Any professional photographer wants nothing less than a sharp image so the choice of a camera is nothing to gamble with. There are many reasons as to why you would want to narrow down your choices to a DSLR camera than to most of the compact digital cameras available today. Your digital photography work has to be at its best in order to attract more clients. Now that inexpensive or basic digital camera choices are available and almost everyone interested has one, professionals have to offer digital photo services with distinctive quality. That of course means acquiring the right camera even if it has to be expensive lest your work will not convince clients why they shouldn’t do it themselves and save their money.
Although a DSLR camera only a few years back would have been very expensive and only useful in taking stills, the prices have considerably gone down while the performance has improved to include high definition video capabilities. This has attracted independent filmmakers who only know better that even if compact digital cameras can be cheaper in most cases, finding the best required for their work will be even more expensive than DSLRs. As far as digital camera choices go, mechanics have proved better than electronics. While you manually control shutter in DSLR cameras to instantly allow light to reach the sensor, compact cameras have their sensors electronically activated and the truth is it doesn’t happen fast enough to suit requirements in professional photography work.
In addition to the sensor in a DSLR camera being mechanically activated, it is also bigger and that means more light which adds to the sharpness of images captured. It partly explains why such a camera will still manage to take quality shots in areas with less light even without the need to use flash light. Given that most compact digital cameras built for more portability are half the size of the smallest DSLR, their sensors are also small and that affects the sharpness of images. Even if the compacts have the capability to achieve more and smaller pixels, there will not be enough light on each of those pixels. Certainly the rules of physics remain unchanged and it is therefore the quality of the pixels that matters. There are also more choices of lenses with any DSLR and you only need the right one for each shot you want to take. More control and more accessories translate to better results.
