50mm 定焦的局限：

50mm f/1.7 was my first lens (and only lens for some time) with my first film camera. 

Although it is nice, it unpractical for photographing (my last few photographing events, listed in reverse time order):

Karate competition, stage performance, birds, party, mathcounts competition.  As a result, I did not use my 50mm this year yet.
