For many years I´ve been used to shoot SLRs with either WA or Tele lenses, depending on what did I need at the time, and sometimes (very few) with the normal lens, when I needed to get really closer to the subject or just macro. I have to admit that I forgot almost completely the "normal" lens (say it something from 45 to 58 mm) for every day photography. After realizing that almost 100% of my actual shooting is with a "normal" lens, just because the RFs I have are either fixed lens or I have no other lens but the 50 mm, I think now that this one is the most versatile lens If used properly. I´ve learnt again to use my feet for framing, and most important, there were very few times I really needed something else.
Of course, it doesn´t mean that I won´t use a tele or WA anymore. I do it, but my everyday lens is the normal (any way I´ve not too many choices!).
