... or it is perhaps confirmation that extra 10mm in space between port glass and the lens won't matter (1.4x is 17.4mm while 2x is 27.2mm added length to the lens). Which means that using old port 105 with 30mm port extension might be feasible for new 100mm macro (?)

Awesome! I would be terrific - if you had time - if you could show us the differences on screen. It could be a room scene with window and something behind it (garden, tree, anything) and shot by iPhone in HDR (default) and posted to YouTube so it would show HDR mark after posted. So it would be HDR video. It could also help you to determine best practice while underwater. With my Shinobi I found PQ mapping having the most dynamic range but HLG mapping keeping screen brighter. On my Sony A1 that is. I will try to do something like that later to show example.

This is amazing! What size of battery can you fit in that housing? And Feelworld model?

Does this have HDR mapping in the menu? Which options and do they work? Thanks!

Yes! This is what I mean! What other options it shows under that HDR option beside 709 please?

Very nice! My goal was to place monitor a little away from me - also to access topside buttons easy - and being able to tilt but the fixed bracket has its own advantages. Does this Kraken has HDR PQ or HLG mapping of Slog3 signal available? What I don't like on Shinobi is inability to access settings underwater and what I do like is battery lasting for 6 dives at 1000nits and the HDR screen with that PQ option.

Sail! That! Exactly!🤣 If I may share my way dealing with overexposure... even though A1 has different sensor, also dual gain but maybe different... anyhow - I learned that ISO on A1 doesn't matter. Heck I can go 30000 and as long as I properly (over)expose I see no meaningful effect on noise. So I started to use ISO as gain and with shutter and aperture locked in I mapped (typically shutter) wheel to ISO. I display waveform on my monitor and push it to upper third as high as not to get cutoffs. Sometimes the overexposure is actually 3+ (!). On Nauticam housing that wheel is greatly available for thumb operation which helps me adjust 'gain' on the fly - like when following shark from deep blue to surface background. Not sure how this is going to work for A7S3 sensor but for both A7S3 and A1 all YouTubers were swearing by using base ISO - only for me to find out that it was utter bollock. At least for A1. And of course this wouldn't be possible without external monitor (with HDR conversion switched on). So cheers to sailors 😅

nicely done! we were on Calipso last September and it also was a blast. 3 whale sharks over at Darwin - or one three times on three dives 🤣 Out of curiosity - I see a lot of noise on your footage - especially in the blues. Were you overexposing at all? On my A1 I have to brutally overexpose log footage otherwise I get a lot of noise too. Glad to see somebody else is lugging monitor around too :-) mine is shinobi :-)

I assume you did MENU → (Setup) → [Power Setting Option] → [Auto Power OFF Temp.] and select [High] Not to worry, no damage possible Even then the camera produces a lot of heat at 4k100 and so trapped in housing in warm waters - like 28C+ - will cause it overheat. Yes, using external monitor helps but there is tradeoff in terms of size and travel weight. Still totally worth to me.

I would disagree on a problem - current N100 90mm port doesn't fit the lens with cap so it sits pretty tight. I am estimating worst case scenario with 30mm extension is the gap of like 20mm between the front element and the port glass so it shouldn't even vignette and certainly it won't be able to focus on front glass. The EMWL implications are unclear to me - if any, I just can't picture what kind of woodoo the focus unit does. Canon 100mmRF lists both #2 and #3 for its FOV but what kind of effect the extra 20mm between the lens and the focus unit will have I just can't picture 🤷

Nice! I'd like to think that 30mm N100 extension which I use for WACP-C will work also with existing N100 macro port! New lens is 19mm longer than the old one. And for TC when TC if TC just another extension. Keeping travel light! 😁 The questions is how EMWL will work with this?🤷

They certainly have better taste I choosing monitors for which to make housing. What on earth both Nauticam and Marelux were thinking when making housing for touch only monitors from Atomos ... 🤦(save for recorder)

Yep, from the marine life composition through corrals - we did dive the same location! 😄 Nice pictures!

Excellent pictures Luko, you've captured the essence of Halmahera! We were passing on liveaboard mid July this year and can confirm everything and above from your report as for that place. The only thing I'd add are the humphead parrotfishes, this one from Pokal island next to Sali Bay. Other than that you were spot on with diving and weather conditions. Mostly grey above water and vis so so there. But no wonder - you were staying in middle of river! Imagine the sheer volume of water passing through the strait with unpredictable tide schedule combined with the effect of islands blocking that straight and you easily change your opinion on guides not letting you go when they deemed currents too strong :-) It's not as much about the divers skills but rather about the unpredictability and sheer strength of these currents. On one dive in there a current hit us so strong it almost ripped my A1 rig out of my hands. I bet your R7 setup is not smaller :-) Can't really take pictures in that :-) On another dive our group was split in half with one part making a circle finishing where we started - all the while in big current - and the other half ended a quarter mile down the road... Funny for us but not so much for the dive operations :-) For me Halmahera trip (we started Lembeh, moved across and also explored islands near Halmahera, was terrific. The corrals were so rich I found myself taking one picture after another just to look at the previews on my monitor! I honestly think the best way to enjoy Halmahera for non-photographers is to have like 15K lumen floodlight and enjoy the colours this way :-) True, shoal fish can be seen only at middle of the Molucca sea at Gureda island - Pula Tifore but we've also encountered sardines at that Pokal place I think the hype - if there is any - is that it is so remote and so new for many people. And also perhaps fun in some currents situation. And I think it is well deserved due to combination of colours and variability of marine life - I will skip my macro life pictures as I do not want to hijack this excellent report thread :-)

Interesting question indeed. 2nd gen AKA pro version of I360 housing has larger dome right? So the problem might be in the distance of virtual image perhaps? Perhaps it is unsolvable until someone creates diopter corrected lens either for camera or housing which could play with camera and virtual image better... questions no answers...
