In Topic: Effect on focus distance of being underwater

That's the sort of news I wanted to hear :)

At such a close working distance, 40% extra would be amazing.


On the sony RX100 mark 2 you will get a working distance increase of about 1.4 so you should be OK.

I have just asked Saga, who came back to me very quickly.
"Under the water you will have more distance, 33%, anyway that lens is to make very small motives and you have to get very close."
 
Other items I have read have also said that "In water the minimum focus distance increases and so does magnification so performance is all in all the same"

I need to do some reading up on optical theory.

Hmm, not what I wanted to hear really. If that's the case, then the camera will be trying to focus inside the lens.
