So your question is?
Telephoto is for getting pictures of things farther away, wide angle is for pictures up close where you want more to be in the field of view. Wide angle tends to distort things at the edges like making straight lines into curves. You might use one of these to shoot yourself taking a shot. The telephoto would be used to show the antlers on a deer sneaking through the brush. I think the more it is zoomed in, the less your depth of field will be (the area in focus).
I am sure there are more informed folks to answer your question but maybe ask a more clear question.
Good luck.
