Sigma AF 50mm F2 DG I C lens for Sony FE 

Part of the I series range of lenses from Sigma’s Contemporary line-up, this full-frame standard prime for mirrorless cameras delivers outstanding optical performance in a compact body.

The lens has an all-metal build, including an all-metal hood, metal aperture ring, metal focus ring and even a magnetic metal lens cap. Despite this it weighs in at only 350g and is only 7cm in length, making it a remarkably portable option for photographers needing to travel light.

Thanks to Sigma’s cutting-edge stepping motor technology, the lens focuses very quickly and quietly, and its bright F2 aperture ensures fast shutter speeds in low light as well as a shallow depth-of-field if required. The versatile 50mm focal length makes the lens ideal for street, landscape, portrait, wedding, event and travel photography.

A lens of such optical excellence with such a portable design makes it a superb option for professional photographers on the go.

Excellent Build Quality

As with the other optics in the I series range of premium compact primes, the 50mm F2 has an all-metal build comprising precision-cut aluminium parts. Its robust construction and ultra-portable design make it perfect for a wide range of photographic applications. The lens has a rubber seal around the mount to stop dust and moisture from getting in.

A manual aperture ring allows photographers to change aperture on the lens or, using the Auto setting, on the camera if preferred. The movement of the ring is exceptionally smooth and the clicks well define, ensuring precise operation.

The tactile knurled metal finish used for the lens hood, focus ring and aperture ring make handling the lens and changing settings extremely intuitive. Included with the lens is a magnetic metal lens cap in addition to the regular plastic cap, which further improves ease of use.

• Metal mount with seal: Protects against dust and moisture.
• All-metal construction: Including metal aperture and focus rings.
• Petal-shaped hood: All-metal with individually machine knurled grooves.
• Ultra-compact body: Weighs only 225g, ideal for landscapes, street and travel.
• Aperture ring: With perfectly weighted action for precise adjustment.

Perfect for Portraits

The 50mm focal length is excellent for waist-up portraits, as it gives the most flattering perspective on the face for this composition. The optics are extremely sharp even at F2, ensuring exceptional subject detail.

Beautiful Bokeh

Owing to its bright F2 aperture the lens has a shallow depth-of-field, which helps separate the subject from the background. The out of focus areas are smooth and attractive and don’t distract from the subject.

The bright aperture also allows for faster shutter speeds in low light.

High-Performance Optics

Despite being small and light, the 50mm F2 does not compromise on optical quality. Its advanced optical design includes 11 elements in 9 groups, of which 3 are aspherical elements and 1 is an SLD element. These help keep the lens compact while greatly reducing the appearance of chromatic aberration around areas of high contrast.

A Super Multi-Layer coating on the surface of the elements helps keep flare and ghosting to a minimum.

Magnetic Lens Cap Hoder

Available as a separate accessory, Sigma’s innovative magnetic lens cap holder can be clipped to clothing or a bag to securely hold any I series magnetic lens cap. This helps keep the cap safe while the camera is in use.

Sigma I Series Range

The lens is part of the I series range of primes, which sit in the Contemporary line-up. They are designed to offer mirrorless photographers outstanding optical quality and premium usability in a compact package.

With similar optical character and the same sleek external design, the lenses are ideally used as a set, ensuring consistent bokeh, colour rendition, optical precision and usability.

Made in Japan

All Sigma cameras and lenses are designed, manufactured and assembled at their sole factory at Aizu in Japan. This domestic production model is unusual in today’s industry, with most imaging companies opting to outsource to other countries to reduce costs. But SIGMA believes that keeping virtually all manufacturing, processing and assembly in Aizu is essential for creating innovative, carefully thought-out and impeccably constructed products that meet the high standards demanded by professional photographers and film-makers around the world.
