I'm an amateur photographer and I use a Canon 500D Mark II with the following lenses:
50mm (portrait)
10-22mm (wide-angle)
18-200mm (wide/standard)
70-300mm (telephoto)
24-105mm (standard)

To anyone interested in getting into photography, I'd suggest looking into the Canon Rebel T1i with a lens or two...it's a great camera for the price.
