Lenses are always identified by their focal length. It’s not just a physical measurement, it’s an indication of the type of lens it is, for example, a wideangle lens, standard lens, telephoto and so on. In other words, the focal length of the lens gives you an indication of its angle of view. Or at […]

The advantage of interchangeable lens cameras like DSLRs and mirrorless cameras is that you can change lenses for different kinds of photography. There are many different types of lenses, often with specific names. Lenses are usually characterised or grouped by their focal length. It might be more useful to use their angle of view instead, […]
If all you want to do is take pictures and you don’t know much about cameras, the range of camera types on the market is bewildering. Even if you do know a bit about cameras, it’s not easy to weigh up one type against the other and make a decision about which to get. So […]

The larger the sensor size, the better (generally) the picture quality. Megapixels do confuse the issue somewhat because you can […]
