- 2. How to calculate equivalent focal length. Having determined your crop factor, divide your full-fame focal length by it. Full-Frame Focal Length / Crop Factor = APS-C Focal Length. 50mm / 1.5 = 33mm. Therefore, the APS-C equivalent to a 50mm lens on a full-frame camera is 33mm. Both will get you to that 47-degree field of view.

- Focal length formula to calculate focal length. When a lens is used to form an image of an object, the distance from the object to the lens (u), the distance from the lens to the image (v), and the focal length (f) are related by: 1/f = 1/u + 1/v. The formula of focal length for the measurement described above is: f ≈v.

- The identical tan is produced by half the image height on the sensor / focal length. So (sensor_height/2) / focal_length = height/distance = tan (alpha) so (IW/2) / fx = tan_alpha invert fx / (Iw/2) = 1/tan_alpha fx = Iw/(2 x tan_alpha)

- This information will change your focal length calculation. An online focal length calculator can help you make these calculations. You can also determine focal length by measuring the distance at which a lens focuses on a distant source (or by using a tool called an optical bench).

- The focal length of the lens determines how zoomed-in your photos look. The higher the number, the more zoomed your lens will be. Different focal lengths change how visually close the subject is. Focal length comparison of shots taken from the same position. Perspective Compression. Focal length also affects how objects look in relation to each other.

- Photographic lenses generally have a focal length of between 14mm and 600mm, although there some expensive exceptions that have shorter or longer focal lengths. The shorter the focal length, the wider the field of view. The longer the focal length, the narrower the field of view. Here’s a photo taken with a focal length of 18mm on my Canon 650D. And here’s a photo …

- In other words, Effective Focal Length is equal to Focal Length multiplied by the Crop Factor. As simple as that. For instance, if you have a lens 24-70mm, then the actual, effective focal length on the amateur Nikon camera with crop factor = 1.5 will be 36-105mm. This focal range increase naturally affects the angle of view because the longer the focal length, the …
