Thanks @Alex_Mustard , certainly seems like it would be useful for the type of shots I take locally (and for a forthcoming trip to Lembeh!!) The question I have is will it work with micro43? The Olympus 60mm macro is a nice lens and works very well, but it's a bit too long at 120mm equivalent, unless you are on quite small subjects. Switching to a ~30mm macro when I come across a weedie or Eastern Blue devil fish or even a red indian fish and other similar sized subjects would be perfect. I can't think of a reason it wouldn't work except perhaps I'm mostly working at f8-10.

Which flip adapter are you using? Is it the one for MWL-1?

One of my group (Mark Green) used it successfully with the 90mm on OM-1. And the 60mm is listed as a lens it works with on the Nauticam website (link below - list at bottom of the page)

My flip adapter is a standard double Nauticam one.

How did he like it with the 90mm? It would be nice to get a bit wider field of view with that lens at times (can't imagine even with the MFO-3 it would be a good choice for blackwater though!).

After all the nonsense published about the MFO-1 and subsequent before and after work showing not very much difference are there ANY with and without photos? I spent $500 or so on the MFO-1 and don't want to make another mistake.

We do lots of black water and using the 30 macro (either Oly or Pany) I seem to be close enough for anything I want to shoot.

I've ordered one, for me the attraction was having a 60mm and a 30mm macro on the same dive. In Sydney we have on the same dive Pygmy pipehorses which are about a 1/3- 1/2 life size+ subject for m43 and weedy sea dragons which are 300-400mm long so having a wider view with me seems worthwhile and there's quite a few other examples both small and large. That to me seems to be the so called "use-case" for m43 shooters. I actually have the Panasonic 30mm macro and use it a little, the AF I feel is better and snappier than the 60mm, but the limited working distance is a problem for the subjects I have so it only gets occasional use. I'll post some examples once it arrives, but with the advised delivery time and my schedule it'll be a few months before I get it UW.

If you are shooting blackwater I would think that the 30mm lens should be good enough provided you have the working distance as 1:1 is is only a cm or two beyond the port glass and the practical limit is around 1/2 life size for me at any rate.

On the MFO-1 I think it was not communicated very well, the image quality benefit was small and mainly seen on full frame systems and the AF benefit seems to be only on certain lens/camera combinations. Really it should be thought of as a high quality low power diopter.

For the MFO1 in my case it is really helpfull I like shooting with it.

I'm waiting some other review over the MFO2... but I'm sure I would like it too.
I'm using a rf 100 macro with the R5 and somtetime I don't dive with it because they are the chance to see some "to big creature" for it. With the MFO2 I'll probalby dive more with the 100mm then I'll be able to shoot bigger subject


The main problem for me is to make a new flip with 3 and not only 2 lenses. 🤣

This is definitely one of the perks to the MFO-3. Like the MFO-1, the 3 will only be able to focus within a limited close distance to the subject.

Exactly! Very useful tool for the right situation, but bit too much hype.

Oups it's the MFO-3...

It's possible to change the title of this topic ? ;)
