People are always under the impression that bigger and more is better. Sometimes this can be true but not always. In the case of digital cameras we know that many prefer smaller cameras but many also are after more mega pixels. The question is if this is necessary. There is a big difference between a two and five mega pixel camera. But is there really such a significant difference between a five and a seven or a seven and a ten if you are not planning on blowing the picture up to the size of a building?
