Hot on the heels of the RX100 Mark III, Sony has announced its successor, the
RX100 Mark IV. Featuring more megapickles, a faster lens, and an all new
imaging pipeline, the RX100 Mark IV is, according to Sony marketing
literature*, “The best compact we’ve ever made this week.”
Sony engineers have been working for days improving upon the already very
good RX100 Mark III, and their hard work has paid off–the Mark IV is a
worthy successor to the RX100 Mark III in nearly every way, and owners of the
Mark III will be sorely tempted to upgrade. Here’s a handy chart detailing
the differences between the RX100 Mark III and RX100 Mark IV:
