With the exception of the high-end professional digital cameras of 12 plus megapixels, the number of megapixels a digital camera is capable of generally speaking is the most important quality factor when it comes to how good your digital photos will come out. In the case of the high-end digital cameras the lenses themselves will also play a very important part.
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.
For example some digital cameras will have in big print on the camera and or in its documentation say six megapixels, but underneath in small print it will say something like five megapixels enhanced to six using software. Basically this means that the camera is really only capable of five megapixels but the software in the camera will attempt to enhance the quality of the photos to six megapixels, this will never be as good as a true six megapixel camera.
How much zoom do you need?
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. 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.
In my opinion digital zoom is about as useful as mud, I’d much rather not use digital zoom and instead digitally enlarged the picture at home on my PC. This way I would be able to see exactly how much picture quality I would be losing and I would still have the original picture 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.
Some lower end and most of the higher end digital cameras will only accept their own powersupply specifically made for that camera. These powersupplys are normally Lithium batteries and can be quite expensive. They will generally give you the advantage of lasting longer, however it is still wise to have at least one spare pack charged and ready to go with you at all times. When considering price on different cameras remember to take into account the added price for battery packs in the future.
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.
