So many different types of digital cameras available, so which digital camera to buy

Great image quality from digital cameras is achieved via a combination of factors, e.g the lens quality, image processing, sensor size etc... The problem is you can't judge a lens or the camera's image processing just from looking at the camera.

But you can get a pretty good idea of the sensor's size and image quality just by understanding the different types of digital cameras and knowing which category the camera falls into.

This video looks at smartphones, compact cameras, mirrorless (Compact System cameras), and DSLR's and should provide a good understanding of camera choices and help to identify which camera is best for you.
