I am hopeful that the 16mm port extension (made by Saga) that I used to use for the 5T lens - will work for the 100mm and the 90mm port. But I won't know until I get a lens. Otherwise I will use the 20mm - which I have three N100 ones (one from Saga, two from Nauticam - although I am not sure these were ever actually offered for sale). Actually long term I'd like a dedicated Tamron 90mm port, which is slightly shorter than the Sony 90mm. And then I'd be able to just use a standard N100 20mm port extension for the Sony 100mm. As I don't think I will travel with the Sony 90mm once the Sony 100mm comes out. Only the Tamron 90mm. I've no idea when the lenses will ship - but when they do I will happily test what fits (although I appreciate not everyone has the 16mm port extension).

I've ordered one. No idea on wait, but it would be conveninet if it came in time for my Lembeh trip in November. Very happy that it will work with TCs - something I used to value greatly with my Nikon 105mm - for certain subjects and for adding lens options with little baggage cost for travel. This shot is a Nikon 105mm and 2x TC:

I feel that the Tamron 90mm and Sony 90mm are close to indistinguishable in real world underwater shooting. I have used the Tamron more this year than the Sony, but both are currently in my bag here in Canada, as the 90mm is such an important focal length for Sony users underwater, that I like having a back up on trips. But I also think that the Tamron is one of those measurebator favourites - yes, very marginally better, but far more noise is made about it, than real world performance gain. The Tamron is not worth upgrading to from the Sony - they are just so similar. Of course, if you are starting from scratch then its price makes it the better choice (but do be aware that being slightly shorter it does cut off 'vignette' slightly on some ports/wet lens combos specifically designed for the Sony 90mm). However, if a 100mm is coming soon - I would not encourage anyone to buy a Sony-fit macro lens right now until they see what appears and at what price.

Another rumour with the same details... https://www.sonyalpharumors.com/is-the-sony-100mm-f-2-8-gm-macro-coming-on-september-30/ And rumoured release coming soon.

Amazing colour on that mossy. Lovely!

Yes, way more powerful. Most of the strobes I mentioned above are more powerful than the Subtronic Alpha Pro (which was impressive in its time), but a step (or stop) or two below what we have now.

I have always taken light very seriously in my photography and been willing to invest in the best strobes around, even when finances have been tight (as they often are working as a photographer). I credit using quality strobes (and me paying attention to using them well) as being a major factor in me developing a successful career as an underwater photographer. I jokingly credit Sea & Sea for my success - and their marketing machine that kept many of my competitors shooting with inferior light to me for more than a decade! The Subtronic Alpha Pro strobes were very good in their time (I also had Subtronic Alphas, Megas and Gammas - but preferred the light from the Alpha Pros). They had a pleasing quality of light, good colour temperature. I used them as my main blue water wide angle strobes from about 2000 to 2012. They were not especially reliable, and Subtronic service at that time left a lot to be desired. I used INON Z240s as macro and green water strobes during much of this period and onwards. When I could afford new strobes i chose Seacam 150s - which I got in 2012 and used these as my main strobes until 2019. These were noticeably more powerful that the Subtronics. The light was not as soft and i usually used the Seacams with diffusers on them and positioned them slightly further back from my subjects than the Subtronics. But the light is very good, colour excellent and the light went further. The Seacams were more reliable than the Subtronics, but still needed regular servicing. The battery packs and cables were their weak points. Many of my friends shot Sea & Sea YS250s at this time - but I felt that the Seacam was about a stop more powerful and had a better quality of light too. I was very happy there were so many people championing other strobes. Through much of this time I used the Inon Z240 as my main macro and green water strobes, upgrading to the original Retra flash for this purpose in 2017, I think. I went for the original Retra flash because it had better wide angle ability too, while still in a small package. I did a couple of trips with the Z330s, but these were too wide angle focused. As the Seacam 150s aged I tried the ONE UW and Seacam 160s as replacements, but settled on the Retra Pros. All there have great powerful light - but the Retra Pros did so in a smaller package and they had the most pleasing soft light in my opinion. They were also cheaper! I stayed with Pros and skipped with Pro X. I then moved to the Pro Max - the light is basically the same as the Pros, but the battery performance is way, way better. I’ve tried various Chinese circular flash tube, lithium powered strobes - Kraken 160, Supe D-Lamp and these are all fine. The light quality is good. Colour temp a bit cool. The power a step below - I think they don’t get enough light out of the tube despite plenty of power behind it. The Backscatter HF-1 is the most powerful strobe on the market currently (thatI have tried). It is fun to have so much power and I have used them in preference over the Pro Max on big animal trips like with sharks. But otherwise they tend to be used as backups or as off-camera strobes. They are powerful and reliable and I think the light is decent, but not exceptional. The light is best with the warmest flat diffusers. The Retra Maxi is slightly more powerful, but is not on sale yet. I’ve not shot the Ikelite 230 in the ocean, only in the pool, but these were a whole stop less bright than the Maxi (and therefore almost the HF-1). Also I did not try the Maxi with the final reflector set up - but as I tried it, it was very similar to HF-1. Retra say the production version will have improved quality of light. I will probably replace my HF-1s with a pair of Maxis when they are available. The brand new Retra Pro Max II pretty much matches the HF-1 in real world power, with a much better quality of light and in a smaller package. I used them on every dive on my last trip and plan to use them as my main strobes going forward. The Marelux Apollo 3 is impressive as a companies first strobe. But they are less powerful and have a poorer quality of light to the HF-1, but they are probably more powerful than my old Seacam 150s - so right up there. The light is too directional and lacks red, giving poorer colours when shooting them on the reef. The high speed shooting mode annoys me. In standard mode you can only shoot slowly, and then in the high speed mode you can’t shoot at high enough power - because achieving 10 frames a second is prioritised (a mode that did 5 frames a second at a high power would be great - but you can’t have that). It is like making a car that can do 50 kph and 200kph, but nothing in between. I also think that the Lumilink system has very limited practical use - so bulking up the strobe and bumping up its price to have this is a pity. And sadly it is also impossible to get a honest opinion on any Marelux product because the internet is filled with paid opinions. As you asked for my subjective opinion - I’d stress that this is all my subjective opinion. We’re lucky now that we have a load of strobes that are way, way better than Z240s and D1s that everyone was using 10-15 years ago. I’ve said/joked several times that the popularity of Retra strobes amongst serious shooters frustrates me - because everyone has great light now - and something that used to differentiate my work has gone.

The failing is not the entrants or winners, but I fear that Compact Contest Categories are not really achieving the purpose they set out to. Compacts are increasingly niche and that niche has also become incredibly wide.

This is a real challenge for Compact Categories in contests. Compact Categories were started to enable those with lesser cameras to show what could be achieved without spending the big bucks. In recent years some Compact Category winners have been rightly criticised for using super expensive lenses, that take the system cost way above that of most SLRs or FF mirrorless. Now we have a compact that costs more than most of those cameras too...

Here are some thoughts and pictures from shooting them in the Red Sea

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) https://www.nauticam.com/collections/water-contact-optics-for-nav/products/mid-range-focus-optimizer-3-mfo-3 My flip adapter is a standard double Nauticam one.

Thoughts and images from MFO-3

Let's see a picture? I've not seen the final product yet. Matt and I have a UWPS episode coming on Saturday on the flashes. I took almost 10,000 shots with pre-prod units in the Red Sea last month. Alex

I have the Carl Zeiss designed Ivanoff, which I used extensively with a 20mm lens on Nikon SLR (my friend Peter Ladell converted the port fitting). I have not converted it for my Sony because the Nikonos 15mm has almost identical performance, but I am sure I will experiment with it again in the future. I used it to take quite a lot of photos, such as this well-known one: Wildlife Photographer of the YearRig diver | Wildlife Photographer of the Year | Natural...Diving beneath the oil rig, Alex had to anticipate when the cormorants would burst through the fish shoal. The birds hide behind the legs of the rig after they plunge into the dark waters, gaining...This is another: The Zeiss corrector has two lenses - the port and then a second corrector lens that goes on the front of the camera lens. I tested it with and without this internal corrector lens - and without it the Ivanoff was no better than a dome, but with it, it rivalled a water corrected lens like the Nikonos. At the time I tested one other Medium format Ivanoff corrector port (from a Mamiya 6x7 housing) and this was similarly "no better than a dome" - and it did not have an internal corrective lens. Lots of Ivanoff style ports were made for video cameras in the 90s. They weren't amazing optically, but worked well enough for the low-res video of the day. They were smaller and more robust than domes and I feel worked well with the physically small lenses on video cameras. A frustration with the Zeiss system was that the internal corrective lens was quite small in diameter (made for the Hasselblad SWC) and this limited the lenses I could use with the port to those that had a physically small front element. I tried a number of lenses, but none worked as well as a Nikon 20mm. I would put more effort into reviving my port - but for now the Nikonos 15mm is basically doing the same job for me. Yes, I don't have AF, but that is less of an issue than you might think. And it is smaller and lighter than the Ivanoff. I'll watch your tests with interest. Because I quite quickly lucked into a system that worked really well, I felt I never tasted variables that thoroughly. Once I had the right port extension and found that the internal lenses worked great with the 20mm, I just got out there and used it. When ever I varied things the results deteriorated quickly, which also put me off doing more tests. Alex

My experience of the rumor [sic] sites down the years is that they rarely have any insight. In general they speculate for clicks, rather than having any proper info. I have seen them wildly wrong in their predictions of items I have already shot. However, I am inclined to believe this one. I think an ultimate-quality macro from Sony is overdue. I had hoped they may also choose a focal length that would differentiate it from their existing offerings (100 vs 90 is not really different) - but I also see how 100mm is probably the sensible choice for them when competing with Canon and Nikon.
