#355266 FlexiTray Trigger - Need someone who has a NA-BMPCC!

Posted by thetrickster on 10 December 2014 - 12:37 PM

I think with anything Nauticam related, its always well/over engineered!


I get a feeling mine will be a lot simpler!


The basic mechanics of it will be (I'm guessing!) is that the trigger is hinged at the very front (or the arch of movement is the greatest), at the back of this will be a flat area, which as you pull the trigger will go UP and engage a flat area on back part (with the bar to the housing trigger). As this back part is hinged in the middle, it will cause the rear of the back part to go DOWN.


Getting the angles / force right, I think is were the Nauticam engineers are craftsmen, and I'm not...


I think I've worked it out... sort of...I was wrong above....


the rear hinge for the downward part, isn't the rear pivot at all (on my drawing) - its the bottom screw on the back of the unit. (2nd photo from DiveMasterDewey) that is, its a L shape movement. That is why there is a cut away from the side of the trigger, you pull it, and the right hand side back goes up, which then pushes on the opposite pivot causing a 90degree transfer...causing the back bar to swing on the bottom nut/axis to the left.

Hi All,


Because I'm tight and not made of money, so not going to buy the NA-GH4 for the time being for just for the trigger, I'm looking at fudging together a grip Trigger for my NA-GH3 on a FlexiTray similar to the one on the BMPCC.


I've looked at others, but the NA-BMPCC trigger is the best one to base my idea on I think!  I've looked at the photos on ReefPhoto and I can guess at the mechanics of it.


But if anyone has a housing and would be willing to take some photos of it and describe how it works, that would be sweet, as it appears to have the trigger on one pivot and then another to press down on the housing button.


Thanks :)



#355083 Anyone used a 'Deeproof Housing Carrier' with a FlexiTray?

Posted by thetrickster on 06 December 2014 - 02:22 AM


I agree about it might be top heavy. Have lots of mounting options now (I wish there was a ball joint on the top of the ninja too - or at least holes to screw one in) so once I'm back in the water I can get it balanced. At least now the handles are very strong. The Carrier was definitely worth the 90€!

Yeah the long camcorder style definitely lends to better balance. I have the DiveXtras deluxe camera mount for my DPV too. But my local centre isn't happy with me having all that kit on the boat at one time. LOL

Finally got home to see if indeed it was the right size :)


Had to buy some more Nautical pieces (3 flat bottom ball joints and 2 mounting bases) 


Bneed to spend some more money, as as predicted cold shoe can't be used, so need a YS female base that can screw directly into a M5  bolt hole)


But super happy with the result. Compared to trying to make something - or upgrade to the NA-GH4.

93€? It seem like a perfect candidate forma a DIY project :)
Actually even a pro metal worker could ask far less.



Yeah 93€ might seem steep, but that includes delivery.


I did think about getting one made up, but thought lets give this a go first.


I've got a 3D Printer, but that only prints up to 20cm, so couldn't make one on that..

Posted by thetrickster on 02 December 2014 - 11:03 PM

As the Shogun was mentioned earlier by Peter. I've seen some photos of the housing unit on Facebook. Gee. It's BIG!!

Heard Atomos have delayed it - AGAIN....

Makes my ninja2 look tiny!

#350465 GH4: Panasonic 7-14mm f4 lens in a Zen 170mm port?

Posted by thetrickster on 18 July 2014 - 01:37 PM

Thanks my video :)


I was purposely flying past rocks to see how well the lens would cope with corner sharpness - yes the 16:9 aspect will help and so too the 4k crop.


But I couldn't be happier with it. I have the 12-35mm also - but I think even at 7mm (with the 4k crop) is 'just' wide enough for wide angle shots

Tell me about it, I'm off to Sri Lanka on Tuesday to dive HMS Hermes with my GH4. Talk about Kit... CCR, Regs, Camera, Dive Kit, Spares, Lights, Chargers it just goes on and on!!


Quite agree about the inertia, as to screen size maybe I'll be a convert once I've seen a Shotgun in the flesh :)

Personally for me, before diving in, you have to make a choice...Macro, CFWA, WA and from there you select your lens for that dive. Anything other than this is a compromise, especially behind a flat port.

White Balancing was done very easily using the sequence: WB Button, UP Button and then Shutter, while pointing at a Amphibico White Balance slate. It never gave me any issues from 3m to 20m. Really fast, accurate and no problems. Can't see it needing that slate - Im sure it will work with any - it won't be for a couple of weeks, but I my old PADI Photography slate somewhere - I can do some comparisons for you - if you can wait :)


Colours have been adjusted in FCPX as I'm purposely running the GH4 in STD with every turned down (-3,-3,-3,0) and then I have a Preset which I've created to bring up the colours in FCPX - I'm not spending any time playing with it scene by scene, adjusting this and that - literally I imported the first couple of clips, got them how I liked (Saturation, Constrast etc) and saved the preset and then applied it to all the clips - so not a big workflow issue. I do need to spend some time with the other colour profiles (CineV etc) and see how much difference they are - and see how the camera responds to have for example the saturation turned UP on the camera.. these will be for when I have a tripod so I can really get some good comparison shots. I do believe with a correct profile on the camera a good white balance, no NLE adjustments could be needed.

Color: Global 0%; Shadows 3%; Midtones 16%; Highlights 0%
Saturation: Global 0%; Shadows -12%; Midtones 4%; Highlights 47%
Exposure: Global 0%; Shadows -30%; Midtones -13%; Highlights 0%

One thing I've played with and forgot to reset was master pedestal its set to +12 on the camera (doh) - hence the minus exposure / sat adjustments


Running 4K on my little 11" MacBook has been quite amazing too be honest (apart from the initial import and transcoding the proxies!!)

I think the GH4 housing will answer a lot of issues with the NA-GH3, stability, trigger etc..


But I'm not sure if I could justify the expensive of upgrading thou.... I've already fitted the vacuum system to mine and from looking at the NA-A7R, which I'm told the NA-GH4 will feature similar improvements, travelling with it will be harder, as at the moment I can strip the housing off the tray with just two screws.


The trigger for me is the biggest benefit, why can't Nauticam release an add-on for the Flexitray to benefit all 'non trigger' housings... If only I had a 3D printer (and the skill to use one!)


Looking forward to seeing the housing - and this new glass dome - which I believe is 180mm, add the fact the focus knob - now that is something I could be interested in...


Talking about focusing - we need a focus ring for the 7-14mm, as I'm not sure about you, but I'll my 7-14mm at 7mm all the time, so the zoom ring I have is pretty irrelevant.

The 170mm is bigger than i thought!!



Hopefully getting in the water this coming Sunday or Monday.

Not sponsored to do/say this....

But, Alex and UWVisions are exceptional - it does pay to have service, not just price. Especially for something that needs constant service, care and spares!

My wallet is still warm from the last time I called him. Lol.

#347381 Video Recording Formats AVCHD vs AVCHD Progressive

Posted by thetrickster on 07 May 2014 - 02:11 AM

Stuart, I agree completely with you.


My reasoning behind my comment, is that to keep the shutter angle at 180, for a 50/60fps vs 25/30fps you would have to double the shutter speed (so losing a stop) - so to compensate you would either have to open the aperture or increase the ISO to keep the exposure correct. Hence my comment about running a lower fps and so keeping the ISO low(er).


Thats what I believe anyway!?
