Field of View Calculator Visualizer

This is a Field of View Calculator that let you graphically visualize on what kind of field of view (FOV) that you can get when using a specific camera at various focal length. For most modern SLR cameras, there are several crop factors available in the market. Mainly, there are:-

  • Full Frame bodies (35mm) as the reference with the crop factor of 1.0x
  • Canon APS-H with crop factor of 1.3x
  • Canon APS-C with crop factor of 1.6x
  • Nikon DX, Sony, Pentax crop bodies uses crop factor of 1.5x
  • Olympus crop bodies with crop factor of 2.0x

You may read the details at Wikipedia – Image sensor format. Examples are:-

Olympus 4/3 crop

  • All Olympus DSLR bodies.

For most modern consumer level digital SLR cameras, a focal length multiplier of greater than 1 is appropriate because these cameras have a smaller sensor than a 35mm negative. For these cameras a focal length multiplier of approximately 1.5-1.6 is appropriate. Note: This calculator assumes a standard width/height image ratio of 3:2.
