When you begin to as yourself: "What camera should I buy," it won't take you long to discover that any one time there are probably over 100 different models of camera to choose from.
Unlike when buying a car, you can't just go for your favourite colour, as cameras tend, in the main, to be either black or silver.
Like cars though, there are different shapes and models designed specifically for particular tasks, for fun days out and for the ‘serious' driver. To avoid some of the confusion I've broken down the main considerations so you can ask yourself all the important questions. Then, as if by magic, you'll come away with a camera that is going to make you very happy for a long time.
What camera to buy: Camera types
The first thing you'll notice is that cameras have a number of different basic shapes.
The smallest ones, that have a lens which doesn't come off the body, are called ‘compact' cameras.
Most compact cameras are designed to be used by people who ‘point-and-shoot' and who like the camera to do all the hard work.
Compact system cameras
A new type of camera is what is called the ‘compact system' camera - the ‘system' bit meaning that there is a range of lenses to choose from as well as accessories such as flash guns.
These are still small cameras, and they are still designed to do all the work, but they also allow a lot of flexibility and control.
The biggest and most complex cameras on the shelves are called DSLRs (digital single lens reflex). These cameras have a massive collection of lenses to choose from, as well as endless accessories.
While you can use them in point and shoot mode - and many people do - they are really designed for photographers who want to take control of every aspect of the way the picture is taken - it's brightness, how much is in focus, the way colours are displayed and the way movement is shown.
Although you don't have to carry more than one lens you have the opportunity to do so, and with the right kit there is no subject that you won't be able to face.
Somewhere between the DSLR and the compact camera is something called a ‘bridge' camera. These look a bit like a DSLR, but are smaller and their lens is not interchangeable. They tend to have extremely long lenses though, and can cover a wide range of situations. They are easy to use and are highly portable.
What camera to buy: Weight and portabilityIt is important to be realistic about how serious you are going to take your photography.
Carting a big and heavy camera is a commitment and an inconvenience, and unless you are very serious about your photography you will end up leaving it at home and wishing you'd bought something a bit easier to carry. This really is a critical factor, so make sure you go to a camera shop to pick the thing up and feel it in your hand before you buy - just to ensure you are happy with the weight and feel.
The size and weight of a camera is not directly proportional to the quality of pictures you will take with it, so don't be thinking bigger is better.
What camera to buy: Sensor size and pixelsDigital cameras record images on what is called a ‘sensor' - it's a bit like a piece of electric film.
Tiny elements, called pixels, on that sensor pick up the details of whatever you are photographing.
You might think that the more pixels the sensor uses the more detail it will be able to record, and in theory you'd be right. In real life though that is only part of the story. More pixels does not always mean better pictures, as camera engineers have to balance the number of pixels with how small those pixels have to be made to fit on the sensor.
Small pixels are like small hi-fi speakers - they can be a bit tinny. In general, compact cameras use very small sensors, and very small pixels. DSLRs use larger sensors, and so the pixels don't have to be made quite so small.
If you are buying a DSLR or compact system camera look for a model that has anything between 12 and 38 million pixels; in a compact or a bridge camera go for between 10 and 14 million pixels for good quality images.
What camera to buy: Zoom and lens range
Whatever camera you are looking at it will have a set range of lenses or zoom settings it can be used at. If it is a compact camera you have to live with what it comes with - so make sure it covers everything you will want to use it for.
The numbers on the box don't mean anything, and ‘10x zoom' only means the longest setting is 10x longer than the widest, so you need to look through the camera and see exactly what those settings and numbers translate to in real life.
If you are thinking about buying a DSLR or a compact system camera take time to see what lenses are on offer for that model and to see how much they cost to buy. It's no good buying the body and then discovering that you can't afford that long lens you want.
