Beautiful Bokeh and Rendering That can be Enjoyed in Every scene with the SIGMA 45mm F2.8 DG DN | Contemporary, bokeh expressions are specially 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, it's 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 build quality and outstanding operability
Because this lens is intended for everyday use, particular attention has been given to build quality and operability. 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.

Metal bayonet hood
The lens hood features aluminium, using the same material as the lens body which has realized high quality and high rigidity.

Furthermore, cared for the click feeling at the time of when removing and attaching, the knurling process featured on the surface provides superior usability.

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.

Compatible with Lens Aberration Correction
Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.

Designed to minimize flare and ghosting
From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions.

Rounded Diaphragm
The 7-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.


High-precision, rugged brass bayonet mount
The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.

Mount with dust- and splash-proof structure
The mount features a special sealing to make the lens an excellent choice in a wide variety of conditions

Fast AF with full-time manual focus
Full-time manual focus function allows the lens to be switched to manual focus simply by rotating the focus ring.

Note: The operation of full-time MF may vary based on mount type.
