Mirrorless cameras have become hugely popular in recent years. This is thanks to the fact that they keep the big sensors and interchangeable lenses of DSLR cameras, but ditch the mirror mechanism, allowing camera manufacturers to produce smaller and lighter, and often simpler cameras. 

Mirrorless cameras are also known as compact system cameras or CSCs, and there's now never been more choice, with a model to suit everyone. From simple to use entry-level models to sophisticated full-frame monsters to rival the very best DSLRs, there's bound to be a camera to suit your needs.
