Mainland China / Shenzhen, if I'm not mistaken?

As a side note, stabilisation is very much an issue for video - I think this applies to both Marelux and Nauticam conversion lenses. From what I understood, the change in focal length confuses lens stabilisation calculations and the image bounces all over the place. I use the MFO3 with the Sony 100mm macro on the A7SIII, and turned off lens OSS (but didn't have to change anything with IBIS), no issues. I've heard similar feedback from someone shooting video on the Nikon Z8. But it's very much a video related issue. I think Davide had noticed a similar issue with another lens conversion for video - seems like the changes in focal length and real time lens stabilisation leads to issues. Manually setting the focal length in camera might be a work around if your camera allows it.

The only issue with lens stabilisation would be the fact that it is a ~35mm lens instead of a 60mm lens at least for the MFO3. The MV60 should be a similar multiplier as it is made for the same job so it should perform the same way a far as stabilisation goes. It is a camera thing rather than anything to do with the MFO3/MV60. I haven't tested video which may have different problems, but you can manually change the focal length in the menus of the OM-1.

If that is in fact an actual picture of the front of the “new” MFO-3 II, it does not look any different than the original MFO-3. However, if Nauticam were to change something on the II version, I would think they would add a threaded portion to the front like the MV-60 instead of that push on M82 FILTER HOLDER they offer for the MFO-3 instead of that redicules . that Phil mentioned is doubles as a protective guard for the front of the MFO-3. While it is treaded for 82mm size filter, they are not cheap (listed at $57 USD) and made of anodized aluminum that will instantly show where it made contact with a rock, coral, or anything else that is really hard that it is bumped into.

I have not heard of any IBIS issues using the MV60 and yes it should work well with the Oly 60 macro. Marelux US has one left in stock and more arriving soon.

The MFO-3 has a bulbous/curved front glass which was not designed for adding filters like ND's .They have an optional push on filter holder for an additional $50.00 plus for version I. I suspect this may now be built into the lens on V II. This is one of several differences for the Marelux MV60 which already has flatter front glass and a common 77mm thread size for a verity of filter types.including yellow for Flora.

A video well worth watching if you are considering the A7R VI. The best Youtube video explaining the value of the upgrades V older models for underwater use as both a stills and video camera,

Aloha and welcome @Karlo !

I could be mistaken, but it appears to me the MFO-3ii now has some sort of built-in lens shade/protector

(have been using EMWL regularly for 2 years) we considered the reverse viewfinder. upside is more compact setup. downsides are dedicated rig essentially (you will have to switch the viewfinder when switching lenses). and you cannot go regular macro to emwl underwater which is one nice feature to have on some dives. we did use a monitor for a while - that enables you to flip the image back and forth - while still having a relatively compact rig (you do have the monitor on top). at then end we ended up diving only the 'classic' emwl setup with relay lens and angled view finder.

Hi Karlo, Welcome aboard! Video or photo? 😈

have been using the think tank mind shift first light for many years - looks casual (doesn't scream "photo gear inside") and has a lot of space - especially a nice depth to it. travelled to many continents - has passed in pretty much all places for carry on. there are two options - 35l which will definitely go pretty much anywhere - and 45l which is more of a US airline version. it's been sturdy and protective while relatively light.

we do a lot of shore diving with the EMWL - attach the focus unit on the housing (with no cover - the glass is recessed and pretty well protected) - and have the relay with the lens attached in my pocket. once we are in a safe spot we assemble it and flush all connections (there are tiny bubbles in there as well as sand in our case).

I’m seeing good things about the Marelux MV60. One concerning thing I saw was that it doesn’t play nicely with lens image stabilization. I’d hate to have to turn off IS on the OM as it works so well. I’ve tried the MFO-3 with my 60 mm macro lens and loved it. Unfortunately they don’t seem to be available. What can I expect with the MV60 on my Olympus 60mm? Is it available?

hi I am new member from Croatia. glad to be here

Thanks for the detailed feedback from a real use case. Two questions: Did you find any differences or did you have to change anything in your setup since this monitor is supposed to be much heavier than the previous one? Others and I are using the Weefine 5 inch with great satisfaction, but we drew a wild card with the extra features. The Zebras are not real zebras. In short, the firmware feels homemade. How do you like yours?

Many thanks to everyone for your feedback. I still use the ports and domes with an Isotta housing with D500. And as mentioned, I have the viewfinder for sale, and I’ll be putting the electrical cables up for sale shortly. To be honest, I was thinking of a much lower price—around €200 for the housing and the two D300 bodies, lol, 😅 I’m raising funds for my next piece of underwater gear = GAS 😃
