50mm vs 85mm Portrait Comparison

At same f/1.8 and 2m distance
50mm Lens (Standard Portrait)DoF: 16.9 cm
👤Field of view: 46.8°

Best for: Full-length portraits, street candids and tight indoor spaces. Shows more of the surroundings while keeping natural proportions.

85mm Lens (Telephoto Compression)DoF: 5.7 cm
👤Field of view: 28.6° (compressed)

Best for: Tight headshots, outdoor fashion and maximum background blur. Flatters facial features and pulls the background closer.

How to use it

  1. Select your camera sensor type (Full Frame, APS-C, or Smartphone).

  2. Enter your lens focal length (e.g. 50mm or 85mm).

  3. Choose your aperture (e.g. f/1.8 for shallow blur or f/8 for deep sharpness).

  4. Set the distance to your subject to see exact near, far, and total sharp zones.

Depth of field calculations are based on standard circle of confusion (CoC) values. Actual perceived sharpness also depends on print size and viewing distance.

Frequently asked questions

How do I calculate Depth of Field (DoF)?

Select your camera sensor type (Full Frame, APS-C, or Smartphone). Enter your lens focal length (e.g. 50mm or 85mm). Choose your aperture (e.g. f/1.8 for shallow blur or f/8 for deep sharpness). Set the distance to your subject to see exact near, far, and total sharp zones.

Which is better for portraits: 50mm or 85mm?

50mm is versatile for full-body and indoor portraits where space is limited. 85mm provides superior facial compression, flattering proportions, and cremater background bokeh separation for outdoor and tight headshots.

What is hyperfocal distance?

The focus distance that gives your image the maximum possible depth of field, from half of that distance all the way to infinity. It is essential for sharp landscape photography.
