Easily determine the Full-Frame Crop Factor of your various lenses using the following calculator in Excel. If you shoot with a Full-Frame or Crop sensor camera, chances are you have an assortment of lenses. This calculator quickly determines the comparable field of view.
Full-Frame Crop Factor with Different Camera Sensors
Depending on the digital camera brand, APS-C, or crop sensor cameras have various sensor sizes. Typically, Canon cameras typically have a crop factor of 1.6 while Sony’s average around 1.5. A camera is considered Full-Frame when the sensor size is 35mm (36mm x 24mm). A full-frame sensor is the approximate size of 35mm film. In most cases, the larger the sensor, the more that particular camera will cost.
There are plenty of websites online that go into details on crop factors. However, you really only need to understand two concepts.
- Smaller sensors have a narrower field of view than larger sensors when using lenses of the same focal length.
- Full frame lenses on crop sensor cameras will increase the focal view. (55 Full-frame is 82.55 on a crop sensor camera).
Let’s put this into practical terms. Say you are using a Sony A6500 which has a 1.5 crop factor and you want to use the Sony Sonnar T* FE 55mm f/1.8 ZA Lens. This lens is designed for a full-frame camera. If you use this lens on the Sony A6500, the real field of view would be 82.85.
