Digital cameras on sale really vary in prices depending on the type and some other factors. However, as the quality of images from digital cameras improve they are becoming much more affordable and the sales are simply not surprising. Consumers are also becoming more comfortable with the whole idea of taking of photographs digitally.
Here, let us look at the various types of digital cameras
It does not matter whether you are shooting film or digital images. There are basically three types of cameras. There are point and shoot cameras, prosumer cameras and professional quality cameras.
1. Point and shoot cameras operate automatically - They do everything for you except for framing the subject. Exposure is decided by the camera as well as whether a flash is needed or not. All you need to do is to point and shoot. Point and shoot cameras are great for quick shots, self shots, and its small size will be appreciated during travel as you can easily carry them around anywhere you go. As mentioned several digital cameras such as the Lumix FX 500 includes special features and technologies, such as the anti-shake system as well as a touch screen interface. They have come a long way in this regard and many have a noticeable gap between pressing the shutter button to take a picture, and the image being recorded. If you've ever tried to take photos of fast moving objects, you will probably have noticed this. However, these cameras have a number of defects and many of them can be traced to the small sensor size in the bodies.
2. Prosumer Cameras - This camera is a step up from your typical point and shoot because it allows the photographer not only to shoot in a fully automatic mode but also to have control over various aspects of the exposure. They typically have various modes including portrait mode, a close-up mode, action mode, and landscape mode. Prosumer cameras feature an electronic or optical through-the-lens viewfinder that lets you evaluate and focus through the same lens used to take the picture. These cameras either have a good quality, fixed zoom lens, in the 8:1 to 10:1 magnification range that practically eliminate the need for removable lenses in the first place. They will have through-the-lens viewing or, at the low end, an electronic viewfinder. These cameras see through the lens but by means of an LCD screen.
Prosumer cameras are aimed at less demanding professionals in order to serve as backup cameras for them. It is also good for people who have photography as a serious hobby. However, the cameras also have their defects. For instance, cameras like the FZ range are very capable cameras but they have a large number of pixels on a relatively small sensor and as a result tend to suffer from noise, particularly at higher ISO levels.
Prosumer cameras are sometimes marketed as and confused with digital single-lens reflex (SLR) cameras since they look the same. The distinguishing characteristics are that prosumer cameras lack the mirror and reflex system of digital SLR's, have so far been always produced with only one single sealed, non-interchangeable, lens but accessory-wide angle or telephoto converters can be attached to the front of the sealed lens, can usually take movies, record audio and the scene composition is done with either the liquid crystal display or the electronic viewfinder (EVF). Digital SLR cameras use an optical viewfinder which is not only easier on the eye but also more accurate. Prosumer cameras fit that role in both function and nomenclature. First, they tend to look a bit more like D-SLRs, with larger bodies and bigger lenses.
Prosumer cameras are somehow a hybrid class, they are the best that manufacturer can offer below the DSLR. They are meant to be used by the advanced amateurs.
3. Professional Quality Cameras - Professional quality cameras are designed to be mounted on walls, ceiling brackets, buildings, indoors and outdoors. They are designed for quick and easy installation, must have utility and have to be easy to use and provide instant access to all adjustments. These cameras and lenses cost tens of thousands of dollars and they need to be maintained or replaced regularly and most range in price from $3,000 to $65,000, depending on features.
Professional cameras use use a glass prism to separate the light coming through the lens into its three primary colors. Then the light is captured by three different Charged- Coupled Devices (CCD's) . Professional cameras offer both features that will make a beginner's photos worse and features that most serious amateurs do not need. These cameras automatically control focus and exposure, guaranteeing that anything that is in the frame will come out in focus and competently exposed. Of course, these are cameras mostly available for professional photography and experts to use.
In a nut shell, when choosing a digital camera, you should take into account your basic needs and what you plan to use the camera for.
