Body Nikon D5300 lens AF-Snikkor18-140mm How to look at the focal length depends on the focal length and the requirements of photography.

If it is accurate to single digits, such as 27,81,137mm, it can only be viewed by software.

Take a photo with a camera, import it into a computer, and then open the photo with the magic hand of light and shadow to check the EXIF information of the photo, which contains the precise focal length of the lens when taking a photo.

Nikon cameras use the software "opanda IEXIF" to view EXIF information more accurately. Usage: Open a photo with "opanda IEXIF", find the item "Manufacturer's Description" on the right, and then look down to see the exact focal length of the photo.
