With the development of digital photographic equipment, two main trends are steadily observed – an abrupt increase in the resolution of CCDs and a gradual decrease in prices in each of the categories of cameras. However, there are a number of market niches in which the price remains the same, but at the same time there is a constant qualitative improvement in cameras. By “quality improvement” we should understand not only the increase in sensor resolution, but also the improvement of lenses, ergonomics, a set of service functions – in short, all that allows you to get good pictures without extra effort on the part of the user.
