I created my own layaway plan: Purchase
Adorama or
B&H gift cards every time I have a little cash to put towards gear. I can't spend them anywhere else!
Buying lenses until you learn about shooting is kind of a waste. You will find down the road that if you just go and purchase what you THINK you want and need, it won't be what you want and need in 6 months.
I will recommend that you purchase the 50mm f/1.8 lens. First it is uber cheap for what it is. Second it is a prime lens. You will get a taste of great sharp images as well as a prime lens (no zoom) and a low light lens. It will definitely help you to learn about your style and what you want out of your lenses. It will also make it easier to learn exposure if you have a lens that doesn't change aperture as you zoom.
As for accessories you'll want right away a good, basic tripod. A remote trigger. You will eventually need a good, dedicated speedlight. I think by beauty pictures you are talking glamour photography... that is a loaded gun. You will need a lot in terms of lighting and modifiers, but you can get there. Before you can decide what YOU need you need to learn about photography and how to shoot.
A good camera bag is a necessity.
Get the Magic Lantern guide for your camera. It's very useful. Keep it an your manual in your camera bag.
Then add to it THE BOOK (yes, I am recommending it guys!) Understanding Exposure by Bryan Peterson
The 4 book set from Scott Kelby Digital Photography (1-4) You can find the boxed set on
ebay for a decent price.
The Moment It Clicks by Joe Mcnally.
You will need a good editing program. Photoshop Elements 10 is great from beginner to advanced and runs under $100.
