So am I.

I had this misconception for a while myself. Then I played with my RX100, P300, and a borrowed T3i side by side. Given the same aperture and ISO, the exposures were the same, other than some minor metering differences.

Do you really understand what is ISO?

The larger sensor of the RX100 means it can achieve higher IQ and less nose at higher ISOs than the LX7 it has nothing to do with shutter speeds as you imagine.

What is being imagined? read below:

Between RX100 and LX7 for example, RX100's iso 280 IQ is about the same as LX7's ISO100. For a scene were  LX7 would use F1.4  1/50s iso 100, RX100 would use F1.8 1/50s, iso 165 to get the same exposure - RX100's image would have higher quality. Or the RX100 can do F1.8, 1/80s ISO 280, it would produce the same IQ as LX7 with 2/3 stop faster shutter speed.

These can be confusing concepts, please read about them before playing forum expert.

That is oxymoron isnt it? how do you learn if you dont talk about it?
