Description

Select the best lens focal length, aperture, and type for portrait photography based on subject, background, camera sensor, and style to achieve creamy bokeh and controlled depth of field.

Use Cases

Helps portrait photographers choose lenses for headshots, environmental, or group work.

Inputs/Variables Explained

We ask for camera sensor size, portrait style, desired bokeh quality, max aperture preference, focal length range, budget level, and current issue because these determine ideal focal length and aperture (e.g., 85mm f/1.4 on full frame for creamy bokeh). These inputs achieve flattering portraits with controlled depth of field. Limitation: the tool uses standard DOF formulas and crop factor approximations; actual bokeh character (swirl, onion rings) is subjective and lens-specific.

Recommended Lens

Based on your inputs for group portraits with a preference for soft and creamy bokeh, I recommend the following:

  • Focal Length: 35mm
  • Aperture: f/1.4
  • Lens Type: Prime Lens

Explanation of Key Concepts

1. Depth of Field (DOF) Formula

The depth of field is influenced by several factors: aperture, focal length, and distance from the subject. The basic formula is:

[ DOF = \frac{2 \cdot N \cdot c \cdot D^2}{f^2} ]

Where:

  • ( N ) = Aperture (f-stop)
  • ( c ) = Circle of confusion (depends on sensor size)
  • ( D ) = Distance from the lens to the subject
  • ( f ) = Focal length

As you open your aperture (lower f-stop number), the DOF decreases, creating that soft, creamy bokeh effect you're after.

2. Crop Factor

Crop factor is important for understanding how focal lengths translate across different sensor sizes. For full-frame sensors, the crop factor is 1.0. This means a 35mm lens behaves as a 35mm lens, providing the intended field of view.

3. Bokeh Characteristics

Bokeh refers to the quality of the out-of-focus areas in a photograph. A lens with a rounded aperture blade design and a wide maximum aperture (like f/1.4) typically produces smoother and more aesthetically pleasing bokeh, enhancing the soft and creamy look you desire.

Alternatives

Alternative 1

  • Focal Length: 24mm
  • Aperture: f/1.4
  • Lens Type: Prime Lens

This lens provides a wider field of view, which can be beneficial for group portraits in tighter spaces while still achieving a beautiful, creamy bokeh.

Alternative 2

  • Focal Length: 50mm
  • Aperture: f/1.8
  • Lens Type: Prime Lens

Although slightly longer, this option allows for excellent isolation of subjects with a nice bokeh effect, making it a versatile choice for various portrait situations.
