Are you thinking of buying a digital camera? Maybe your old camera has stopped working or maybe you just want to get a better model, it really doesn’t matter, what’s important is that you understand what you are buying, so you can get the best possible camera for yourself at the best possible price. Below I will give you a list of the most important things you need to know and look out for before you buy your digital camera.

The number of megapixels the digital camera is capable of:

Generally speaking, the more megapixels a digital camera has the better quality photos it will be able to produce. It is true that with the higher end cameras or 8 to 12 megapixels, the quality of the digital cameras lenses will also play an important role, but for digital cameras of 6 and below megapixels, the number of megapixels is generally the most important factor in the quality of the digital pictures it produces.

When comparing digital cameras by the number of megapixels they are capable of, you will need to look closely at the small print on the digital camera or in the digital cameras manual. You may find that the camera is in reality capable of less megapixels then it leads you to believe.

Here’s what I mean, it is normal for digital cameras to have the number of megapixels they are capable of printed on them in big print, however quite often you will also find printed in relatively small print underneath the big print something like, five megapixels software enhanced to six megapixels. This will never be the same as a true six megapixel camera and will not be capable of the same quality as a true six megapixel camera would.

2. Zoom:

How much zoom your digital camera should have is really going to depend on the sort of use you give your camera, so only you can make this decision. However it’s important to remember that the more zoom you have the more you are going to be able to do with your camera.

Most digital cameras come with two different types of zoom, digital zoom and optical zoom. With digital zoom the more you zoom in, the more the total number of pixels in the image will decrease resulting in a considerable loss of quality. With optical zoom the number of pixels in the image stays the same because the camera will make use of its lenses to make the area you are focusing on bigger thus not losing quality.

Here too many digital camera manufacturers will try to mislead buyers by stating the digital zoom in big letters, but only revealing that it is in fact digital zoom in small print underneath.

Personally digital zoom isn’t of much use at all! You see, it’s much better to digitally make your image bigger at home on your computer, since by doing so you will be able to see how much picture quality you will have to give up and you will just have so much more control. Not to mention the fact that you will still have your original photograph at full quality.

A digital camera’s powersupply

The powersupply is something greatly ignored when people buy digital cameras. People just don’t consider it, yet when you think about it having a reliable power source for your digital camera is vital to make sure you don’t ever run out of power right when you need your digital camera most.

With the lower end cheaper more commercial digital cameras AA and AAA rechargeable batteries are quite common. In recent years these batteries have come down considerably in price so this isn’t such a bad thing. You just have to remember to keep several sets charged and ready to go at all times.

Specially made lithium battery packs are normally used in the higher end digital cameras. Because of the fact these battery packs are specifically made for the cameras in question they are also normally considerably more expensive.

Since these batteries are normally somewhat more expensive you will also want to take this into account when comparing price on each different camera model. You do normally get the added advantage of a longer period of usage of the digital camera when using these battery packs.

A few digital cameras have the capability of being able to take both their own specific battery pack and normal AA or AAA rechargeable batteries you can find at any supermarket.

If you take into account everything mentioned above when you compare digital cameras, you should have no problem in choosing a good camera for your usage. Also remember to check out on-line reviews as they will help you compare each camera.

Checking out on-line reviews can become even more important when you’re looking to buy professional digital cameras, since lenses and other specifications for the cameras can make a lot of difference at this level.
