That's the sort of news I wanted to hear At such a close working distance, 40% extra would be amazing.

Thank you

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.

Evening all (well, it is here) Forgive me for what could be an obvious question, but my knowledge of optics is a little lacking. I have just acquired a Saga +25 macro lens (as well as a +10) for use with a Sony RX100 (MK 1). I have some very small targets in mind I have tried this out on the coffee table, and to achieve focus, the port is resting on the table. Naturally, I can see this being an issue UW - I am not particularly enthused by the prospect of squashing a nudibranch or pygmy seahorse or damaging their habitat. My question is: How much if any, additional working distance will I gain by being underwater? I don't have access to a pool to test, although I guess I could always have a go in the bath! Thanks in advance Sean

They are not native to the area and as such have no natural predators. Just google 'Cozumel Lionfish hunt'

That is just stunning! Loftus, would you mind if I cross-posted the image to another dive forum (obviously I would include a link to this thread).

No, it doesn't. And I didn't need it anyway. My camera had the dioptre adjusted on land when I first bought it, and I haven't touched it since, and it has been in the Ikelite housing with and without the Inon viewfinder. I personally do not see the benefit in a dioptre adjustment on a viewfinder, unless it is a rental housing.

New wife?

Not a great answer to your question, but I too have the Ikelite housing and struggled with the standard viewfinder. I have fitted an Inon 45 degree viewfinder, using an adaptor from UWCameraStuff It's a revelation, the image is big and bright, has full coverage, and actually allows me to compose, rather than having to guess. Not the cheapest solution, but a lot cheaper than upgrading housings!

A friend bought the ISS4000 strobe and ebayed it after 2 dives, the beam angle is far too narrow for anything except macro Sean

I went at Christmas and had my visa within 3 minutes of walking into the hall There were quite a few empty booths, with the majority of people all using one booth as they were on a package
