Not always - and so what if it does? Do you think hunting with a long lens results in more interesting or compelling photographs? I guess it depends on what you want to photograph. You can learn to be unobtrusive and accepted when photographing closer in - it may take a little practice and certainly you may need to develop some sensitivity to the people and the environment, but, imo, the results become much better. Look at your photos with a critical eye, compare them, perhaps, to the results obtained by others (Capa, Lange, Salgado, Nachtwey, Smith, Chim, Morath, Arbus, Erwitt, Dickey Chapelle, Barbey, Richards). You might consider taking a look at this page: http://tinyurl.com/4495z and see if the work of any of these photographers represents what you want to do, then get yourself a 50mm lens and go out a make some photos.
