With the development of digital photography, attracted companies that have entered the market en masse, and photography began to produce equipment. From this they began to suffer a plurality of customers, who increasingly are confused not knowing what model and what brand preference when purchasing the camera. Certainly not worth investing in equipment of unknown companies. To do this the lens is not enough to think of them. You need years of experience; a firm with a large baggage of photographic experience is not too many. The leading brands are Nikon, Canon and Olympus. The amateur photographs (referred to here for compact cameras) did present themselves Panasonic products (based on optics Licit). Much less is present in the equipment companies reaping audio - Sony and Samsung. Samsung has a decent optics, but poor optics. Sony, in turn (working with Nikon in terms of the matrices) does not have excellent optics. Carl Zeiss glass is no longer the same as prior years. Now, those most polishes glass in China and glass and, unfortunately, are not as precise as in the days when were produced in Germany.
