Different reviews on various digital cameras will recommend at least 3 megapixels to snap the best photos but still low end digital cameras of 2 megapixels can work greatly.  If pictures look good on your computer or laptop, they should also look good when printed and more gorgeous when developed.

Many digital camera suppliers give simple information and perhaps a buyer’s guide to furnish them with all the necessary details and tips to getting the right tools.  As soon as you decide what you will be doing with your digital cameras, you’ll save a lot of time in the selection process.  The tips below are guidelines on all the key things a buyer should look at while choosing best cameras:

1. Megapixels

There is lots of perplexing information about megapixels in many digital camera buying guides.  Digital images are composed of small dots known as pixels and 1 Million pixels equal to 1 megapixel.  The greater the number of pixels, the sharper the quality of images generated.  Many digital cameras in the market range from 1 to 11 megapixels but this doesn’t mean that cameras with lower megapixels do not capture great images.

Higher megapixel cameras are best for enlargements; the more the number of pixels, the higher the price of the camera.  As the level of megapixels goes up, cameras have more add-ons and controls.

2. The Zoom feature

The zoom feature allows users to change between close up shots and wide angle shots.  Various digital cameras feature either a digital zoom or an optical zoom.  Optical zoom is deemed to produce pictures of a higher quality while digital zoom reduces the resolution of the shot images.  Digital cameras with the two features are the best deal.

3. Memory size

Digital cameras use memories to store pictures as opposed to films for ordinary cameras.  The memory can be used again unlike the films.  Digital camera memories come in two different types; the internal memory or a removable memory – also known as the memory cards.

A bigger number of the best digital cameras use removable memory cards while low end cameras use the in-built/internal memories.  Memory cards allow users to easily upgrade to larger memories or swap what is already contained and create more room for additional data.  CompactFlash is the best type of memory card; others include SmartMedia, Sony, CompactFlash II, IBM Microdrives and MultiMediaCards.

4. Battery life

Digital cameras eat up power quickly and more if they are using LCD.  Chargeable batteries are the best; whether Lithium Ion or Nickel Hydride.  Lithium Ion batteries are small, long lasting but more expensive compared to Nickel Hydride ones.

Many digital cameras are not packaged with an AC adapter and there is a great need to have one.
