Black Friday bargains have arrived. For today only, Amazon has a great deal on the Sony RX100 Mark IV high-end compact, at just £575 (save £425) - see the deal here.

Well known as one of the best pro-spec compact cameras going, the RX100 series crams a viewfinder, tilt-angle screen and larger 1-inch sensor inside its pocketable body.

Be quick, though, as this deal is only available until the end of 24 November, or until the stock is gone. That's the way Black Friday goes.
