I wonder when we the first housing will be announced. I cannot believe that someone won't make a housing for this.

If it's possible to remotely control the camera via LANC protocol or USB, I guess it should be very easy for Easydive to produce a controller for one of their housing.

Here is a thread that compares the BMD Pocket 4K to the GH5. I’m not really impressed if the P4k is similar to the GH5 in low light performance :(

Depends on the price of the housing, the Pocket Cinema 4K probably is not that attractive due to the fact that it doesn't have IBIS. The Panasonic full frame has IBIS, even thought it will be twice the price of the Cinema 4K, but the Panasonic full frame seems to be more "future proof" for a while in term of image quality.

well, may depend on the capabilities of the user. This LL-stuff looks pretty impressive

Some side by side test with the GH5s

 

Which is which...

Today’s cameras produce very nice footage already and as the BMPCC 4K is supposed to have the same sensor as the GH5S, the difference will come on how BMD has manage their color science.
Also despite the BMD camera looks like a hybrid camera, it is not one. It still have the original BMPCC heritage. You’ll have to learn how to work with it.
What make me want the BMPCC is the BRAW for what you can recover in post, other than that the GH5S offer more practical feature for easy shooting.
What’s your first impression after looking the online tests available?

First impression... Panasonic are over changing us for the GH5s by a $1000...

 

As to image quality, at the moment from the examples I've seen, I can't see any real differences against the GH5s - nothing that would make me start offloading my GHx gear.

 

BRAW will be interesting, but still feel both Panasonic and BM are getting almost all of the sensor info already... but look forward to see some BRAW vs ProRes soon.

 

For underwater, the bigger screen (it being tilted also) - might make it great for underwater as it negates the need of an external monitor.

The fact that they shoot in a high-bitrate, high flexibility raw format (and especially Black Magic Raw, which is an excellent compromise between versitility, file size and computational requirements) is a HUGE plus for this over the GH5/s underwater imo.

 

The screen would be another big benefit underwater, and may eliminate the need for an external monitor while keeping the whole rig streamlined.

 

Compared to this, the limited autofocus ability shouldn't be a major problem underwater. The battery life is not great, but should be enough for one dive. It's also nice that you get a choice between different recording medium (SD cards, CF and SSDs through USB-C).

 

Of course.. we need a housing. And hopefully one that isn't three times the price of the camera. If that comes out, you can bet I'll be testing this guy's capabilities underwater.

 

I think this would pair up really great with the new 10-25mm F1.7 lens for general wide angle shooting underwater also. Rectilinear 20-50MM is an idea focal length range for video underwater IMO -- enough for wide angle scenic without excessive corner distortion and also close-up shots of anything non-macro.

What do you guys think of the shortcoming of not having IBIS? I know a guy who said the IBIS in the GH5 made shooting video super great. Those who have GH5 and GH5S, how bad is the IBIS difference?

 

I have been shooting video seriously for about 3 years, most time I can get the footage stable depends on dive condition and how relax I am. However, 90% of the time I still get micro jitters shake regardless how I configure my rig to make it neutral/slightly negative. IBIS would have taken care of these micro jitters.

The difference is extreme on land for Dual-IS vs just lens IS if you for example do some recording while walking.

 

But I still feel, if you get a balanced rig underwater the GH5s with an optically stabilised lens provides great results.

 

Got a couple of weeks of back to back diving end of Oct - its one of the thinks I'm going to have a play with.

would be good if you could test dual vs single IS Richard


Cooling might be another issue. The camera uses a fan for cooling which will be recycling warm air inside a housing. Even if its an aluminum one. Use to have overheating warning on RX100 Mk4 when was shooting 4k even on an aluminum housing.

There is a world of difference between dual IS and lens IS
Anyway the cooling and battery issues can be solved using a recorder with a battery pack underwater but this will make this set up expensive again
Anyone asked Nauticam if an housing is planned?

I have both. On my trip to French Polynesia I used the GH5S underwater. It looked ok when casually checking the footage on a notebook during the trip. But during editing back home on a big screen iMac, the Micro-jitters were very apparent. and with strong currents you could „see“ the drag more than what I got with the GH5. I could fix some issues in post-stabilisation, but many not.

I‘d certainly go for the stabilized GH5 again next time and not the „s“.

I have asked nauticam. They will be looking closer at this once they have a unit they can test.

I asked for slots for large external batteries and ssd drive. Essentially flat mount under the base of the camera something like the sony cameras currently have and they took that feedback.

Im sure this camera will be housed and they arent far away from doing it though i havent heard anything for quite a few months.

That's just what I thought with the GH5S short coming, the BlackMagic Cinema 4K will have the same issue. The micro jitters could be smooth out in post such as using warp stabilizer, but you would have to sacrifice 5% of resolution to crop. Ideally a camera that do not have IBIS should shoot at 4.5K so there would be plenty of room to crop for stabilization in post.
