Crop Factor is the relation of the size of the camera's image sensor compared to the industry standard size which is 35mm film format which is called "Full Frame DSLR". To cut the cost of the Camera, manufacturers intend to make DSLRs with smaller imaging area thus the crop factor is conceptualized.

Quick answer, the crop factor times the focal length is the visual equivalent of the focal length on a 35mm camera. So a 35mm, full frame sensor has a crop factor of 1 and crop factors either go up or down from that depending on their relative size. Greater than 1 is a smaller sensor (since it appears as if the focal length is longer compared to a 35mm) ...

Crop factor is the ratio between a full frame sensor (36X24mm) and the sensor you're looking at.
While the same photons go through your lens, a smaller sensor will only "see" part of them as you can see here:
The perspective does not change but because you're seeing only part of the image it seems that you magnify it, hence, 50mm lens on a camera with ...

It is called a crop sensor camera, not a crop lens. The sensor is smaller, just as if you took the same image with a full frame camera and cropped it.
The lens does not know what kind of camera you are using. You could put a "crop sensor lens" on a APS-C, APS-H, FF or medium format camera, and it would still be the same. Put the OP's two lenses on each of ...

Whether a lens is an EF or an EF-S lens, the actual focal length is always used. There are certain technical reasons why this is so, but the simplest is that a lens' focal length is defined as the distance from the film plane needed when the lens is focused at infinity to cast point light sources as a single point on the film plane. This doesn't change with ...

Crop factor isn't a measure of a lens, it's a measure of a sensor. The lens use the same measure, which is actually the focal length of the lens, or the distance the light travels as it is brought to a single point of focus. The reason it doesn't take a lens that long is that a compound lens can move the light around within it. Crop factor is useful for ...

The crop factor applies to all lenses shot on camera with a smaller sensor. They look the same because 70mm is 70mm on both lenses, and they're both cropped in exactly the same way.
I think the answers to Is an EF 50mm f/1.4 the same as 50mm with an EF-S lens on a Canon 550D? should help.
