Clarification: 35mm equivalent refers to the capability of a digital camera to act like a 35mm-wide film format of several years previously.
When mentioned in the specifications list, 35mm equivalent is a reference to the lens focal length of a digital model, as you can compare it to a camera with the 35mm film lens. As listed in the list of specification, you will commonly see the 35mm equivalent in a range of measurements, for example, 28 – 280mm. This feature is very useful for comparing one lens to another lens.
If the measurement of a lens is smaller than 35mm, it is known as the capability to shoot photos at wide angles. And when the measurement is greater than 70mm, you can have the telephoto shooting capability. A 50mm distance is the measurement within the human vision without the support of any telephoto or wide-angle capability.
