With zero knowledge SLR will do nothing. Regardless of the price, this is advanced equipment showing a claw in the hands of an informed user. It's worth it if you are determined to quickly absorb knowledge and exercise. Exercise is a situation when you do not have to take pictures but master some functions, techniques ...
Looking from a different angle, when it comes to something more than a photo for a family album or a social networking site, it is worth going into a SLR camera. If only then the SLR will disturb the weight but also because it puts more requirements than the compact which takes everything by itself and if you move it will stabilize.
Compact restrictions? You won't print a1 poster, but you probably won't print it. Anyway, a SLR camera with kit for 500 zlotys will not cope either. The second limitation of compactness is difficult lighting conditions. Small lights shine up to 2-3 meters.
Quite a few drawbacks, right?
There is something else sometimes called a bridge camera. It's such a cool compact. Fuji, who suggested above, is such a cool compact (not a SLR!). It differs from an ordinary compact camera in that the lens is not miniaturized and therefore may have better parameters. For a large lens, a larger matrix is often hand in hand. The size of the matrix is worth paying attention to even when compact. Simplifying the larger the more light it catches. Simplifying because without simplifying someone can stuff too many pixels on this larger matrix and then loiter from catching light. The 30x zoom, 30 million pixels sound nicely marketing. Only a small zoom makes the lens very dark. Many pixels require more computing power, a larger card, more current and at the same time spoils a very important parameter - useful sensitivity. And this is especially important in a machine that can afford to set a little too high ISO and then skim.
Any examples of models up to PLN 500? And what to look for most when choosing.
