I'm confused between the sigma 70-200mm, nikon 10-24mm, or a D7000?

I'm a beginner and I'm confused between the nikkor 10-24 f/3.5-4.5G ED, the nikon D7000 and the sigma 70-200mm, which one do you think i should buy, currently i have the nikon D3100, nikon 50mm 1.8g, 18-55vr and the 55-300mm. So do you think i should buy the D7000, 70-200mm or the 10-24mm.

I think you should stick with what you have & not buy anything until you understand something about photography - these are solutions to a problem you don't seem able to define

If you can't choose between two completely different lenses that have two completely different uses, then you don't really need either of the two

stick with the 18-55mm and 55-300mm and wait until you know what you want. Buying lenses for the sake of buying lenses is wrong.

you also don't need to upgrade cameras. Stick with what you have and in time you will know what you want

@basha, so you currently have a camera and some lens and new ones came out and not sure what to get?

I would say get back to the drawing board, know what type of photography you like best and then find the gear that fits that purpose. Looking at what you got for now and your question. I say, stick to what you have currently until you get to the point where you have outlast it's usage. Unless you have that thing that they call… Er.gear acquired syndrome? --- G. A.S. Won't help you take better photos by the way. Only your eyes and creativity do and yes, the gear helps… To a certain point.
