Which Digital Camera Do I Choose

Most of today’s digital cameras are capable of producing great quality results. Even the less expensive seem to offer a wide range of controls.

Cameras largely fall into three groups. The simple point-and-shoot compact is probably best for a beginner. Next is the more expensive SLR (Single Lens Reflex) which will have a greater resolution and usually a zoom lens. The top of the range professional cameras will offer even more resolution, more flexible camera and image controls and better quality lenses.

Cameras with optical see through viewfinders provide a small but adequate view. Many, even the less expensive cameras, have a liquid crystal display (LCD). The larger screen is easier to use and often flips out which is useful for awkward angles.

The more expensive the camera, the more pixels it will generally have. So what is a pixel and how many do I need? A pixel is a picture’s element. The more you have the greater the resolution – the capability for recording greater detail. The image sensor is made up of individual pixels, so an 8 megapixel sensor will have 8 million pixels or picture elements.

For normal size prints and for web use 3-5 megapixels are ample, but for more professional use 8 or more megagpixels are needed. Remember that the number of pixels doesn’t guarantee good image quality – a lot depends on the quality of the lens. That’s why the more expensive cameras have more pixels and high quality lenses. As with many things, the final quality is only as good as the weakest component.

Digital cameras store images on memory cards. The cards supplied with the camera are usually inadequate – good for only a handful of images. You will need to buy a card with a reasonable amount of memory. Often the manufacturer will give an indication of the number of images a card will hold.

It’s important that your camera feels right. Be comfortable with it. Don’t go overboard when buying your first camera. If all you need is a point-and-shoot compact for the occasional holiday snap, don’t spend a fortune. On the other hand if you are going to get serious, then think about how your camera system will grow with attachments like flash, tripod and filters etc. And don’t forget – have fun!
