The most relevant digital camera ratings are those given by users, those that you find reference to in forums. And even that kind of information has to be double-checked. I say you don't decide on what camera model to buy based on the rating. You should check the features, see how they meet your needs, your budget and your skills. Lots of consumers make the mistake of purchasing expensive cameras, and half of the top-notch features remain totally unused.
If you purchase a digital camera, you can enter the producer's website and give a rating or some other form of feedback to the product. That's where you'll see what other customers have said about their cameras. Digital camera ratings are given in view of several elements. The features matter most, from zoom and display to lens, settings and special effect. Comparisons are only possible between digital cameras belonging to similar product categories. What would be the point in comparing a three-year old model with a new release?
Thus, the digital camera ratings for a professional camera are irrelevant for a low-end design. Comparisons are impossible cross-categories, because they lose all significance. Even if you feel impressed by the technical capabilities of a camera and its performance, don't take your information only from the Internet. Why not check the device directly at a local dealer? The experience will be all the more convincing if you know what to look for. Many customers prefer to go to a specialized shop and test all sorts of products, comparing them live.
Reading reviews and checking digital camera ratings cannot compare with the direct testing of the product. But, since this article will most probably appeal to a beginner, you should not let yourself convinced too easily, unless you are really sure of what you are doing. Otherwise you can end up either with a very cheap camera that does not satisfy your needs, or with a too expensive one that is way over your skills in terms of complexity.
