Impressively Smooth Bokeh
Sporting a f/1.2 maximum aperture, this 50mm prime lens provides rich and beautiful bokeh. Not only is this a massive benefit for creating more artistic and flattering imagery, but it allows you the ability to capture detailed images in harsh lighting conditions.

This lens's rounded 13-blade diaphragm is a first for Sigma and maintains a circular shape, helping create smooth and round bokeh even when stopped down.

Exceptional Build
Constructed with convenience in mind, the 50mm f/1.2 is equipped with multiple functions to assist you while shooting. An AFL button is available for maintaining focus on a single distance. Certain camera models allow for customizing the AFL's function.

The dust- and splash-resistant lens structure combined with the front lens element's water and oil-repellent coating create a durable overall lens that's reliable in the field.

The aperture ring is lockable and can be set to click/de-click depending on your preference.

Additional Benefits

  • Petal lens hood with locking mechanism
  • Rounded 13-blade diaphragm
  • Weight: 1.6 lb

Sigma 50mm f/1.2 DG DN Art Reviews

Not for everyone

I’m really impressed with this lens’ performance. I can see it being used for portrait work, both in and out of the studio. I highly recommend you watch Hugh Brownstone’s YouTube review. It is thorough and unbiased. In fact, it was his video that led me to purchase the lens.

Beyond expectation

This is probably the best lens I have ever owned. Razor sharp and contrasty even wide open. The size is great. It’s not as large as I was expecting. Focus is silent and quick. Huge bang for the buck here - sharper and better handling than the Leica branded SL ASPH lens which I ended up returning.

The Sigma 50mm f/1.2 DG DN Art Lens (Sony E) mantains the same autofocus consistency as Sony native lenses. The only performance affected by this lens, is the ability to shoot 120fps under burst mode.
