upgrading, what lens should I buy?

[KaraBee]

Photography started as a hobby for me, but now that I have built up the skills and experience I want to make it a profession. The camera I first bought was a Rebel T3, but I'm looking into upgrading to a Canon 5D mark ii. I have 3 lenses- a EF 50mm 1.4, the kit EF 70-200mm, and the kit EF-S 18-55mm. I really love using my 18-55mm but I know I won't be able to use it on the full frame camera. What's a good full frame lens that's kinda like the 18-55mm. I do have a budget and I love the canon EF 16-35mm, but that's way too expensive. I'm thinking about $500. Thanks!!

Is KaraBee male or female?  A little off your topic but consider your wardrobe also.  Limnited funds at the present means you need to save some money for clothes.  It is very important you don't show up to a shoot, not looking the part.

I prefer dark and I ask my female assistants to wear pants not skirts or dresses. No shorts and certainly not Levi's.

Always remember, if you are going 'pro' go 'pro'.
