Sigma 50mm f/2 DG DN C (Contemporary) Full-Frame Autofocus Lens for Sony E-Mount, Black {58}

Sigma 50mm f/2 DG DN Contemporary: the compact full-frame standard prime.

At 350g and 68mm long, this lens slips into a bag without negotiation. The 50mm focal length on a full-frame Sony E-mount body gives you a field of view close enough to natural human sight that framing becomes instinctive, which matters when you're working fast on the street or pivoting between subjects at a portrait session. The f/2 maximum aperture separates subjects cleanly from backgrounds without the handling penalties that come with faster glass.

Optically, Sigma packed 11 elements across 9 groups, including 3 aspherical elements and 1 Super Low Dispersion element to keep aberrations in check across the frame. The 9-blade rounded aperture diaphragm shapes out-of-focus areas smoothly, which portrait and documentary shooters will appreciate. Internal stepper motor autofocus keeps the barrel length fixed during focus pulls and runs quietly enough for video work. Weather sealing, a 58mm filter thread, and a supplied hood round out a lens built to actually go places.

At this focal length and maximum aperture, on a native Sony E mount with weather sealing baked in, this is a serious working lens priced where most photographers can actually afford to use it daily than protect it.

Who It's For

Street photographers get a weather-sealed, pocketable lens that autofocuses quickly and draws no attention at 70mm diameter. Portrait shooters working with Sony full-frame bodies benefit from the f/2 aperture and 9-blade rounded diaphragm for controlled background separation. Videographers will value the internal focus mechanism and stepper motor, which eliminate barrel creep and minimize focus noise on-mic. Travel photographers who want one lens to cover most situations will find the 50mm field of view and 0.45m minimum focus distance workable across environmental portraits, interiors, and everyday scenes.

FAQ

Is this lens good for portraits?

Yes. The 50mm focal length on full-frame gives you a natural perspective for head-and-shoulders work, and the f/2 aperture with 9 rounded diaphragm blades produces smooth background separation without the bulk of faster glass.

How much does the Sigma 50mm f/2 DG DN weigh?

350g (0.77 lb). It's compact enough to carry daily without fatigue, paired with a barrel diameter of 70mm that fits standard camera bags.

Does this lens have image stabilization?

No. On Sony E-mount bodies with in-body stabilization, you'll get stabilization from the camera. On bodies without it, you'll need a steady hand or a tripod for slower shutter speeds.

What's the minimum focus distance?

0.45m (17.72"). You can focus as close as about 17.7 inches, giving you some working room for detail shots without extension tubes.

Can you manually focus while autofocusing?

No full-time manual focus. You'll need to switch the camera or lens to manual focus mode to adjust focus by hand.

What weather sealing does this lens have?

The lens is weather sealed against moisture and dust. Combined with a weather-sealed Sony body, it's built to handle variable conditions on assignment.

What filter size does this lens use?

58mm. A standard size, so you can share filters with other lenses if you have them in that thread.
