Well then welcome to photography. Just to give you heads up, if it happened that you like it then expect to spend lots of $$$. Now days with digital camera, it is not as expensive as it uses to be. The advantage of digital camera is fast learning curve.
For outdoor photography (nature and cityscape) you need wide angle lens and sturdy tripod. For documentary you will need a wide to mid range telephoto lens. If you are going to do street photography or portrait get a mid range telephoto (100-200 mm), if you can afford VR lenses go for them. For aerial photography you need an airplane, VR lenses will be good investment. For playboy photo shoot, you have to give me a call and I will teach you how to do that.:cheers:
