Upcoming Panasonic GH-4K

[thetrickster 328]

Did I read somewhere that there are very long delays on that Zen 170mm port?

 

Hi Nick,

 

Yes - its been a VERY long delay in the 170mm domes...

 

The glass element isn't made by Zen (which in turn is the same company as ReefPhoto), there has been a problem with the production of this part. Zen have now started receiving their glass elements and are now making up the 170mm domes. But it looks like there is a big back log of them...

 

My 170mm dome has been on order since January, yet I still don't have it. Luckily my distributor (the rather excellent UWVisions in the UK) now has my 170mm in hand, but alas I'm waiting for a couple of other bits to arrive, so Alex can send the whole lot on to me.

 

But it looks like the 170mm domes are now going off the production line but very slowly and are on a first come, first served basis

The last email I had from Zen:

 

​I wish I had more information for you but this is an unexpected production delay combined with very high demand - I imagine it will be quite a while before we have these domes in stock. I would recommend placing an order with one of our dealers and that way they can notify you as soon as they start shipping again.

At the moment, the 170mm (unless you go for a 200mm+ dome and a Subal to Nauticam adaptor) is the best dome for the 7-14 / 12-35mm.

Is this the Zen port you are talking about Richard?

Yep, Thats the one Pete.

Following on from Edmonds issues with HDMI,

 

Here is a list of all the working and non-working modes with the GH4 and Ninja2

 

Ninja2 Formats.xlsx

[thetrickster 328]

Following on Edmond and Ryan's post about modifying the housing (or not).

My observations:

1. Camera fits 'just' with the new larger Eyecup - There is some friction on the housing AF/AE button internals, as you close the housing, but once closed there is no issues. I have ordered a OEM GH3 Eyecup (Part No: VYK6B43) for less than €8 inc delivery, to save this as I'm not really happy with leaving one off either.
2. Without modifying (a la Edmond) the push down dial, you cannot operate the Mode dial. So need to set before closing housing. It has been confirmed that Nauticam will be releasing an upgrade part kit to get around this issue - at some point.
3. Everything else works as it should like a GH3.

A fix for the Ninja2 Issues @Edmond?

 

I don't have my Ninja2 with me at present, but I do have my GH4 and I've been having a dig through the menus and settings - and come across this:

Maybe that is the solution?

[thetrickster 328]

Doesn't work :-(

 

I can confirm that the GH4 is outputting incorrect framerates at the HDMI port in relation to those it's recording.

1080p25 is outputting 1080p50

1080p30 is outputting 1080p60

 

1080p24 is outputting CORRECTLY at 1080p24

 

Plugged the GH4 directly in to my TV (1080p) and it tells me what it's receiving (1080p60) when the camera is recording 1080p30

At the moment, the 170mm (unless you go for a 200mm+ dome and a Subal to Nauticam adaptor) is the best dome for the 7-14 / 12-35mm.

Can you help me? What's the difference in comparison to the Nauticam port?

[thetrickster 328]

The zen 170mm is glass vs the Nauticam is a Plastic (for me I prefer the weight of glass)

 

That is the main difference in price.

 

Being a slighter larger dome, I'm hoping that it will be slightly sharper in the corners too.

 

Another benefit is that is easier to pack.

Thanks a lot Richard!

[Pete L 48]

Does the GH3 housing have the same port opening as the 7D housing?

Just wondering if I could use my 8inch acrylic dome on the GH3 housing with the 7-14mm lens?

[Pete L 48]

One other query, if the 8inch dome can be fitted, is there any reason why the 12-50mm lens wouldn't work behind it? Apart from not being able to access the macro button of course?

Would anyone know what extensions I would need to use for the 7-14 & 12-50?

[thetrickster 328]

Hi Pete,

 

The NA-GH3 housing is within the Nauticam's 'Mirrorless / Mini' group of housings and ports. These are smaller than the 'DSLR' ports, which your 7D Housing uses.

 

I'm not 100% sure, but I don't think there is an adaptor (I can't find it on the Nauticam website) which you can use for using the larger ports with the Mirrorless port system. The only issue I could see, is if there is an adaptor, it would act like an extension ring...

 

As to the 12-50mm, 12-35mm (which works behind the 170mm dome) is 96mm extended, where as the 12-50 (I read) doesn't extend while zooming (83mm), so I would guess it would work.

 

(the 12-35 / 7-14mm need the Mirrorless 20mm extension ring for the 170mm Zen dome)

Thanks again Richard

There is a release for the GH4 here in Sydney this Saturday at a major camera store so I am very tempted to head down & pick one up.

Just want to finalise all options before I lay down cash.

As I said before, still awaiting my 170mm dome, but really looking forward to getting it under the water

 

Might venture out this weekend, with just the 60mm and macro port

Here's a quick GH4 video, shot using the Nauticam GH3 housing. Shot this week by Laz Ruda. This should play at 1080p for you if you click through to the vimeo site.

 

[thetrickster 328]

Saw that on Facebook... thanks.

I also saw "we'll have more news about this and a new GH4 specific housing soon"........

We still getting an upgrade kit for the NA-GH3 to enable use of the control dial....?

I don't have news on that just yet. It is being worked on, and I think if it is possible, we'll do it.

Which store in Sydney? and at what time. Also tempted

[Pete L 48]

Digital camera warehouse on Canterbury Rd. I think it was from around 10am to maybe 2 or 4pm.

They are having Panny reps there & doing some deals I believe.

I know that they are selling them for $1797 on the day instead of the $1885 they are advertising.

Still very undecided on this camera myself.

 

I am going to hold off for a few weeks until some have used them underwater as I want to see how they handle banding & also grading with the 8bit 420 colour space.

[edmond320 26]

Just return from R4, this is a very short video filmed with GH4 in 4K mov.

Will take a few day rest and start edit the rest shortly.

 

Cheers

Edmond

[thani 86]

Very promising indeed

Looking forward to the full version.

 

Is it possible you post on Vimeo?

It holds the quality better, I believe.

[Pete L 48]

How did you find it Edmond?

Would you care to post up your thoughts please?

Cheers Pete.

[Pete L 48]

Just watched the video Edmond, it looks good.

What lenses/ports did you use?

I couldn't see any banding in the blue water from watching it on my phone.

Looks very promising indeed.

[RWBrooks 26]

Good to see someone has got this underwater.

How did you find the focusing? Where you using an external monitor? How much post did you do on especially the wide shot?

Can't wait for a write up!

 

Cheers

Lots of damage done to the video by YouTube. Could you please post a full 4K clip.
