Thank you, yes AF area point presets do help a lot with focusing in low viz with the OM1 I find.

I've been using the EMWL since its release in 2020 mainly with the relay. On the GH5s, I made a small tray at the back of the housing with a bayonet holder to store the full system assembled to enter/exit water. On the Z8, that system was impossible to set. I go to the water with the EMWL fully attached on my on the BCD D-rings. I have printed caps on both ends to protect the lenses Depending on your setup, an alternative solution - especially if you don't use the relay - is to enter/exit the water with focus unit installed and other lens tips stored on the EMWL arm bayonet holder or in small mesh individual mesh bags. In all cases, you have to install/clean all EMWL components underwater. While I haven't used it, I think the EMWL flip system is too complex to be practical in the field (and I must admit, I've never seen anyone using it on trips).

I don't doubt your images in anyway and I have no idea if the MWL-1 is optically similar. The link includes some sample images but unfortunately they are locked away behind a password. The f13 image seems visibly less sharp in the corners, though it's hard to tell at that scale. I seem to recall looking at the linked samples images years ago, but can't access them now.

I recently got the Turtle3 manual trigger for my Z8 Nauticam system. Didn't need or want TTL but I did want to try HSS and Rear Curtain Sync. It's only about $350 or so. It seems to work well so far.

Just deleted the duplicate post for you.

My standard preset for UW is using AF-C, I haven't used AF_C plus tracking. In tropical waters I've found the AF is pretty good. Recently I was shooting grey nurse sharks early in the day in lower vis waters and it didn't want to focus on the shark body until I got my small single point on an edge, like the outline of the shark, I'm thinking for subjects like that I'll try using a centre cross array of AF points. Normally if there is contrast in the subject it focuses pretty quickly.

Since you are looking at the 26601, i assume you want TTL and the works instead of the manual 26350. I have Turtle for Sony and and im happy with it. Theres plenty of UW-Technics user on the board also, and im sure you cant go wrong with them either.

If the Kraken is in any way similar, that's an exaggeration at best. I often shoot it at f8 and up. The shark photos above were all F8 and they are very sharp.

the MWL-1 sounds great but was never particularly popular, A prime reason seems to be the recommended aperture of f16. I only ever found one review of it which confirmed f16 was required to be at its best and that you could use at f14 at a stretch. Here's a link to the review: Wetpixel.comReview: Nauticam MWL-1 Conversion Lens by Jack Connick ::Wetpixel is the premiere community website dedicated to underwater photography and videography

Friends: Last year, while diving Derawan in Indonesian Borneo, every other image was unlit. Originally, I thought the problem might be improper sync settings in my Nikon Z8. But I verified they were correct. The culprit seems to be my flash trigger. I've been using Retra Pro Max strobes with a Nauticam NA-26308 TTL trigger, which was originally developed for DSLR cameras. It's possible that new firmware updates in my Nikon Z8 have rendered it incompatible with the old flash trigger. Nauticam now makes a newer flash trigger designed specifically for Nikon mirrorless cameras (NA-26601), which costs $760. UW-Technics and Turtle also make flash triggers for the Nikon Z8, priced at $569 and $440, respectively. Does anyone have experience with these newer flash triggers? I'd love your recommendation for which to install in my Nauticam NA-Z8 housing. Many thanks!

Thanks - not on the A7SIII as far as I can see. I ran some tests yesterday, taking a static clip of colourful sujects, same lighting, exposure. Graded results are very similar for non log profiles, but I would say most promising were either no picture profile (darker image to begin with, which might be linked to how ISO are handled?), and Cine2. All and all, I could get very similar results in all profiles, but HLG / SLOG3 required the most extreme exposure and saturation corrections, and the conversion to 709 is problematic on my software. Hard to tell Look at the scopes narrows it down to: - PP off (great) - Cine 2 (flatter, more latitude for grading) HLG3 is also very promising, being a hybrid log without the ISO or ETTR exposure constraints of S-LOG3, but not compatible with my current NLE. The conversion to an 709 colorspace just doesn't work on my version of FCPX Worth coming back to when I get a new computer and can run more recent, up to date software. Ungraded picture profile off: Ungraded Cine 2: Ungraded, uncoverted HLG3: Ungraded, unconverted SLOG-3

BTW, one of my regular dive buddies has been borrowing my Kraken for the last several muck dives we have done off the beach in West Seattle. He is really having fun with CFWA shots of giant nudibranchs and loves shooting the Kraken.

Part number 31706 Marelux to Nauticam N120 extension ring 20, retail $200.00. Not yet posted on the products page. Any one going to take a shot at why Canon RF 28-70mm F/2.8 is not supported?

Here is a set of 4 photos taken with the Kraken 09s and Nikon 60mm., all on the same dive. The first three are of an 8 foot long Sixgill shark taken from just a few inches away. The fourth is a 1cm hermit crab taken with the 60mm and MFO-1. The Kraken (and I presume the MWL) is very versatile. Excellent for CFWA, and then you have the option for true macro with the 60mm. I tend to use it on dives where they might be a chance for bigger subjects, but also good macro opportunities. The Sixgill dives are ideal for it. You spend about 30 minutes (hoping to see a shark) at 90-100 feet until you exhaust NDL then you head up to shallow water with great macro subjects. Aside from that I like to use it for CFWA scenes and not standard wide angle subjects. Corners are not awesome, but that is not always relevant as you can see below.

You might experiment around with CineEL — which I believe was added in a firmware update.

Hi @Alex_Mustard and @MatthewSullivan , I remember seeing a post somewhere where you were asking for ideas for future episode topics for the Underwater Photography Show ( #UWPS ) on YouTube. I can't remember where it was, but it reminded me of something I'd genuinely love to see discussed on the show. I recently watched your "Nauticam Optics Primer" episode, which I really enjoyed. It covers a great range of Nauticam optics, and of course the EMWL earned its own dedicated episode. However, it left me wondering: was there a particular reason why the Nauticam MWL-1 wasn't mentioned at all? Was it and I just cannot remember? I've always found the concept behind such a lens fascinating, converting back from macro to true wide angle on a dive. There is also a review by Matthew, about its main (or so far only) competitor, the Kraken KRL-09S: Testing the Kraken KRL-09S Macro Wide-Angle Conversion Lens which makes him highly qualified to show some test images and discuss the pros and cons of such a lens. It would be really interesting to hear both of your opinions on this whole category of optics. The MWL-1 never really seemed to gain widespread adoption, and I've often wondered why. Was it image quality? Sharpness? Handling? Cost? Or was the concept itself simply too niche? I know if was mainly developed for the Nikon AF-S 60mm, but seem also to work on some Canon and Sony Macro 90-100mm lenses with less AOV as a result. I'd especially be interested to hear how you think the MWL-1 compares today with more recent water-contact optics such as the Nauticam MFO-1, MFO-3, and now the Marelux MacroView MV-60. These products seem to point towards an interesting philosophy: instead of owning separate dedicated wide-angle and macro systems, perhaps photographers could build a very flexible setup around a single 90–100 mm macro lens (Canon, Sony, Nikon, etc.) and then simply swap between one or two wet optics during a dive depending on the subjects they encounter. Do you think this concept has a future, or do the compromises still outweigh the advantages? Has this category quietly evolved, or was it ultimately a technological dead end? I'd love to hear your thoughts in a future episode. AND MOST IMPORTANT: see some you your excellent sample images discussed in such an episode! Furthermore everybody is invited to discuss experience and photos with these lenses in this thread on waterpixels.

With GP13 i was filming much closer to the subject due focus distance, on the Mission 1 pro in certain conditions it might work, but theres always the temptation to get closer and closer to the subject.

F11 is the bare minimum. F13 and F16 are necessary sometimes and who cares about diffraction 😀 On these macro shots a tripod is mandatory. What NLE are you using? On Davinci Resolve, the Midtone details tool makes miracles. It's a micro-contrast tool that sharpens or softens areas with high edge definition. Ciao

Hi @Chris Ross , I have version 1 of the EF to m43 Metabones adapter and I am having issues with AF-C to the point I can only use it with AF-S which is not great for moving subjects and forces me to recompose all the time or get the odd blurry shot every now and then. I am running the latest firmware on the adapter and the camera (OM-1). I was wondering if version II which claims to have full PDAF compatibility has this issue. Have you used the 8-15 with AF-C or AF-C + tracking? Cheers

@Alex_Mustard has published an excellent review of his OPP test drive in Raja Ampat on his homepage, which can be found here: https://www.amustard.com/seacam_opp/ What I especially liked and found very helpful to sort all the optical choices is the AOV graph he provided as a slide in this review. It especially emphasizes the range of the FCP that jumps right into your face when viewing the graph. I personally wondered how the popular Canon EF 8-15mm fisheye with teleconverter solutions would fit into that scale and created this refined graph:
