#399345 Anybody using Leica 12-60mm for video?

Posted by Interceptor121 on 13 September 2018 - 09:59 PM

Interesting findings. Why would Nauticam recommend a 2mm shorter extension (67-65) for the longer Leica lens with the same 180mm (7) glass dome port? Does this make since?


Sell more parts? Don’t really know 2mm are unlikely to make a substantial difference. Ergonomics maybe? How does it work for you?
On paper considering the port is the same it doesn’t matter.
Likewise for the 6” wide angle port it works anyway and is more compact than the 7”. Will you see a difference between them with the 12-60mm? I don’t think so. 12mm is not that wide and Nauticam is happy to recommend 3.5” wide angle ports with extensions for other olympus 12mm lens. Port size has to do with focus distance and all those lenses focus pretty close so don’t need large domes

The landscape land shots look great. Clearly the dynamic range is there.
For underwater shots did you do any slow down 30 to 24p or similar?
I cannot see any bumps from lack of stabiliser but surely you have trimmed them out or otherwise did you use any stabiliser in post as the footage looks good

#399147 Who is excited about Blackmagic Pocket Cinema 4K?

Posted by Interceptor121 on 07 September 2018 - 11:47 PM

The only thing I’ve learned from watching that is the BMPCC4K does indeed have the ability to Manual White Balance - which Incepter asked earlier. However as you would be shooting RAW CNG you would be setting in post I presume.

It’s a chunky camera for sure.

Unboxing videos = “I got one early, unlike you” LOL [emoji38]

I believe when you shoot in ambient light white balance is always a good thing to do even unless you are using lights
When I take stills I white balance even with raw
Good news on the white balance for this camera and the interface appear useable underwater certainly more than Ninja V. May work well for macro shots on tripods but not as a fin about camera in my view

8-18 not in scope for now so am left with 6” for 12-60mm and no extension...

Quick update as expected the leica 12-60mm works fine with the 6” wide angle port. I have tried also the mini extension 30 the lens fits in it however am unsure the gear will because of the secure latch that holds the extension to the master port.
I will post some shots when I have a minute to compare extension and straight port
In terms of sharpness I took some shots at f/2.8 from what I see performance is more than satisfactory

#398917 Panasonic 8-18mm, which dome?

Posted by Interceptor121 on 31 August 2018 - 10:53 PM

I've taken the plunge and picked up the 7" acrylic Nauticam dome port today (I'll be able to claim back the VAT ;-)
The removable hood on the 8-18 lens is way too big to fit through the "extension" part of the dome port, so the hood can't be used anyway...
It is much bigger than the 6" (sorry for pointing out the bleeding obvious but there is more difference than I expected.) It appears to be  a bigger section of the same radius sphere as the 6"
I'll be getting it wet in a couple of weeks time, on my first trip to the Red Sea since 1993! (I mostly dive in IndoPacific).
 
I'll also try it with my Pana 12-35II, usually used inside the 6" dome for video and portraits, to see if I can just take one dome for both on future trips... Living room testing suggests that it'll be fine in the 7" dome; it doesn't appear to vignette. It does extend quite a bit on zooming (photo below shows it at 35mm) and only just fits inside the 6" dome in any case (the hood must be removed on this lens too btw).
Hoping for decent baggage allowance on Egypt Air...

If it doesn’t vignette the 12-35mm will work fine in the new dome. At this stage I would consider selling it and investing in the leica 12-60mm that is generally a more useful lens and you can fit it in this dome too

Also despite the optical impression the 7” is a cut of a 14” dome while the 6” is a cut or a 12” dome so the new port is larger...

Reef photo kindly offered to take a side by side

From what I can see the 6 wide angle port is less curved this can still work fine with the 12-60 provided you find the ideal distance. The 7” port is 35mm longer so you need a 30mm extension
The good news is I have both 6 dome and 30 extensions so will run some tests soon

#398833 Panasonic 8-18mm, which dome?

Posted by Interceptor121 on 29 August 2018 - 12:36 PM

Yes perhaps it will, but I'll do some testing and report back in a few weeks.

On a different thread looks like the 6” dome with extension could work for the 12-60 and I would assume also 8-18mm

#398826 Anybody using Leica 12-60mm for video?

Posted by Interceptor121 on 29 August 2018 - 10:51 AM

I was extremely interested in this lens when specing my new GH5 setup.  I contacted Nauticam about it, and was told the "Panasonic 12-60 is fantastic, but it doesn't play as nicely with macro optics due to the lens' physical construction with lots of movement through the zoom range."

 

So, I ended up up with the 12-42 PZ lens, with the WWL-1 instead.  So, I have no experience with that lens, but would be very curious about it, if you decide to try it,

 

Hope that helps.

 

Also I read now your original post on winter musing. The 12-60mm with dome is not a solution for macro dive. For those you would need a flat port and in my view unless you want to dive with a 60mm the 14-42MKII or Power Zoom plus diopters. So if you want one combination that covers everything possible with a single lens this is a 14-42 with flat port and wet lenses

I already have the 35 macro port and I have wet lenses however as I am considering the 8-18mm that needs the 7" port I was thinking of housing the leica lens too.

This lens is a better lens than any of the 14-42 zoom lenses and although it won't do macro as the 14-42 with diopters it will be ok for reef scenes with medium size fish not for wreck and not for macro but for plenty other options in the mid-range a better choice

Surely not exhaustive choice and not compatible with wet lenses but same holds for the 12-35mm and all larger zoom lenses of higher quality




#398820 Anybody using Leica 12-60mm for video?

Posted by Interceptor121 on 29 August 2018 - 08:25 AM

I use this lens topside with my GH5 and it is great. I know is compatible with the nauticam 7” dome but am unsure if you can zoom through
The focal range is very interesting as it gets to 120mm and with ex tele you have a further 1.4 zoom in 4K with a working distance of 24cm. It covers 36mm horizontally as minimum.
I have an upcoming trip to Egypt (turtles dolphins and hopefully dugongs) but except turtles nothing coming to near and am considering this lens because it has great stabilisation

#398807 Panasonic 8-18mm, which dome?

Posted by Interceptor121 on 29 August 2018 - 02:44 AM

 
Yes, I'll be using the 8-18 for mostly stills, and perhaps for blue-water video (ie not too close up to reef so the edge effect is less evident, eg mantas etc).
I currently use my 12-35 for general uw video, so I'm wondering how that will fare inside the 7" Nauticam dome (which I have settled on by the way, due to availability, timing, cost and portability ;-). It would save me carrying both domes around (although its always good to have backup...)
 
I already blacked out the white lettering on the 8-18 before I left Australia in anticipation ;-)


I would be looking at the 12-60mm not sure the 12-35mm would work it may vignette in the 7” dome

#398728 Panasonic GH5 and mini flash DMW-FL70

Posted by Interceptor121 on 27 August 2018 - 12:52 AM

(a bit late to the discussion sorry, been travelling :-) 
I've been using the FL-70 for a while and find it very good. I previously used a GH4 so was used to the battery drain consideration and the FL-70 hasn't yet caused me to run out of battery on a dive...
I also have the Nauticam LED trigger, but I prefer the flexibility of having TTL if I want it during a dive, and this seems to outweigh any need for faster recycling.
Only available from Japan I believe?

Yes I have ordered it in Japan but this is really a great addition to the camera not just underwater. Works well with close shots on land especially in shade over a bright day when you don’t want to carry a larger unit
Worth every cent of import duty

#398699 Panasonic LX100 M2 announced

Posted by Interceptor121 on 25 August 2018 - 11:53 PM

Yes, the review I read so far say the M2 upgrade is for photographers. I shot video so the upgrade doesn't benefit me much. So I'm still going to keep an eye on the Black Magic Cinema 4K, or GH6. GH6 could be announce late next year, before 2020 Olympic.

The BMPCC is the same sensor of the GH5s and has no stabiliser
In my view the GH5 somehow saturates the need of underwater video. You have 10bit capture on dual SD slots at 400 mbps. Other than signal noise ratio I see no major weaknesses of this camera and already 99% of users do not own computer hardware to grade it properly. The only issue that would be nice to address is a larger screen 5” with at least 600 nits. However I don’t think Panasonic will see a benefit in doing that

#398683 Who is excited about Blackmagic Pocket Cinema 4K?

Posted by Interceptor121 on 25 August 2018 - 01:38 AM

The official documentation has been released
The BMPCC has the same sensor of the Panasonic GH5s it does have a white balance button but it is unclear if you can set custom white balance
It has no stabiliser and one SD slot and one cfast slot
It is unclear which lenses will support autofocus
I believe the key strength on land is the ability to connect a usb drive to record and with the 5” screen this could be a killer
However if white balance cant set a value this could be painful because cameraraw requires very expensive cards and without a stabiliser quite a bit of post processing to be excepted
On land this looks very promising underwater we need to see

#398378 Panasonic GH5 anybody using 400 Mbps All-Intra?

Posted by Interceptor121 on 13 August 2018 - 05:25 AM

I have just finished decomposing the various codecs used by the camera to record on the memory card and I have to say I am disappointed.

 

I had previously looked at endless comparisons between the various codecs to conclude there is not much difference in it but now that I have looked myself I am even more frustrated. I had hoped that the 150 Mbps 422 10 bit color codec was going to be enough for HDR but frankly this is really poor beyond my expectations obviously the camera internal processing is not strong enough to compress this signal real time and make it usable.

 

If anybody fancies looking into super technical stuff the findings are here http://interceptor12...rding-settings/

 

I am now wondering if I should fork some serious cost and invest into V90 memory cards to use all-intra or should I just not bother entirely and use the 100 Mbps codec I am curious to see if anyone has experience with all intra at UHD resolution? I already know myself this has not enough headroom to compare with external recorder but just wanting to check it out

Posted by Interceptor121 on 04 August 2018 - 04:09 AM

Good luck with your set up
I think the 5” monitor is a winner I wish Nauticam made an housing for the Ninja V as 7” monitors are really not a good fit for a micro four third camera
