Till now I have plus $ 500 for the next trip 😊

As the bars on the side extend to the dorsal fin I would go for the Barfin blenny Malacoctenus versicolor.

Well it works fine for a u4/3 at 60 mm, close enough to 90 on APS-C. Not sure that it really extends the focus range though. You will need more flotation, on a flip adapter it is quite heavy. The spine cheek was shot with the Panasonic 45 on an OM-1 with the MFO

Hi Bill, it works ok, but can you expand on the advantage? Did you experience a better corner sharpness and/or a snappier AF? I always liked the behaviour of my Pan 45 so I would like more info before I draw my wallet.

Wow, great film. Finally thankfull to my french teacher.

I Just did around 30 dives in Lembeh and had the MFO for most of it, I think it's very easy good ot leave on for general macro shooting. You kind of don't notice it's on until you nee dit and it just allows you to get a tiny bit closer than normal. With regard to focusing quicker, I didn't notice that but I am pretty used to shooting macro and generally start off with the camera in pretty much the right place to make focusing instant. The image quality from it and it doesn't have any colour casts like some other macro lens such as the EMWL 

 

Hi Byron, did you notice a change in DOF using the MFO?  You separated the pigmy seahorse by panning, it made me wonder whether the MFO make it harder to get separation by DOF. Specialy relevant for small sensors.

Would be great to hear about experiences with a MFT camera. For instance with the Olympus 60mm macro (quite a hunter) and the Nauticam 45mm macro. 

Finally received the 'Barmaglot alieexpress adapter'. I was a bit affraid the combination wouldn't fit in my Olympus M 5 III but it does. The trick was to connect the cables first before sliding the camera in. It helps that the adapter is extremely flexibel. So flexibel, that I am happy that I also ordered a spare.

Anyhow, the weakest point of my small camera, the battery, does not bother me any more.

My Olympus M 5 III with a Nauticam trigger has no problem at 1/400. The narrow band on top appears at 1/500 Underneath it you still have more than a 3:2 image like in many other cameras. 🙂

I always like to look at photos or videos of less known coasts. Beatifull scenes, great footage! And nice to sea that the sea lions thrive so well.

How much space do you have in the case for the connector? I can look for my documents if you like. My solution also worked in an RX100 case where there was hardly any space.

Its not the plug but the length of the conector cable that I have bothers me. With a lot of effort it will fit. Not nice by itself, but I am  afraid that one day it will "put its foot between the door". The aliexpess one might sove this.

Great messages Timo and Barmalot!

The possible option at Dive and See that Chriss mentioned does not work.  I connected them and found out that their bulkhead with Micro-USB  is made to connect to a device above water. And a bulkhead like the Nauticam one, also USB-C at both sides.

On Amazon I only found larger adapters. I stripped one to dimish it's size, and gave up. Especially in the Olympus M5 ii there is little room. I'll try the aliexpress adapters now.

Thanks for the information, I'll think about the Dive and Sea one, double price...

And yes, the EM5 III will charge once it is switched of.

Sounds great, I am jealous.

My Olympus M5 III has a micro USB connector so I considered to buy the bulkhead and add a USB-C to mini USB connector. But I gave up, likely it will to take to much space with the chance that the cable will get squezed when closing the back cover. Brr, an extra chace of leakage. 

Nauticam, please make a mini USB bulkhead.

Then, there's advanced DIY from my friend Rosario Scariati for his WACP.

With this solution you don't need to remove the cap underwater but you just open it...

 

 

But now his housing is unreachable (?)

Or a DIY solution 

Like this one with a neoprene front.

That’d be the Retra then, makar0n? 😝

 .. reasonably priced as well.

It would be great if we could make a list of judgement systems of the major competitions. So every one can judge for themselve if  he/she want to take part. Is there enough knowledge here to make such a list?

There's a great difference how well your pictures are judged in competitions. See how frustrated Alex is about many of them.

I read this discussion for some time and started to wonder about the role treshold values of the camerasensor.

@Chris Ross and @Architeuthis are is right when they argue that "Changing the shutter speed doesn't change the the ratio of red/green/blue photons, just the total number of photons that arrive."  True, but after arriving there must be enough photons to surpass the treshold value of sensor elements of the camera. As the ratio of red light is the lowest,  underexposing  may cause a too low amount of red photons to activate the 'red light sensor elements'.  Not all in 'red sensor elements'' but relatively..

I am not an expert, but it sounds convincing to me 🙂

The link broke, there is anothers picture on FB. Also from the front, but now you can see a battery compartment that looks the same as the previous version. Obviously they are trying to create a hype by showing it step by step. Rather irritating :-{

This prototype is depicted at last but I could find no further info. Looks nice and still small with the flastubes in T position like the earlier versions.

From my point of view in case of massive backscatter it doesn't help and just makes a bad photo less bad. However, in the case of a minor backscatter, it's totally awesome. So I definitely recommend it.

Yes massive backscatter shots do not  turn into perfect photos but it can change the image from 'aghh, throw away' to 'ok, I'll keep it'. (Left -> Right  on this shot). After BSXT I had to manualy take away  more points but without the plugin I would not even have tried.

I wonder why I still had had this shot, probably because it was my only one from a red 'blue jellyfish'. And now I have to confess that, where I said before the plugin is to expensive, I bought it. And it worked, I even might be a bit less frustrated when I see all those floating particles in our waters again.

For M43 shooters.  I designed a zoom gear for my Panasonic Lumix 14-42mm lens in a Nauticam housing. A nice lens with the WWL-1. At first it was a bit narrow to put on the lens but not problematic. I use it for two years now, it works really fine.

I have printed out the snoot for Inon Z330 (small version) according to this file here and it works perfect: https://www.thingiverse.com/thing:4753831

 

This file and numerous other files for UW-photography can be found on this Webside here, type in e.g. "Z330" or "Zoom gear", but I cannot confirm that everything works (I printed just the snoot):  https://www.stlfinder.com/

Hi Wolfgang,

Does the snoot screw firmly on your strobe?  I have bought custom made beam restrictors for my Inon Z330 strobes, but they are a bit short. To design new ones I could use the lower part of the snoot design.

My latest liveaboard forbade even mobiles to be loaded in the rooms. I never dived into the issue but they were very strict on it.
