Lets say you take the same shot, say a portrait, with a 24mm & 100mm lens from the exact same distance from the subject. The one taken with the 24mm will appear smaller (correct me if I'm wrong at any point). If you blow up and crop this image so it fills as much of the frame as the 100mm image, will the two look the same?
Basically yes. But we don't want to crop that much since we cut down file size, increasing noise/grain and lose detail.
Since You can't fill the frame with the subject equally, at the same distance to subject, with two lenses that have different magnifications. And that IS the point I was making. And that people can't always use one lens to do the job of another, because it forces them to change distance, and thus change perspective. Also, a lenses angle of view is rated at infinity only. Once they're focused closer, their angle of view can vary.
Another way... If you leave a camera at the same place after taking a shot with a lens which has greater magnification than the one you are now using, you can not get the same magnification without cropping. And, if you don't crop, you have a different perceived perspective, simply because you'll have more background in the image, and a smaller primary subject. Here again, It's the difference between magnification which causes people to change camera to subject distance, thus changing perspective. And this is the lens characteristic I'm speaking about.

But again it's not the lenses that do it it the distance. If you use them right it not an issue
What have I been saying? But if you don't have the right lens, what do you do? You wind up with a shot of less than desirable look.

I don't understand why you keep repeating that I'm wrong, only to say something I've already pointed out!
