The difference between cheap and expensive cameras

The difference between cheap and expensive cameras

How so cheap?
Manufacturers cut not the sensors that they stop the cheap cameras, so you can use inexpensive equipment also decent photos. They have cut the number of megapixels and above the equipment, but given the quality, you will see little difference. Expensive cameras have on average more megapixels and a range of tele 12x or greater and sometimes you even HD movies. Cheap cameras do not support more than what you least expected of a camera. That is at least enough for the tasks for which a camera you use most often.

Light Conditions
Under good lighting conditions, shooting almost every digital camera's endearing. Only in the dark, with large differences in contrast between light and darkness or poor lighting, problems are visible. Poor light conditions can often remove a flash, just a flash is not always desirable. In such cases you have the light sensitivity of the camera, called the ISO speed, increase. The higher you set this value, the lighter parts of the image are dark. This does cut the noise, and undesirable artifacts appear in the photos. In more expensive cameras are better image sensors, so image quality is better, but not much better than what you based on the price difference should be expected.

Advantages and disadvantages
Many inexpensive devices you have many automatic functions allowing the photographs almost always succeed. A disadvantage is that the battery is less expensive compared to more expensive devices. This is because expensive devices have larger enclosures, which offer more room for larger batteries that last longer. As for the warranty period, manuals and hotline prices make manufacturers no difference between expensive and cheap devices.

Where do you primarily look for when buying a camera
Megapixels: Many consumers think that more megapixels lead to better and sharper pictures, but it is not. Nobody has more than eight megapixels needed. The more megapixels on a sensor there are, the worse the image quality and sensitivity. If your photos to print on A4-size, is a camera with six megapixels enough.

Mega: The more expensive cameras you sometimes see a 18x or 20x zoom. In practice, you got just what if the lighting conditions are favorable. The more you zoom in, you need more light. Moreover megazoom cameras big and they fit in a breast pocket. For most images a 3x zoom is more than enough.

Memory: Most manufacturers use SD cards. This is convenient, because then you are not required to buy new memory cards s all you buy another camera. SD cards are not expensive. For 10 euros you have an 8GB card.

Video recordings: With almost every digital camera can record movies. Note that at least one supports video resolution of 640x480 pixels.

Operation: Try the camera in the store and feel that good in the hand. Take a few pictures and make sure the camera has a short shutter lag. This avoids the issue has disappeared from view before the photo was shot.
