In Topic: Who is excited about Blackmagic Pocket Cinema 4K?

It really is a bit of an odd form factor, isn't it?

 

I can't see this as being all that useful hand-held since the monitor doesn't swivel out or even tilt -- and without an evf, can't really use it like a DSLR. Given how wide it is, it's not going to work great on any of the one-handed gimbals. Seems like this is meant to live on a tripod..

 

Whoa!!

 

Its gonna be a big housing! (But obviously you potentially don't need an external monitor...)

This does seem very promising if Nauticam makes a housing for it. Would be a great compliment to the GH5/GH5s line for video. Wish they had implemented Prores RAW if it really is that much more computationally efficient than cDNG/compressed cDNG (which only Davinci Resolve really supports). 

 

That said, one annoying aspect is the form factor and consequently the form factor of the housing. It's nice to have a large monitor built in, but it's limited in the same way that the camera monitor in current DSLRs is -- no easy way to see it from above or adjust the position. Similarly, a longer-style housing like C200 or Red housings would be nice from a trim perspective. 

 

But there's no denying this brings a lot of bang for the buck. Makes an upgrade to a C200 or EVA-1 + Atomos Ninja V a lot less appealing in some ways.


In Topic: Best m43 zoom lens for WWL-1?

05 April 2018 - 08:54 AM

Yeah, I've also used the 15mm f1.7 (in my case the DJI one, but I'm pretty sure it's just a rebranded Panasonic) in the 29mm macro port. Works a treat. The WWL-1 in it's native form is a 67mm thread, so you could screw it in directly. But I think most people commonly use it in combination with Nauticam's bayonet system, which requires you to install a bayonet mount on the port and a corresponding bayonet mount on the WWL-1.

 

It's probably not listed in the lens chart for Panasonic because noone thought to test it? After all, with the WWL-1, they were targetting 28mm equivalent lenses, so they tested the Panasonic 14mmF2.5 initially as the prime.

 

Incidentally, the Olympus 25mmF1.8 also works in the Macro Port 29 in combination with the WWL-1. Field of view is something akin to an 18mm lens inside a dome port (i.e. the Olympus 9-18mm at the wide end). And I think the Olympus 45mmF1.8 also works in the same port, though I don't see why you'd want to use that on a regular basis. 


In Topic: GH5S Better colour

05 April 2018 - 08:32 AM

Yeah, the vectorscope comparison is pretty interesting. Having less of a green tint could definitely benefit underwater footage, but the differences aren't astronomical -- I imagine you could tweak the GH5 to be pretty similar to the GH5s just using the G-M and A-B WB adjustments..


In Topic: Underwater Monitor for Panasonic GH5

29 March 2018 - 09:23 PM

Yeah. Its not small (due to float arms) and finding a bag that it fits on the boat hasnt been successful..


Yeah the window. The angle of the screen seems to give me really strong reflections of myself. Im sure some matte protector will fix it


No. I havent. As I havent purchased any V60 or V90 SD cards that work at 400Mbps. Dont see the point as I do it straight to the SSD.

But the Inferno at 4K@60p is 1660Mbps vs the 400Mbps internally and 10Bit too. Which I do find a big difference (you would get that benefit with the internal 10Bit vs 8bit also)


If I didnt have it from my GH4 setup, I personally think recording internally to a V90 card and running a cheaper / smaller monitor would be easier. But I got it so Ill use it and I dont regret, as it is a joy to use underwater :-)


I dont know the weight of the shogun part. But for reference:

1x NA-GH5
1x NA-Flame
1x Macro35 Port
1x WWL-1 (including its buoyancy collar)

Requires 2x 70x220mm Float arms and that isnt even enough to make it neutral.

 

You should be able to film 10 seconds or so at 400mb/s on fast UHS-1 like the Extreme Pro cards if you have one of those. Give it a try -- should be enough for comparison purposes :)

 

The size of the files is indeed a big difference, though in all fairness the internal codec maxes out at 400mb/s at 30fps -- which should be 880mb/s in Prores HQ, so only about 2.2x the size. The prores will definitely be easier to edit -- I usually end up having to transcode the 400mb/s all-i from the GH5 to edit smoothly in FCPX. But if there's no real quality gain, then I'd much rather stick to the smaller internal files and use proxies for editing where necessary.

 

Boyancy wise, I have a similar setup -

 

1x NA-GH5
1x NA-Flame
1x Macro 29 Port
1x WWL-1 (including its buoyancy collar)

1x 70x220mm float arm

 

This is slightly negative still, though probably only a few hundred grams. Sounds like the Atomos housing, if negative, isn't massively so.

 

What kind of battery life are you getting out of the Atomos?
