The pictures from the latest generation of cameras - and that includes DSLRs and dedicated video camcorders - are stunning. No one expected to be able to get pictures this good for so little money.
The quality of the images is all the more surprising when you realise how much they’re being compressed to fit into the internal storage in the cameras.
