I logged on tonight expecting to order a Sony DSC RX100 .... initially put off as housing were almost twice price of camera, now that there are much more price friendly housing available. (less than 30% of camera price)
I was surprised to see that Sony have released a new version of the camera - DSC RX100 II
Tilting LCD, Hot shoe and new menus - may not be of much use to divers, but the backlit sensor is quoted as giving a full stop gain, and also a 40% increase in Low Light sensitivity, and greatly increased focus speed in Low Light .... now that is of interest.
Already rated very highly as the market leader in compact with it's 1" sensor ... this could now make it a very good choice for divers who don't want to go DSLR route.
Was enough to make me hold off for a couple of weeks for prices to settle.
