possible by a stepping motor, as well as supports Face/Eye Detection AF and video AF. The design gives consideration to MF operations, and a ring of appropriate torque provides good operability.
High build quality and outstanding operability
Because this lens is intended for everyday use, particular attention has been given to build quality and operability. The bayonet hood feels comfortable when removing and attaching, and the lens barrel incorporating metal material as the main part achieves improved durability. Furthermore, thanks to the aperture ring with the right click feeling, comfortable operability during various shooting styles is ensured.
