This question already has an answer here:
I want to buy a new lens (canon ef 50mm f/1.8 stm) that I know that the real focal length in my camera is around 80mm, but my question is if this happens in the same way whit my actual lens (18-55mm). If I take a photo whit the 18-55mm in 50mm and take another one whit the 50mm will I have the same focal length?
edit: First of all, thank you for your answers! I know that the focal length is in the lens and it doesn't change.
I think that I wont to say it was about the 'crop factor' or "how many people enter the two photos without me or the people moving?" the same? less in the EF? more in the EF? I think that the same.
Thank you again and sorry for my bad English.
