A 50 mm is one of my special occasion lenses, the others being a 80-200 and a 300, the latter often combined with a TC. The 50 is great for low light, for street photography and small enough to carry with you. Street ohotography because you stand out much less with a DSLR without battery grip and a lens as small as a 50 mm. Low light, because of f1.8. The one lense that is on most of the time, especially when travelling, is a 24-120. I still would recommend a 50mm, simply for its convenience, low light performance, small size, incredible sharpness, speedy AF and beautiful image characteristics from backgrounds to sun stars.
