Is anyone else having trouble getting some of the bar graphs in the article to display? For me some of them just don't display as I scroll down and leave a large white space, and I get a blank white page when I click on the "Full Screen" buttons. If anyone is able to turn the article into a pdf and send it to me I would be grateful!

Lens is sold now... Macroport 105 N120 still available (220 Euro inkl. shipping within EU)...

What an outstanding encounter! Thank you for sharing it - I'd still be buzzing!!

RIP, dear friend.

down here in Japan as well... Error code: PR_END_OF_FILE_ERROR

Just clicked on Wetpixel for the first time in weeks and it does not seem to be responding. Anyone else able to bring it up?

HiKenjiang, Welcome aboard! We hope you'll like the community. Ciao

Price quoted at $999, so more than the MV60 which makes sense given how much more glass is in there. I'll be very curious to see test shots and specs.

Update: Looks like Matt Sullivan was able to get this lens behind the WACP. Have a read below. https://www.nauticam.com/blogs/news/hands-on-with-the-nauticam-wacp-1-and-nikon-z-24-70mm-f-2-8-s-ii

I am from Taiwan and have 15 years of diving experience. I enjoy underwater photography and currently use an LX100+nauticam housing as my underwater photography equipment.

Thank you very much!

So I guess that means no filter threads as well. Looks like we both guessed wrong.

As I look more at the photo from the nauticam website that I posted, I think I see now that the objective lens is right at the front of the lens, and what I thought was a recessed lens is just due to the limited reflection off the front glass. Sorry for my error.

Good points, surely a lot of things to consider. A pitty that the review ends with an advetisement, which undermines the feeling that the text was written from an objective perspective. The best thing that could happen is that the tecnicians of both companies would sit together to make a improved version.

The MFO-3 and MFO-3II are optically identical. The glass supplier changed so the nomenclature changed to differentiate for any repair/glass replacement purposes in the future. The dimensions are a few MM different but that is it

Hi Karlo, I love the diving in Croatia, very different from Red Sea type diving.

The test was dome with an older generation Apollo III and Marelux is improving with each new generation. Guide number is a balance between brightness, bean angle, fast recycle and more. I suggest you read the Retra response to the Backscatter strobe test.s in the thread above. In the case of the MX V BS top strobes the MX has a beaded dome with a 120 degree beam angle V. flat front with around 100. beam angle. The MX beaded dome softens the light output while the BS strobe needs a flat diffuser with a loss of a full stop of light to get to 120 degrees . Go to Marelux.co and checkout the difference shooting at 5 and 10 frames a second and decide which is more powerful and efficient.

Backscatter (BS) recently published a comparison of more than thirty underwater strobes. It is an impressive amount of work and contains genuinely useful data. We have now gone through that data in detail, repeated several measurements ourselves, and published our findings here: https://www.retra-uwt.com/blogs/news/a-closer-look-at-backscatters-strobe-test-retra-uwt We found several issues that we think deserve discussion: Guide numbers are plotted on a linear scale, which makes differences between powerful strobes appear larger than they are in photographic terms. We replotted the data in F-stops. The beam viewer uses different exposure settings for some strobes and does not normalize their centre brightness, so it should not be treated as a calibrated beam comparison. There are almost no error bars, variance figures or trial counts, making it difficult to tell whether smaller differences are meaningful. We could not reproduce the reported Retra Maxi color-temperature behaviour or its reported Boost recycle time. The Isotta RED64 guide-number result appears inconsistent with BS’s own beam images and flash-duration data. There is also a commercial context worth acknowledging. BS is both a retailer comparing products it sells and the owner of a strobe brand included in the comparison. That does not automatically make the data invalid, but it does make transparency about methods, uncertainty and commercial interests particularly important. This commercial focus is also visible in the content BS produces for its website and social media. The commanding majority of its promotional effort is focused on its own branded products. Including many competing brands in the test is commercially useful for BS. It creates the impression that they have a complete overview of the market and can offer neutral advice on almost every available strobe. Many customers come to BS precisely because they are undecided and want guidance. Once BS is accepted as the authority with all the data, it becomes much easier for them to steer those customers towards their own products. This does not automatically mean that the data is false, but it is an important reason to examine how the testing and presentation may support that sales strategy. The same standard applies to us. Retra manufactures two of the strobes discussed in the test, so we are not a neutral third party either. We have disclosed that interest and included our methods, measurements and reasoning so they can be challenged directly. Our intention is not to dismiss BS’s work. We would like to see the questionable readings checked, the charts improved and more information about measurement uncertainty published. If anyone finds an error in our analysis, please point it out. We will correct it. I’m interested to hear how others interpret the data, particularly the color-temperature results, the RED64 reading and whether guide-number charts should be presented in F-stops.

@Phil Rudin - the recent Backscatter strobe tests reported that the Apollo III 2.0's output was significantly less when tested compared to the Marilux claim of GN44 - has Marilux made any comment about this?
