  1. Thani,

     

    Is 4K *REALLY* all that important ?

     

    My impression was that it was mostly hype. I suppose as time goes on it will be mainstream but how far away is that?

     

    If you could only chose ONE feature above any other thing, what would it be?


  2. Thani,

     

    You lead, I'll follow :-)

     

    I am pretty set on a Sony I think. That may change but for now its what I am thinking. Looking at an F23 2/3" sensor - no raw. The benefit is I can use a digizoom or digiprime lens on it. This is a lower cost way in at the higher end. Still not sure but reading and looking around a lot. The only problem is this means I would have to do white balance as I shoot - I wanted to go r a w to avoid this. Cant have it all I guess - unless you spend 5 figures. I am in this for the long haul. Once I commit to a platform that's it for me, so this is quite the thought process going on.

     

    The housing is going to cost far more then the camera.


  3. This is why I think the C200 is viable. For the price it offers a lot. Certainly better than the 1Dx MKII.

     

    But yeah....the best camera in the world is no good to you if it's out of reach.

     

    It all depends on what your end goal is - if it's for your own kicks then maybe it's not worth the cost of entry to the r a w world. But all things considered today's cameras are a bargain compared with even 10 years ago. It's all relative.


  4. I know its completely out of fashion to shoot a 2/3 inch sensor but wondering if anyone here can give me info on which lens range is ideal when shooting a B4 2/3" sensor camera through a dome port. I am considering a prime lens set - in 5, 7,10,14,20,28,40 and 70mm. Which of those is good for reef scenes and fish portraits?. I am not sure how 2/3inch sensor lenses compare to 35mm lenses in terms of FOV

     

    Is there an online calculator somewhere that shows the FOV between 2/3" and 35mm ?

     

    I seem to recall back in the day before the DSLR video boom, that a few here used to shoot on EX1 's and EX3's which i THINK were 1/2" sensors, so close to 2/3"


  5. The FS700 should on the list too. (fixed)

     

    "The FS700 sends the following RAW signals:

    • 4K RAW at 24/30/60fps, 120fps 3.6-second burst mode
    • 2K RAW at 24/30/60/120/240fps"

     

    I am only finding these cameras by reading and researching. If you know of one, please add it to the list.

     

    It seems like the options for RAW are (in order of cost)

    Black Magic range - model names?

    5D MKIII

    FS700

    C200

    F5

    F55

    C700

    RED - ??? Hard to know where to put this in the list - depends on the config as to cost.

    F65

  6. Re the Canon C200.

     

    Yes this seems to be the most sensible way forward if all factors taken into account.

     

    1/ New - not a second hand purchase like an older Sony F23 or similar (F23 does not do RAW but it's still the one of the BEST video cameras ever made)

    2/ RAW 12 bit 4K/30P (OK so not 12 bit 4K/60P...but still)

    3/ RAW 10 bit 4K/60P - beats the GH5 here as it records this internally and is RAW

    4/ Smaller camera so housing cost should be semi reasonable (is any housing cost reasonable ?)

    5/ Canon colours - some will like this, some won't.

     

    YES - lets hope it gets the attention of housing manufacturers - this may well be the most cost effective solution out there for 4K RAW at 12 bit.


  7. Hi Thani,

     

    Yep - i've seen that. I have been following you for years :-)

     

    I've keenly sat on the side lines watching you and the rest of the guys here going through all the machinations. It's been very interesting.

     

    Luckily (or unluckily depending on how you look at it) I got sidetracked with life events that took me away from all this underwater stuff. But time to get back to it. So actively looking again.

     

    At one time I was keen on the BlackMagic stuff - but its proven to be too unreliable. Just cant take the chance that the camera will flake out (all cameras can do this of course but BM seem to be especially prone to dying an early death)

     

    Thing is the older Sony cameras have had a real price crash. Some amazing bargains to be had if you dig a bit. Cameras that cost $200,000 USD 6 or 7 years ago can be bought, in good working order, for 5K today. These cameras are using SRmaster codecs - some variants out to tape, some out to digital recorders. Some are B4 format (with amazing HD lenses for cheap) and others are s35 in PL format. Those s35 PL lenses are NOT cheap at all, so have to figure that into all this.

     

    Then comes the housing. And that's where it stops. Unless I get a custom housing fabricated. Like YOU have done :-)

     

    So now wondering if it makes sense to get a housing made that can accommodate anything from an SR 9000 or an F23 (amazing camera by the way) up to an F35 (another amazing camera - this one is truely the most cinematic video camera ever made - but I dont think we are looking for cinematic underwater) and then the granddaddy of them all - the F65.

     

    Would it be possible to have a housing made that could take any of the above cameras ? They are all around a similar size (F65 is a lot "fatter" than the rest though)

     

    Then there is the whole RED thing, which I am still not keen on. But those prices for an Epic MX or Scarlet MX etc are falling fast too . Even an Epic DRAGON X can be had for 13-15K with low hours on it. Which only reinforces the old adage - put your money into lenses - not bodies.

     

    Its a great time to be setting up from scratch for a new camera.


  8. I do get that shooting RAW is expensive in terms of recording media and HDD space to store that footage. Its also a massive increase in workflow and time.

     

    But no free lunch and all that.......

     

    To me it takes a lot of time and effort not to mention cost to get out there and underwater. Once there I want to do the best I can, whatever the cost. The biggest single issue is white balance.

     

    I really really wanted to avoid RED if I could. I just dont like all the hype that surrounds it and while you might say, just get the camera and dont go near all that, you cant really avoid it if you want to network get ideas help and support.

     

    BUt after talking with Pawel its hard to go past his housing with the Nikonos lens attached to his housing. As crazy as it sounds I have been looking at the Sony F65. They can be had for 20Kish these days which is amazing for a camera that cost around 120K when new just 5 years ago. I know this is beyond the hobbyist level and so wont get much if any discussion here. But after throwing this idea around with Pawel, all in all its better to go with the RED Dragon (now down to 12-15K on the second hand market) as that then give me access to the nikonos lens series. At the end of the day, I'd say the lens is the most important part of all this.

     

    But there are a number of new cameras either recently out or coming soon. Moe and more options coming.

     

    The 1DX MKII looks good, but its not RAW. The GH5 looks OK. From there it seems to be a jump up to an F5 and then onto the REDS.

     

    The new housings from GATES for the REDs look good - can house a number of different cameras in the same housing - but land based lens behind a dome.

     

    Ahhh....decisions decisions. An amazing time to be into cameras....so much choice and prices getting more and more realistic, especially on the used market.


  9. 178 views and only 1 comment. Seems there is no love for RAW around here.

     

    Why is that so ? To me the idea of setting white balance in post makes up for the big file sizes and extra workload.

     

    Well, anyway, I continue to look. Been speaking with Pawel Atchel about this and he says, go RED for sure so that I could use his housing with a Nikonos lens mated to the housing .... Anyone have some thoughts to this approach rather than house an expensive PL mount land lens ?

     

    It really does look like the most sensible option is to go RED, as much as I didn't want to do that. I like the F65 which can be had quite cheaply these days, but to house that camera would be quite the task, not to mention handling it.

     

    I guess, if this were easy, everyone would be doing it.


  10. And another one to add to the list

     

    C700

     

    Priced at around $34k USD ($28k for body and $6k for OLED VF) and $2k more for the global shutter version, this camera is designed to be an “A” camera and workhorse on everything from feature films, broadcast TV, sports, documentaries and surely more.

    The camera is capable of recording 4K and features a 4.5K CMOS sensor with a global shutter version. The dynamic range is 15 stops for the non global shutter version, and 14 stops for the GS version. Somewhat surprisingly the camera offers an internal ProRes codec capable of recording in 4K resolution in 10-bit ProRes 422 HQ (unlike the Sony F5/F55 which with an extra $1000 board offers ProRes but is limited to recording only in High Definition resolution). Note however – the 4K ProRes codec on the C700 is only available up to 30fps but does offer higher frame rates in 2K regular and 2K cropped mode. (looks like maybe no pixel binning which Sony implemented for frame rates above 60p)

    The Canon C700 will also be RAW capable using an external recorder providing up to 120fps in 12-bit 4K RAW. The F55 features 16-bit RAW using the AXS-R5 recorder and with the newer AXS-R7 recorder can record 16-bit 4K RAW in up to 120fps, and 2K RAW in up to 240fps.


  11. So another one for the list

     

    Cannon C200 -

     

    Price is good for 4K RAW. As time goes on 4K RAW cameras are appearing and prices are coming down.

     

    To me, setting white balance wherever you want it in post has to be the killer reason why one would shoot RAW underwater.

  12. Yep thats one way of doing it.

     

    the F65 is damm cheap these days, but i shudder to think what it costs to house it.

     

    Horses for courses here - my dive location is at the end of my yard.....literally. So a huge hulking camera/housing is no issue for me. I will never be taking whatever i get anywhere else - just out of my house, down the yard and into the boat.......and thence into the water when over the dive site.

     

    So how much of the form factor makes you want to go 5D MKIII ? And is that because of flights etc and the cost of over weight luggage?

     

    It seems like the options for RAW are (in order of cost)

     

    GH5

    5D MKIII

    1DX MKII

    C200

    F5

    F55

    C700

    RED - ??? Hard to know where to put this in the list - depends on the config as to cost.

    F65

    Is that about right?


  13. Hi all,

     

    Well here we are in August of 2017.

     

    How far have things moved along in terms of shooting RAW underwater?

     

    What cameras are available that can be housed to shoot RAW?

     

    The RED's

    The Alexa's

    The Blackmagic's

    The Sony's (F7? F5? F55? F65?)

    The Cannons C 300MKII

     

    I think that is about it. Are there Any others that I have missed?

     

    Which ones can be housed (or more correctly - which ones have a housing already out there for them?)

     

    Lets daydream for a minute - if you had your choice of any of them, which would you choose?

     

    Thanks


  14. So at NAB the Ursa Mini Pro had new modules released.

     

    Specifically this;

     

    In addition to making DaVinci Resolve 14 better software for audio professionals, Blackmagic also announced new modules and functionality for the URSA Mini Pro:

     

    Bluetooth Capability: The Bluetooth tech in the camera has lain dormant until now. With Blackmagic's new app, users can now control settings and make notes remotely. This is ideal for situations where the camera is in high (jib, crane) or low (underwater) places.

     

     

    "This is ideal for situations where the camera is in high (jib, crane) or low (underwater) places."

     

     

    SSD Module: This module allows direct recording to your choice of approved SSDs for improved workflow with RAW files. The URSA Mini Pro is now capable of flexibly recording to CFast 2.0, SD UHS and SSD, making it one of the most versatile cameras on the market in terms of media. The module attaches flush in between the back of the camera body and the battery plate, and is powered by the camera itself.

     

    Native Nikon Mount: Building its repertoire of native mount options, the URSA Mini Pro has added Nikon to the list. The mount is a dumb mount—meaning no electronic communication between camera and lens (for aperture, etc)—but is ideal for the oft-used manual Ai Nikons

    Does this mean that housing manufacturers could now make a housing for the URSA Mini Pro? I believe the reason there was no housing for the original URSA mini was because all the controls were behind a fold out door, meaning there was no real way to be able to control the camera without having the fold out door open and thus not realistic for the camera to be mounted in a housing.
    But now the camera can be operated by bluetooth it should mean that the camera can be operated with its door closed thus housing size can be kept acceptable. So all it needs is a Bluetooth control module built into the housing. Should be doable.
    I wonder if we will now see a housing for the URSA Mini Pro .
    Here's looking at you Nauticam - if anyone can do this, it's them. Build one and i will buy it. Anyone else ?

  15. Does anyone use here use Black Magic Cameras underwater?

     

    I see from the front page news that Subal are now making a housing for the BlackMagic 4K Cinema Camera.

     

    How does this BMCC 4K perform underwater? Pros/cons ?

     

    I am sure there are plenty of readers here who would be interested to know more, so i hope someone can chime in with user related experience.

     

    Thanks

  16. The cost of the camera is nothing compared to the cost of the lens system!

     

    Everything I've read says the Optimo 15-40mm is the one if you want a zoom. The housing cost from Gates is really quite reasonable if you compare it to the cost of a good high end fluid head and sticks.

     

    All up .......about 120K! ...oh forgot about the taxes to import all this. Yikes! I'm far happier investing in the lens then the camera. Cameras come and go....a lens is forever.

     

    Now after all the noise i'm considering dropping out of this as well. Not because i've had a change of heart blah blah blah. Where i dive there is a beautiful lodge in the most ideal location that has come on the market. I've had my eye on it for close to 15 years. The owners said they would NEVER sell.......now its come on the market for the first time since it was built 20 years ago. Its a lot of cash for sure but what a place to live!

     

    So cant afford an over the top camera setup AND a lodge. Besides Dragon is on its way :-)

     

    Decisions decisions.........
