No, they didnt. It is just a digital crop. Optically the perspective is still 50mm because you are still standing in the same spot.

Huh ?  What does that have to do with doubling focal length ?

If it is a true telephoto, with the subject at the same size in the frame, you would need to move further away and the perspective would change accordingly.

Why would you have to move further back with a 50 that's "doubled" than with a 100 that's not ?

See how your photos have the same perspective?

And the same framing.  One at 100mm and one at 50mm cropped to emulate 100.

Another clever myth perpetuated by both manufacturers, advertising copywriters and some reviewers.

No "myth" ... it's a crop and everyone knows it; the only question is how good is it.
