Many people often get confused before buying a digital camera thinking which one is better for them. You must keep some points in mind before going to buy a digital camera to avoid such confusions.
At first you should set your mind about what is the purpose of buying it, what is your budget and what are the features the camera should have. After getting confirmed and determined about these look out for other features.
Resolution is one of the key factor that should be checked before buying the camera. The more the resolution is the better will be the image quality. The resolution delivers you the picture in depth. So the more is the resolution, the more detailed picture you will get which makes the picture more lively.
Then check the zoom system of the camera. There are two types of camera zoom. Digital zoom and Optical zoom. But here definitely optical zoom is a lot better. So focus for on optical zoom. The more optical zoom camera has you will be able to zoom on more distant object without losing the quality. Always look for a lens that contains a fairly bright maximum aperture.
If you use the camera for professional purpose then you don't have the option to consider about the size of the camera. Most of the professional cameras are big in size than non-professional digital camera. But if you use the camera for just capturing your daily personal and fun time pics then you have a option to buy the ultra-portable camera. This type of camera can be fitted in your pocket easily although it's expensive and difficult to use for some people.
Camera screen is another factor to be checked before buying. It should have minimum 3" LCD display having all option to edit the photo immediately after captured. In screen also should have the zoom option to zoom the captured photo at a certain level to check the depth of the photo and transparency. In the camera there also should have the different shooting modes such as portrait mode, night vision mode, landscape mode, sports mode etc. These options must be checked before buying a camera. The more features the camera has the more functionality it will provide.
Very often we capture some pictures that come blurry. It happens because of shutter speed. Standard shutter speed range is 1/1000s, 1/500s, 1/250s. Choose the camera that has the more compression and image formats. Cameras having at least three image formats should be prioritized.
