Sorry for the slow response. I was out diving in the South China Sea with my NA-GH4...

Seems like you have the answer you need.

Initially I bought the M16 vacuum valve for the larger port at the front, thinking that the M16 port is more "out of the way" of the top controls. I use the Mode dial often to flip between 3 custom settings that I have created for different shooting situations and to bring the settings back a known starting point whenever I have been fiddling with some of the controls.

However, once I have the Shogun in a housing, I will most likely have to buy the M14 vacuum valve for the rear door port and use the front M16 port for the HDMI cable, as the M16 port is closer to the camera's HDMI socket. I'll cross that bridge when I get to it.



Hi Peter,


Thanks for the reply.

My Nauticam housing and the rest of the toys will arrive in a week, I hope.

Can't wait to mess with it.


I tested the GH4 with 12-35mm Panny on land. Using 4K, 3840 pixel, focus is slow but it hunts a bit even when subject in middle field.

Also being a camera type lens and not a camcorder or say an RX100, zooming on a subject with bright background will cause insane flicker on the bright areas....ha ha ha.


Since it is mirrorless, I wonder why the video focus is not as smart as my Sony NEX-7 and flicker free like NEX-7 when zooming.


Anyway, overall I am happy with new nice toys to play with....


Thanks n Dive Safe


In Topic: GoPro, ActionCam X7 or ?

01 August 2014 - 12:55 PM

Hello Dp,


This is quite an old post but in case you are still curious.


X7 is actually ISAW Extreme.




I got both the X7 ( now dead, bad unit I guess ) and the ISAW A3 Extreme ( i got 2, in case 1 went bad again....LOL )

My advice is , get the GoPro HD3+ Black and set Protune + Camraw and be happy. Choose its Dive Housing 60 meter rated or its the older HD3 original housing actually under a new name. Yeah, get the LCD BacPac too.


The X7 or ISAW A3 Extreme has built in LCD screen and they are so dark, you go blind underwater with it, unless it is a night dive. You can't remove the LCD screen, it is there permanently.


The 1080 50p ( or 60p ) resolution on this camera is very bad. The 25/30p is good.

At 50p its like scaled up and not true 50p.

Its so called UW white balance the Aqua is useless for your kind of dive.


I have not dove the X7/ISAW beyond 10 meters, was only doing shallow test dives and retire it after I seen the LCD screen is so dark and I can't see anything. Not having an equivalent CamRaw like the GoPro is another turn off for UW use, its hard to color correct it later in post.


Its exposure is jumpy too,  not so smooth. Kind of small flicker at times.


Wifi smartphone or tablet Apps , the GoPro is light years ahead.


Hope that helps.


I have the Sony Action Cam AS100 too, if you considering it.

Again for UW use, stick with the GoPro HD3+ Black and be happy.


Happy shopping....

I have the Nauticam NA-GH4 right here in front of me 


Hi Peter,


May I trouble you a bit please.


Is the assc port at the door a M14 size ? The front left at main body surely is an M16 for HDMI.

The Nauticam user manual stated the assc port at the door is M14 but Backscatter and Reef Photo reccomended the vacuum valve of M16 size.

I want to use the vacuum valve at the door assc port and keep the M16 one at main body for HDMI.

I fear the NA-GH4 user manual has a print mistake on the M14 assc port size at the door.


Page 9, item 20



The exterior look for the port plug is always the same between M14 and M16, so me kind of worried.




Hope its not too troubling you.


Many Thanks


In Topic: Sony A7S for 4K - what a disappointment

13 April 2014 - 12:18 AM



I think its not totally about  "Half done right".

When an OEM has professional models above the consumer level, they need to protect those pro models. 

Pro model is where the $$ killing is made...I mean the buyers get stabbed here....ha ha ha.


Sony is loosing money as an electronic company, but their insurance business is making good money.




Black Magic is a good example of a company which it probably has nothing to protect, it only has so few cameras and they try to make

the best for these models......at a reasonable cost. But R&D need money. Small company like BlackMagic can not order sensors by the 500K quantity, so they will progress slowly but I hope they will do well.


Its quite the same like Nvidia graphic cards, the crippled some functions of their new high end gaming cards in order to protect the crazy expensive Quadro line which is used mainly by professional graphic station.


Recently FLIR did the same thing :


They sell low cost US$1K unit by locking its capability, while the engine-internal is the same as a unit costing US$6K ....ha ha ha.

Just firmware lock....holy cow.


Its all about busines, how to rip off more $$.

If your girlfriend or wive on day request you to get her a Hermes as below :



You will know that no leather will cost that much.....he he he....its the perceived image you paid for.


Dive safe.........
