Guideline to Purchase a Digital Camera

Digital cameras are popular nowadays. How to choose the right digital camera for yourself? Excepting the CCD pixels, resolution, there are some Points about which you need to think.
How to choose lens zoom range?
A zoom lens has a variable focal length. The focal length determines the magnification of the lens. A short focal length is a wide-angle lens, great for taking in large vistas. A long focal length is a telephoto lens, allowing you to get a tight photo of a distant object or person. A zoom lens lets you combine both of these and everything in between into a single adjustable lens. If a camera has a 3X zoom, it means that the longest focal length is 3 times the shortest. You’d better consider the shooting range which you frequently used when you want to purchase a camera.
The digital camera with  the fixed focal length lens features in easy-operating, compact and low price although  its lens without the   optical zoom capability. If you just want to use the camera to shoot the scenes of life, portrait figures, or the commemorative photo in your travel, you can choose this one. DDC-MX650 is really the top choice for you. Mx 650 is with the 6.36M CCD, and its max resolution is 3648×2736. Usually, the camera can basically meet the quality of the normal life photo. 
  For most photography enthusiasts, the cameras with 3X optical zoom are nice. But they are in higher price. At present the flagship products of major camera manufacturer are the 3x optical zoom models. Like Sony’s S75, S85, Olympus’ C50, C400 and Canon’s PowerShot G2. GlobeOffer’s DC-t750, dx650, and DV-5120 are also hot selling. If you like long-distance shooting objects, this time you need a greater zoom range of lenses.
Lens aperture
The aperture of a lens is its maximum opening. The bigger the aperture, the more light is gathered, and the less light you need to take a good photo. This is the most overlooked lens specification, but it very important, especially if you like to take photos indoors without flash or from a reasonable distance. Basically? F2.8 is nice. Many common cameras like Olympus’ C50, GlobeOffer’s DC-T750 is with F2.8.
  about the budget
 Many people like purchasing cameras in brand name. Although they seem have quality warranty. But usually these cameras are in high price. More and more people like choosing cameras on online camera shops like GlobeOffer. These cameras are also in high performance and at least under one year quality warranty. Moreover, they are in lower charming price, in various styles.  Just a few clicks, you can save you many time and money comparing with buying a camera in a supermarket.
 All in all, the above are some experiences of me to buy a digital camera. Hope you can get a little help from it.
