There are a lot of different things that you need to look for while purchasing a camera. Some of those things are resolution, optical zoom, digital zoom, LCD, viewfinder and flash. A good digital camera buying guide on the internet should be able to help you with all your needs. These things might seem irrelevant at first but they will definitely matter in the long run. Another important feature that you need to look for is warranty. The thing about warranty is that there are different types and protecting your camera investment is important.

Images are comprised of tiny dots that are called pixels. A combination of one million pixels is called one megapixel. The higher the number of megapixel the bigger you can print and for a good image you need a minimum of six megapixels. No need to worry though because most cameras that are available in the market offer more than ten megapixels. You can find a lot of good articles online at a digital camera buying guide website. The next thing to need to understand is optical zoom and how it compares to digital zoom.

A digital camera buying guide offers excellent comparisons between optical and digital zoom. Optical zoom is when the lens actually shifts from the sensor of the camera. For example let’s consider a camera with a minimum focal length of 18 millimeters. For such cameras an optical zoom of 3X or three times would be 54 millimeters. That’s why most DSLR cameras sell the basic lenses of 18 to 55 millimeters. Optical zoom is basically a physical magnification of the lens when it changes focal-length. Digital zoom is basically a digital magnification of the image that hits the sensor it’s not used very often. Optical zoom is always superior compared to digital zoom.

A digital camera buying guide is also a good way to find out about LCD and viewfinders. Digital compacts use LCDs to preview pictures whereas DSLRs use viewfinders to preview pictures. Now there has been a lot of ongoing debate about using LCDs and viewfinders to preview pictures. The fact is that true optical viewfinders are almost only found on DSLRs. The only small cameras that have am optical viewfinder mechanism are range finder cameras. These cameras offer you the portability of a compact and the image superiority of a DSLR but at a very expensive price and limited features.

Last but not the least, features and price. Features differ from camera to camera, so this can be decided only when you learn about what each feature is for. The most important thing that camera buying guide will talk about a price range. Sometimes the ideal camera is simply out of your budget and a compromise must be accepted. This will ultimately help you choose and some guides also help you choose the best camera for you by letting you compare models side by side.
