Description

Sigma 50mm f1.4 DG HSM Art Lens

The Sigma 50mm f1.4 DG HSM A lens is a high-performance, large aperture prime to join the Art line within Sigma’s Global Vision series, ideally suited for creative and artistic applications for photo and video use. Designed with a focus on sophisticated optical performance, this fast standard-length prime employs Special Low Dispersion (SLD) glass and Sigma’s Hyper Sonic Motor (HSM) system to achieve fast, silent AF and the highest resolution in the focus point and exceptional rendering performance, even near the edge of the image. Furthermore, the lens firmware and adjustment parameters such as focus can be updated with the use of the Sigma USB Dock (available separately).

Astonishing rendering performance

Utilizing know-how and the latest design technology accumulated through the past developments, it corrects the aberration thoroughly and achieves high resolution and astonishing rendering performance even near the edge of the image.

Achieving both high resolution and beautiful bokeh

While pursuing a high level of resolution on the focused point, bokeh in front and behind the point of focus is carefully maintained to have soft rendering. Aberrations including sagittal coma flare and colour distortion that affect the image quality are thoroughly corrected. From open aperture, high-definition rendering without blur is achieved. Moreover, by ensuring vignetting at the minimum and preventing colour blur around the front and back of the focus point, it also achieves natural bokeh.

Excellent correction of sagittal coma flare

It is ideal for a wide aperture standard lens to have a high rendering performance from open aperture throughout the entire image. For instance, the moulded glass aspherical lens elements provide excellent correction to sagittal coma flare. It is perfect for astronomical photography and shooting of illumination because of the reduced blur on the point light sources near the edge of the image. It also creates an attractive bokeh in portraits and indoor shooting.

Correction of axial chromatic aberration

For axial chromatic aberration that is hard to correct even during the image processing, SLD (Special Low Dispersion) glass elements are incorporated, ensuring high image quality throughout the entire focusing range. The lens achieves sharp and high contrast image rendering.

Minimized distortion

It is not possible to compensate for distortion just by changing the aperture values. Thus, the lens development stage was vital in ensuring minimized distortion. The “SIGMA 50mm F1.4 DG HSM” has positioned each glass element to optimize the power layout at respective positions and succeeded in minimizing distortion.

Rich peripheral brightness

It secures very rich brightness in the peripheral areas, which can be a common problem for a lens with a large diameter. By positioning wide elements in the front group, it has improved the efficiency at large apertures. Since it is capable of minimizing vignetting, very clear depiction across the image is ensured.

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.

Minimum focusing distance of 40cm

The lens incorporates a floating system that adjusts the distance between lens groups while focusing, thereby reducing the amount of lens movement required. This achieves a minimum focusing distance of 40cm and a maximum magnification ratio of 1:5.6. As there is less variation in aberration at different shooting distances, the lens delivers high rendering performance throughout the entire focusing range.

Hyper Sonic Motor ensures High AF Speed

The HSM (Hyper Sonic Motor) ensures a silent, high-speed AF function. Optimizing AF algorithm, smoother AF is achieved. Also, this lens can offer full-time MF function by rotating the focus ring of the lens while autofocusing. Without changing the AF/MF Focus Mode Switch, it allows faster focus adjustment. * The default setting of Full-time MF function varies for each mount.
