Sigma 45mm f/1.8 DG DN Lens Sony E-Mount

The Sigma 45mm F2.8 DG DN Lens is great for achieving beautiful bokeh. 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, 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 build quality

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. The design gives consideration to MF operations, and a ring of appropriate torque provides good operability.

High-speed and highly accurate AF enabled by the stepping motor
