So I bought a 50mm Lens today for my D300 because I'm shooting a wedding for a friend as a favor. I had always been told that a 50mm is a very good lens for portraits, and that a prime lens, even the cheaper ones, are usually sharper then even the most expensive zoom lenses. Wasn't but $150.00. So playing with it just now I realized that anything beyond about 7 foot distance that everything appears almost the exact size in the photo (as long as the photo hasn't been resized) as the object from the same distance. I had read that lenses in this range, always called standard lenses mimic the angle of view of the human eye. Is that what they were referring too? People always talked about standard lenses and angle of view, but not much more then that.
