50mm F1.8 lens
Price: €130-€150 (from Conn's Cameras) Rating: HHHHH
LOTS of people have moved up to full-sized cameras in the past two or three years. But many beginners and novices simply settle for the kit lens that comes with the camera. Or they buy a zoom lens. These are good for some things. But for shooting portraits -- or people in general -- there is one lens that I have found beats most others.
The lens to get your hands on is the ultra-affordable F1.8 50mm model. Because it ranges down to F1.8, you get stunning depth of field (which is to say that the background to your shot blurs away beautifully), sharpening your subject. Both Canon and Nikon (still the two most popular brands for full-sized cameras) sell this model. If you know someone who has a Nikon or Canon camera, you won't go wrong here.
