Nikon - Normal AF Nikkor 50mm f/1.8D Autofocus Lens

For the price, this is a great lens to own.  I use this lens to shoot indoors because the aperture is so big that I hardly ever need to use a flash especially when I raise the ISO to 1600.  The only downside is that 50mm (75mm film equivelent), is a little long for full body shots indoors, but is great for close ups.  Because of close quarters indoors, the subject area tends to be around 3-4 feet tall (so half a person's height).  With that limitation in mind, it works great for candids, shots of babies and kids, 1/2 body, and close-up portraits.  It would also work well for concerts assuming you're within about 30 feet of the stage, and other situations where a flash is inappropriate.
