If you are looking to pay more than £1000 for your camera you are shopping at the professional end of the market. Cameras in this price bracket offer you ultimate control over your photos with a full range of creativity controls.
Improvements over cheaper cameras include better build quality, faster operation and better focusing control. You are also likely to find improved performance in lowlight situations. Another area where you can find better options is when it comes to shooting movies.
If this is your total budget and you do not already have some good quality lens it may be worthwhile considering dividing your budget between a cheaper camera body and a good quality lens or two. This is because the quality of the lens plays a major part in the quality of the photos you take and you are unlikely to get the most out of an expensive camera body if you couple it with cheap lens options.
