Math: Focal length vs cropping
Math: Focal length vs cropping
2 months ago
Can someone enlighten me... I get easily lost when it comes to math, squares and angles.
If you take an image with a 60MP camera and a 200mm lens, and then crop that resulting image to 24MP, what would the equivalent focal length be? About 300?
Is there an equation for this?
