Enter the diagonal dimension of a 35 mm film and the diagonal dimension of the target camera sensor into the Calculator. The calculator will evaluate the Crop Factor. This calculator can also evaluate any of the variables in the formula below if the others are known.
Crop Factor Formula
The following two example problems outline the steps and information needed to calculate the Crop Factor.
CF = D35 / DC
Variables:
- CF is the Crop Factor
- D35 is the diagonal dimension of a 35 mm film
- DC is the diagonal dimension of the target camera sensor
To calculate Crop Factor, divide the diagonal dimension of a 35mm film by the diagonal dimension of the target camera sensor.
How to Calculate Crop Factor?
The following steps outline how to calculate the Crop Factor.
- First, determine the diagonal dimension of a 35 mm film.
- Next, determine the diagonal dimension of the target camera sensor.
- Next, gather the formula from above = CF = D35 / DC.
- Finally, calculate the Crop Factor.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
diagonal dimension of a 35 mm film = 24.5
diagonal dimension of the target camera sensor = 30
CF = D35 / DC = ?
