Query: The "Nifty Fifty"

Frankly this is a fantastic walk-around lens. It's light, small, cheap yet well-made, and takes consistently great pictures. The f/1.8 makes it a great choice in particular for low light situations and also for nice shallow depth of field shots, as the lens has fairly nice background blur, or bokeh. This is pretty much a must-have lens for a Nikon DSLR.
