#399985 Who is excited about Blackmagic Pocket Cinema 4K?

Posted by bubffm on 10 October 2018 - 02:00 PM

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 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“.

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 :(

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

#399671 10-25mm F1.7 Panasonic M43 Lens

Posted by bubffm on 26 September 2018 - 09:39 AM

In my wet dreams I always imagined a 9/10 mm prime lens.
In the past I used the Oly 12mm F2 on land and it's amazing. Underwater it's too narrow for my taste.

I used the Pana-Leica 12mm Summilux prime with a custom made focus ring in Triton Bay and it worked great. You can immediatly distinguish shots with this lens as compared to the 12-35 - which also a great lens btw but not comparable to the prime).

But yes for things like wrecks it would be too narrow but on reefs it was quite ok.

With Blackmagic RAW coming to this camera, this suddenly does start to look like a very interesting proposition. So no need to house a separate SSD :)


#399277 Diving with Gian Manta Ray - looking for constructive criticism

Posted by bubffm on 11 September 2018 - 10:21 AM

Some very nice shots. Well done!  


This is perfectly watchable as-is, but I assume you took the shots pretty much as they came out of the camera?  The shots look very blue, so I'd try to adjust the white balance a bit in post. Some blown out highlights on the white belly of the mantas, but I know their skin is very reflective and this happens easily.  Again, I'd try to play a bit with the exposure in the midtones and highlights in FCPX.


Of course it always depends how much time you want spend getting a clip out, but if your looking for constructive comments, these two points may be worth playing with.


NB: I love how that morey eal spit out that sea urchin :-)

I will never grasp the relevance of unboxing-videos...

Attached a little clip I've compiled from our dive trip to French Polynesia. I took my GH5s along this time but I did miss the stabilisation a bit I must admit...


Most shark footage form the Fakarava South Pass "Wall of Sharks" at Tomutoa Atoll. 


#399012 Nauticam vs Saga Flip Adapter

Posted by bubffm on 04 September 2018 - 05:42 AM

Is your bold-letters-key broken??...


I have used that Saga flip adapter on that very same Gates domeport for years. Works perfectly.  Who told you to put this on from the back with the domeport off?? That's total nonsense and will never work that way!  Just put your dome on the housing, put some silicon grease on the inside of the adapter ring (where the rubber-inlay sits) and just slip it over the dome's plastic hood. Dont move it back all the way, with the swivel in place, it should not touch the glas.

#398883 Anybody using Leica 12-60mm for video?

Posted by bubffm on 31 August 2018 - 04:18 AM


Ibid the 8-18mm. I don't think it will fit through the mini extension ring.


The 8-18 does not even fit through the extension ring without zoom or focus gear, let alone with gear installed.... 

#398228 Taxation of Housings entering Germany / EU

Posted by bubffm on 08 August 2018 - 05:21 AM



I did buy my Nauticam GH5 housing at Backscatter in the US back then, as it was not becoming available in Europe in time for an upcoming dive trip. I searched for the customs bill but could not trace it. However, what I do recall is that all-in-all I ended up paying around 10% more than what I would have payed buying in Europe.  


Therefore, unless there is a special situation (item not (yet) avail in Europe or super deal for a used housing etc...) I would advise you to buy in the EU. Also these custom rates are sometimes unpredictable depending into which category the officer places it. Also, unless your sender uses a high quality carrier (UPS the best for US-shipments), sometimes stuff gets stuck for a week or two in customs. Not always the best experience!


onderwaterhuis.nl in Holland is my preferred and highly trusted supplier in Europe for UW camera stuff these days.



#397823 DNC-7A(H1) VS SmallHD501

Posted by bubffm on 26 July 2018 - 12:23 PM

+1 on the DNC-5A Monitor. i really like it.


@Thani regarding the Focus Peaking:  Try playing around witht the Focus Peaking settings on the montitor.  I initially had the same problem that the peaking outline would disappear when I  switch to Autofocus.  If I remember correctly I have now set the "strength" of the Peaking outline to 23 and it now also shows up when switched to AFC.



#396788 Triton Bay, West Papua with Panasonic GH5

Hi there - thanks. Yes was using 2 Keldan 4X. Sometimes forgot to switch them off in WA, which created some more backscatter than I like at times....

So, for someone coming from the AX100, how hard was it to get used to the ergonomics of the GH5? 


Let me put it this way: If I could get a AX700-sized camcorder with the specs of the GH5 and a fitting housing by Gates or Nauticam, I'd definitely prefer a dedicated camcorder over the GH5 for its easy of use and better ergonomics.  But you get used to the trade-off's of a photo-centric camera body.



 I really like being able to go from shark or turtle-sized portraits, down to macro stuff on the same dive by zooming and using a flip in wet lens. 


My view: You can go from whale-sharks down to nudis on the same dive much easier with a camcorder due to the build-in zoom lens and macro-converters that you can swivel simply over the domeport. You could use wet-converters on the GH5 to achieve the same (Nauticam WWL with Bayonet mount etc..) but its somewhat more cumbersome. An yes, sometimes you miss shots on changeable lens system as you got the "wrong" lens on.


Having one button white balance on my right side handle is also really nice. 


You have manual WB right at your fingertips on the GH5 housing from Nauticam as well. More important is the quality of the WB you get underwater. Personally, I think Panasonic wins this over Sony.


There are now a couple test clips taken by the AX700 (or Z90, which fits the same Gates housing) on Youtube.


Have a look at this guys clips. he is a sort of "Gates Ambassador".  I have seen better UW-footage taken with the GH5, but let me know what you think.  



#396496 Panasonic GH5: what do you use to get the correct exposure?

Posted by bubffm on 16 June 2018 - 06:28 AM

So is it fair to say that nobody shoots with manual exposure?
I find manual very tricky unless you are in control of light for example during close up work

Like Richard, I am mostly fixing my shutter and my desired aperture and let Auto-ISO do the correct exposure. Works most of the time and with the GH5s theres now even more leverage. But for example shooting upwards into the sun, this method results in underexposed footage, ie you need to manage manually. Also out of caves / holes into the light is not turning out correctly.

Only slight drawback is that you dont actually see which ISO the cam is using at any given point in time. But you can set your ISO Limit to avoid overly noisy images.

But most of the time, Auto-ISO gives quite satisfactory results imho.

Ya, I noticed that a long time ago. Really apalling. They just need to spend a few thousand dollars to get this in order. Should be doable with all our fees....
