#351505 Shark Week: New season, same nonsense!

Its awful - 'Megalodon Lives' - faked footage, actors as 'biologists', non existent news stories


#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.

Hopefully getting in the water this coming Sunday or Monday.

#347848 US custom charges to UK?

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!?

#345965 Rig buoyancy-

Posted by thetrickster on 10 April 2014 - 06:32 AM

I tried both digital and analogue luggage scales but the rig just wasn't heavy enough to get a me reading. 


I had this problem... it turns out you can get luggage scales that have difference accuracies


What you need is :

http://www.amazon.co...ggage scales 5g


I got a set of these locally (and a Chinese Bizarre cheap shop) for like 5e. its accurate to just 5g. Weight mine, bloody -1.170kg negative!!!

Any word from Nauticam on whether or not the NA-GH3 will work with the GH4?


Its just the control dial that is the issue, it will fix size-wise - its just the locking button in the middle of the control dial that is the issue.


As to an external recording - hearing that Atomos at NAB will have something to offer all these 4K users...

#344262 Cage diving with great whites

Posted by thetrickster on 09 March 2014 - 06:34 AM

You will have a big viewing 'window' in the cage (big enough for a small shark to get in!) - plenty of room for a 7" dome :)
