What Is Crop Factor?

Is this photography term important? Do I need to know this? Yes, if you use a camera you need to know this if you use a micro four thirds or cropped sensor camera.

This is the answery bit.

Crop factor is the number that is used to calculate the effective focal length when taking a photo with a cropped sensor camera or a micro four thirds camera.

A full-frame camera has a crop factor of 1 in theory, a cropped sensor camera has a crop factor of 1.5 - 1.6 and a micro four thirds camera has a crop factor of 2.

The crop factor converts the focal length stated on the lens to the effective focal length, for example.

  • 50mm on a full-frame camera is 50mm.
  • 50mm on a cropped sensor camera is effectively 75-80mm.
  • 50mm on a micro four thirds camera is effectively 100mm.

Basically, crop factors relate to the different sizes of digital camera sensors. The term crop factor is very important in photography, we really do need to understand this. This is about the physical size of the sensor, and how this affects the focal length selected and the effective focal length that you get.

But don’t worry, it is not as bad as it sounds. And I will tell you what you need to know and no more, all in plain English.

In this episode, I tell you.

· What crop factor is.

· Why you need to understand this.

· Why it affects the actual focal length that you get with your lens.

· What different crop factors there are.

· And finally, what I do.
