I'm looking at buying a new super zoom camera (currently use Panasonic Lumix FZ38) and have been thinking of buying the Sony Cyber-Shot HX200V which seems well reviewed and states it has 30 x Optical zoom.
However I've just read a review of the Sony Cyber-Shot RX100 which looks a great camera and really compact. However this says it just has a 3.6 Optical Zoom. Can that be right? Is it really so much worse than the HX200V in terms of zoom or are they measuring it in different ways? Even though it only says it is 3.6 optical zoom it says it has a 28-100mm f/1.8 Carl Zeiss zoom lens which soudns quite impressive.

Can anyone help??
