Sigma 50mm f/1.4 DG HSM Art Lens for Sigma SA
Key Features
  • Aperture Range: f/1.4 to f/16
  • One Molded Glass Aspherical Element
  • Three Special Low Dispersion Elements
  • Super Multi-Layer Coating
The Sigma SA mount Sigma 50mm f/1.4 DG HSM Lens is a fast standard-length prime designed to achieve high optical performance through the incorporation of both three Special Low Dispersion glass elements and one molded glass aspherical element. These elements, coupled with an advanced optical design, work to minimize sagittal coma flare and chromatic aberrations in order to provide high image sharpness and clarity. The lens' large diameter and floating system also help to correct for vignetting to ensure maintained peripheral brightness. A Super Multi Coating has been applied to lens elements, too, to reduce flare and ghosting for higher contrast and color fidelity.

The lens' large diameter and floating system also help to correct for vignetting to ensure maintained peripheral brightness. A Super Multi Coating has been applied to lens elements, too, to reduce flare and ghosting for higher contrast and color fidelity.

A Hyper Sonic AF Motor, along with an optimized AF algorithm, produces quiet, smooth, and fast autofocus performance that benefits this lens' use in a wide variety of situations. This AF motor also permits full-time manual focusing control for refined precision by simply turning the focus ring at any time.

Sigma Global Vision - Art

As part of the Art line within Sigma's Global Vision series, this lens' is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.

Molded Glass Aspherical Element

This lens has been designed using an advanced optical structure to achieve both high resolution and sharpness along with an aesthetic out-of-focus quality for greater subject separation. A molded glass aspherical element corrects for sagittal coma flare and enables full use of the fast f/1.4 maximum aperture with maintained sharpness and clarity. This design also works to minimize vignetting, color blur, and other distortions help to produce natural and pleasing bokeh for selective focus and shallow depth of field techniques. By reducing these aberrations, this lens is also well-suited to astrophotography or other situations with point-light sources due to its ability to suppress blur near the edges of the frame.

Special Low Dispersion Glass Elements

Three SLD (Special Low Dispersion) glass elements have been incorporated within the lens design to correct for axial chromatic aberration throughout the entire focusing range. This helps to ensure maintained image sharpness, clarity, and contrast regardless of focus point or aperture setting.

Large Diameter Lens

In designing the lens with a large 85.4mm diameter, and placing the widest elements within the front group, greater peripheral brightness is more easily attained when working with larger apertures. This design also lends itself to minimizing vignetting throughout the aperture range for greater clarity and detail across the image frame.

Super Multi-Layer Coating

A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.

Floating System

By employing a floating system, the distance between glass elements is adjusted during focusing in order to limit the amount of lens movement required when shooting. This floating system helps to realize a minimum focusing distance of 1.3' with a maximum magnification of 1:5.6. Additionally, this design also contributes to high detail rendering capabilities throughout the entire focusing range.

Hyper Sonic AF Motor

The integrated HSM (Hyper Sonic Motor) realizes quick and quiet autofocusing, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time.

Other Lens Features

  • A rounded nine-blade diaphragm helps to produce an attractive out-of-focus quality.
  • The lens is constructed using a Thermally Stable Composite (TSC) material, along with traditional metals, for greater precision and use in wide temperature variations. The outside of the lens barrel is also engraved with the year of production.
  • The bayonet mount is constructed from brass for ensured accuracy and durability.
  • The included lens hood is fitted with a rubber connection for a secure fit.
  • This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.

question

Does this lens has image stabilization similar to the Canon 50mm with IS?
Asked by: Anonymous
This lens does not have any stabilization built into it unfortunately. And to clarify, Canon does not offer any 50mm focal with IS Image Stabilization either.

Every body/every lens is a tad different. Mine combo is perfect at -2 and didn't need dock adjustments. To say it WON'T need, any is a bit naive. Just sayin'

Is the focusing issues really that bad like some of the reviews online say so?
Asked by: Anthony
When using the Sigma 50mm f/1.4 DG HSM Art Lens for Canon EF, the excellence of focusing will vary from camera body to the camera body, (and the way focusing is set up on the specific camera body). If one is having a focus problem, their are two ways to potentialy fix the problem: If one sends Sigma the camera and the lens to Sigma they are happy to calibrate and send back (with free shipping back), or one can use the Sigma USB Dock.

How is the autofocus on this compared to Sony lenses for new sony cameras A7s iii, FX9 etc?
Asked by: Leonard
I can’t necessarily compare it to Sony lenses but I do have this with an a7siii and have no complaints. I’ve never had a moment where I felt it needed to be faster or it wasn’t accurate. Maybe Sony is better but I’m very happy with this lens

question

So this lens can work on full frame cameras and crop sensor cameras? I have a D3200 now but eventually want to move up to full frame. Would this lens be a good investment?
Asked by: Anonymous
Yes, that lens is full frame. Meaning it will work on a full frame camera and an APS-C crop camera like the Nikon D3200. It is a very good lens, sharp and fast for low light situations.

Has anyone had issues trying to get a Tiffen 77mm ND filter on this lens? Mine doesn't seem to thread.
Asked by: Francesca
Often with the fine threads that are on camera lenses and filters, finding the threading start can be a challenge. I suggest making sure the rear cap is on and sitting the the lens on a table. Then bring the filter down and touch the lens filter threads. Rotate the filter counter-clockwise (which is the opposite direction of threading) and feel for the slight dip that tells you that you are at the thread opening. Then gently rotate clockwise to thread. If to no avail, then I would suspect damage to the filters thread and recommend an exchange care of the B&H Customer service department.
