On this page, I collect information about Sony RX100 M1 firmware updates.
So far, the following firmware updates were published:
While the Sony RX100 was released in 2012, it took until early 2015 before the first - and probably - only firmware update for this camera was released. In addition, while the improvement may be useful, many issues that plague the camera were not fixed - and many chances for improvement were left out.
Contrary to Ricoh, Sony does not seem to improve its cameras over time and prefers to add new models, instead, even though the old models are still being sold. Not very satisfying for users...
On the following pages, you can find links to firmware updates for the Sony RX100 M1 (actually, there is just one update):
