Quick Answer

For classic head-and-shoulders portraits with strong background blur, choose the Sigma 56mm f/1.4. If you need a more versatile focal length that captures environmental portraits and full-body shots, the Sigma 30mm f/1.4 is the better fit.

Focal Length and Framing

The 56mm lens (roughly 84mm full-frame equivalent) gives a tight, flattering perspective ideal for isolating a subject's face and shoulders. The 30mm lens (about 45mm equivalent) offers a wider view, letting you include more of the environment or shoot full-length portraits without stepping way back.

Bokeh and Background Separation

Both lenses have an f/1.4 aperture, but the longer 56mm focal length naturally compresses the background and produces softer, more pronounced bokeh. The 30mm f/1.4 still delivers pleasing blur but requires closer distances to achieve similar separation.

Trade-Offs at a Glance

  • Sigma 56mm f/1.4: Best for dedicated portrait photographers who prioritize background blur and a flattering headshot perspective.
  • Sigma 30mm f/1.4: Ideal for shooters who want a single prime for environmental portraits, group shots, and walkaround use. Consider your typical shooting distance and whether you need to include background context.
  • Bokeh Quality: The 56mm produces smoother, more pronounced bokeh at equivalent framing. The 30mm gives decent blur but requires closer focus.
