In our time, a huge selection of digitalcameras is simply amazing. However, many buyers still do not have a clue as to what criteria to follow when choosing this technique, which is necessary in every family. Almost everyone has ever heard about megapixels, matrix, zoom, but not everyone knows what they really are. That's why some buyers make mistakes in choosing a digital camera, succumbing to the tricks of advertising and the persuasion of sellers. Let's talk about how to choose a digital camera.

Choose a digital camera: options

Resolution

This parameter is defined in megapixels. Many people consider the number of megapixels to be the main indicator when choosing a camera. Pixel is the smallest element of the matrix of a digital camera. The pixel has a certain color and is part of the image. A million pixels is a megapixel. The more the number of pixels, the better the picture. The resolution of the image is measured in the number of pixels along the vertical and horizontal lines. The higher the numbers, the better the picture.

A large number of megapixels does notmeans that the camera is very good, it only says that the resolution of the photos will be maximum, and the quality of the picture depends on other parameters.

If you want to take pictures for a familyarchive, then you will have enough camera with 3 megapixels. For high-quality images on A4 paper, you need a camera with 5 megapixels. If you want to get small-sized photo cards, choose a camera with 7 megapixels. 12 megapixels at the moment is the largest number of pixels in a digital camera.

Matrix

The quality of the matrix is ​​of great importance in the questioncamera selection. This device is a plate that, due to the content of photosensitive elements, forms an image. How to choose a digital camera with a good matrix? The larger the matrix, the better the image. The sensitivity of the matrix is ​​measured in ISO. Do not select a camera if its ISO reading is less than 100.

There is a way thatcheck the quality of the matrix. First take a couple of shots in a row, then close the lens and remove the completely black background. Maximize the last picture and study it. If you find white dots on a black background, do not purchase this camera.

Aperture of the lens

The parameter of the luminosity depends on how muchthe aperture of the lens will open, and this will affect the amount of light penetrating the inside of the lens. This parameter is very important when shooting indoors, from a long distance or at night. The aperture is denoted as f / number (f / 4.0). The smaller the number, the greater the aperture and, consequently, the possibilities for shooting increase.

Zoom

Zoom is the difference between the smallest andthe largest focal length. Many are confident that the more the focal length of the lens, the better the pictures are obtained. It's a delusion. With a large focal length, there is often a problem when the frame does not contain everything that you want to shoot. The smallest focal length should not exceed 24 mm, and the largest focal length should not be less than 85 mm. Most digital cameras have a three-time zoom of 30x90.

The zoom can be optical and digital.

  • Digital zoom stretches the picture and it loses its quality.
  • Optical zoom magnifies the image by changing the focal length of the lens.

When choosing a camera, give preference to optical zoom.

Lens Quality

The quality of the lens does not indicate in the instructions for digital cameras. Therefore, when choosing a camera, refer to the reviews of users of digital cameras on the forums of amateur photographers.

How to choose the right digital camera: the camera class

There are three groups of digital cameras: amateur, semi-professional and professional. A professional camera needs to purchase additional equipment (professional lenses, tripods, flashes, etc.).

Do not immediately buy expensiveprofessional camera. Hardly you can get on with him. Try to start with an amateur digital camera of good quality, and then go to semi-professional. If the creation of pictures attracts you and you master the basic rules of creating good photos, take a closer look at the acquisition of a professional camera.

Which digital camera to choose

Firms that produce digital photo equipment,can be divided into two groups. The first group includes highly specialized companies that produce only cameras (Canon, Nikon, Olympus, Fuji, Kodak). The second group includes firms that produce various electronic equipment (Sony, Samsung, Panasonic).

Professional photographers advise to stoptheir choice on the manufacturers of the first group, but this does not mean that the products of the producers of the second group are not able to compete with the world leaders in the creation of photographic equipment. This suggests that you need to focus, not based on the name of the manufacturer, but on the characteristics of the camera.

Memory card

Usually a digital camera is attached to the digital cameramemory. It is worth paying attention to the volume of the card, often it is quite small and therefore it is necessary to purchase an additional memory card with the optimal volume.

Selecting a memory card depends on the settingsdigital camera, shooting frequency, format and image resolution. Do not save on a memory card. So you risk to overpay in the future, buying another card with a large volume. To avoid memory problems, do not select a memory card that is less than 1 GB in size.

Of great importance is the type of memory card. You can find universal memory cards that can work on different models of cameras, and cards that work with a certain brand. Such cards as Compact Flash and Secure Digital have compatibility with cameras from different companies. And such memory cards as Memory Stick and xD-card are used in cameras of certain brands (Sony, Olympus). When buying a memory card, do not forget to check it for compatibility with your digital camera.

Food

Usually digital cameras are powered byfinger batteries. You can buy such batteries anywhere. Some cameras use lithium batteries. Such batteries can not be charged without an outlet. Before buying a battery, check the time of its operation, and also it will be useful to take an online survey of users of digital cameras.

Digital Camera Test

In order to determine exactly whicha digital camera is better to choose, it is necessary to test it. Hold the camera in your hands, take a couple of pictures in different modes, take a closer look at the sharpness and clarity of the picture in motion, pay attention to the speed of shooting, find out about all the functions of the device. Some stores provide the service of printing photos on the spot, so you can evaluate the quality of the picture. Also a significant criterion is comfort when using the camera. Make sure that you are comfortable to hold and carry the camera, the buttons are pressed easily and there are no obstacles before using all the possibilities of the camera.
