how much does a camara that takes pictures like that cost mate only ever had camara phones???
You can go one of two, well, three ways.
Buy a compact with a big zoom on it and you're probably looking at £200 minimum. The images will never be great on extreme zoom.
Buy a pro level slr body and range of lenses...£10k will get you started.
Buy a second hand slr and a second hand lens like the one simmy has and you could pick the pair up for around £200. By far the best option. Buy canon or Nikon cameras and Sigma or Tamron lenses. The images, like simmys will not be perfect but will herald good results.
