Another thing about lenses, i only own 3 lenses, a simple cheap 50mm (called a nifty fifty). Its plastic but very light. it is great for portraits or just walking around and cost about $75 used.

I also own a 70-200 2.8 and a 24-70 2.8. These two lenses are expensive. I bought my 70-200 new, which was $1500. I bought my 24-70 used off Ebay for $700. That was over half the price it was new, and there was not a thing wrong with it.

Since you have a cropped lens, you can get some great lenses for less than $500. Check out Tamron, they make a great lenses that won't break the bank.

Any other lens I may need, I rent them. I am going to Italy in a few weeks, and I am renting a fisheye lens. This is a $1000 lens that I am renting for $100.
