Unlock the secrets of your camera's sensor size! Our Crop Factor Calculator helps photographers quickly determine the effective focal length of their lens on a crop sensor camera. Understand how your APS-C or Micro Four Thirds sensor affects the field of view compared to a 35mm full-frame sensor. Get precise results for better photography planning and lens comparisons.
Formula:
The formula for calculating effective focal length is straightforward:
Effective Focal Length = Actual Focal Length × Crop Factor
Where:
- Actual Focal Length: The focal length written on your lens (e.g., 50mm).
- Crop Factor: A multiplier representing your camera's sensor size relative to a 35mm full-frame sensor (e.g., 1.5x for Nikon/Sony APS-C, 1.6x for Canon APS-C, 2.0x for Micro Four Thirds).
