Most people when buying a digital camera really don't know what to look out for. Let's face it, most of us are not particularly tech savvy, so we have to rely upon what other supposedly tech savvy people advise us on. It really is essential that you know what you're buying when it comes to buying a digital camera, so in this article we will discuss the most important factors to lookout for and what to avoid.
A digital camera's megapixels
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.
What many digital camera manufacturers do is to print on the camera or in their manuals say six megapixels in big writing, but underneath there's writing where they will put something like five megapixels enhanced to six using software. If the camera states something along these lines the camera is not truly six megapixels at all. If the camera has to use software to enhance its number of megapixels it will not be as good as a true six megapixel camera.
2. Zoom:
You're going to have to decide just how much zoom your camera will need, for this think about the type of photography you want to take with the camera, if a lot of long-distance photos are going to be taken, obviously more zoom will be very useful.
There are two kinds of zoom, optical and digital. Optical zoom zooms in using lenses within the camera, so there will be no quality lost. Where as digital zoom on the other hand will simply make your pictures bigger and so will lose you are lot of picture quality.
Again just like with the megapixels of a digital camera, the manufacturers often try to mislead you by using big wording stating how much digital zoom the digital camera has but only mention that the zoom is in fact digital in small print.
Personally I never use digital zoom. This is because I would much rather take my picture at full quality and then when I'm at home make use of my PC to make the image larger. This way it is possible to see in real time how much visual quality you will be giving up and of course you will still have the original photo at full quality.
The powersupply for your digital camera:
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.
AA and AAA batteries are the most common method used to power the lower end digital cameras. In many ways having this kind can be a good thing in that these batteries are cheap and easily replaceable at anytime.
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.
Some digital cameras can take both normal batteries and their own specific battery pack. This could, as I'm sure you can imagine, be a pretty cool feature since it will give you full control.
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.
