What do I need to know to buy a memory card for the camera?

Choose memory card to buy for the camera is not simply knowing the type, go to the store and buy one of the maximum possible capacity. Lol It is necessary to know what offers every format, the importance of the size, as well as speed and some extras that can be included.

If you are thinking to buy a new memory card n below we show you everything you should know about memory cards for camera.

Memory format

There are different formats or types of memory. We have cards Compact Flash, Secure Digital (SD), Micro SD, Mini SD, Memory Sticks Pro Duo. (see http://www.ablogtophone.com/2016/04/18/asus-memo-pad-hd7-a-cheap-tablet/).. Each with its own advantages and disadvantages.

Of course, that our camera can not make use of all. Each manufacturer committed to a type, being currently the SD format most widespread. Therefore, the first thing to do is to consult the documentation of our camera and see what type of memory card used.

In some cases that even us option to make use of two models. In those cases we’ll see later that pick.

Storage capacity

Choose the storage capacity for our new memory card is not simply opt for the maximum capacity that supports the camera. To avoid mistakes, we will have to see the camera documentation to know what capacity supports.

Once we know the supported maximum capacity, it is important to know how much is each photo that captures the camera. Not all cameras, even with the same megapixel resolution, produce files with the same size. It affects the degree of compression that is applied to the .jpg file so as if it allows much or not to shoot in RAW.

Knowing the number of photos in highest quality that allows to store 1GB in our camera, we will decide the capacity we need for our applications. It is interesting to know also whether we are users who made many photos in each session, or if they are just a few snapshots.

Known all the above data the last point is rating if you buy a card with the capacity that we need or two with half capacity. This is something that depends on each user. There are those who prefer two cards so that, where it could fail one, let us not lose the pictures. Then those who opt for a single, as being forced to change card in a sporting, social event or trip could do that they lost the opportunity to photograph an unrepeatable moment.

Transfer speed

It is an important point. The speed that is able to write or read data stored is not the same on all cards. It is what is known as a class. There are four types:

  • Class 2, works at 2 MB/s with a maximum of 8 MB/s
  • Class 4, runs at 4 MB/s with a maximum of 15 MB/s
  • Class 6, runs at 6 MB/s with a maximum of 20 MB/s
  • Class 10, operates at 10 MB/s with a maximum of 30 MB/s

The importance of speed is a function of the size of file that generates the camera, both in photos and video. Larger (capacity in MB) is the most important file is that it is fast.

A fast card will allow us to bursts of higher. For example, if our camera allows bursts of 6 shots per second but we use a slow card never not get that maximum. In addition, at the time of access to the data, as well as to pass them on to the computer it will take less time.

Finally, needless to say that for subjects of video it is very important to always have the maximum possible speed, and class 10, right now if we don’t want to suffer small jumps in the image.

Clamping concepts

Therefore, remember that buying a memory card new for camera is simple if we take into account the following aspects:

  • Check out the compatible memory type (CF, SD, MS Pro Duo,…)
  • Meet the supported maximum capacity
  • Choose the class (read/write speed), it is recommended to opt for a high class always

And what happened to the case in which we may use different formats in the same camera? If our camera allows, for example, make use of SD and CompactFlash cards are the ideal is to always use that offer better performance. In this case no doubt it would be the CompactFlash. Although it is an “older” card format, the new models allow higher read / write speeds which are ideal for squeezing the possibilities of the camera.
