Determine your usage:
The first thing you need to determine before purchasing a DSLR camera is determine your usage of it. If you are buying the camera for taking pictures occasionally and that too not professional then any normal DSLR camera will gratify your need. In addition, one should also know beforehand that whether he/she wants to make videos or not before purchasing the camera.
Budget is another important aspect in determining which DSLR camera to purchase. If you know how much you can spend on buying the camera, it will further shorten down the DSLR cameras that are available in the market. One must also keep in mind the fact that the memory card, body kit, lenses and tripod do not come with the DSLR camera, and they have to be purchased separately. So if you want to buy these items as well then you must cut down your budget even more to accommodate the extra items.
Camera’s megapixels play an important role in determining the quality of your picture. A few years back, an 8mp camera was considered to be one of the finest. However, with several cameras now offering 21mp, the competition has become extremely stiff in all ranges of cameras. Nonetheless, professionals suggest that any camera above than 10mp is a good one.
There are several lenses available for different purposes, and one must know his/her need before purchasing a camera. If you are buying a camera for capturing landscapes pictures, you should then purchase a camera that has a lens of 18mm-128mm. However, if you are buying a camera just to take pictures of your family, then you should consider getting a camera that has a lens of 18mm-55mm, as it will gratify all your needs.
