During the intermediate process in which the first digital cameras evolved into the DSLR, models emerged possessing characteristics of both and that before the acceptance of consumers, continued to modernize on its own line of development.
The “Bridge” digital compact cameras are essentially, but in physical appearance, are very similar to DSLR. These teams include in their controls and functions the same basic operational advantages of digital SLR models, but corresponding to their commercial characteristics, also have automated ways to facilitate maximum exposure, almost to the level of a “point and shoot”.
A Bridge camera offers consumers the possibility of having a team of appearance and semi-professional quality for a low cost, without having also faced complications involving interchangeable lenses, advanced operations shutter, calculations optimized exposure, decisions selective focus and other advanced features of the DSLR’s.
An important difference of the Bridge and DSLR’s cameras, is that the first use photo-sensors smaller and not have a shutter mechanism involving filter-mirrors.
These teams have won the popular name “Cameras Superzoom”, “Mega Zoom” and “Power Zoom” with powerful magnifications ranging from 30 to 50x and although the integrated objectives have the great disadvantage of not being able to offer maximum apertures, They are extremely attractive for lovers of distant observation.
The equivalence of the hyper-angular objectives of focal lengths (24mm) to Tele great power (1000mm), offering wide possibilities photographer framing and composition to face any situation in the field.
The Bridge cameras are much lighter than DSLR, mainly due to the size of the elements of its objectives and absent some mechanisms to achieve Reflex display. This point is important and should be clear that a Bridge camera does not offer the same optical quality for recording and preview the image a DSLR, regardless of their qualities, bid the same definition in terms of megapixels.
Why? Mainly for three reasons
Another important point to consider is that the new CSC systems, also known as “Mirrorless” for not having a system Reflex display, do not replace or try to compete with Bridge cameras as these offer the same advanced advantages interchangeable lens that DSLR and compete with the latter in the dimensions and quality of registration of their photo-sensors.
If you are excited to acquire a Bridge camera, I recommend that even its most attractive feature is the magnifying power of the zoom, also compare the dimensions and resolution of the photo-sensor, and the maximum brightness that allows the lens as these factors greatly influence the quality of the images.
