In Topic: Fluid video tripod head

20 November 2014 - 04:16 PM

Hi all, thanks for the answers.

 

I do take my video job seriously. For years I've used regular topside tripods (Gitzo) and ball heads underwater. Caring them underwater its not a problem (although I admit that some times a lift bag will be very handy..)

But now, after 15 years of use uw, my Gitzo head (ball head) needs to be replaced. I have disassembled it many times to clean it, and thats why I wonder if that will be possible with a fluid video head and, if not, how long will it last.

 

Many times I've used them in situations where a small / dedicated uw tripod will not work due to its limited size/high. In some very limited situations I've used a monopod, but most of the time, I need a tripod so a head is a must.

TLC tilt/shift head looks good but I'm not sure about the smoothness of the movement. And i don't need the legs. But, anyway, I will look more carefully at this option, especially because of it's corruption free constrution.

ULCS looks too small for the kind of gear I need to put on it (DSLR housing + external monitor + arms and two lights). 

 

Cheers,

Yes, how is this project? I'm very curious too...


In Topic: Subal D7000 Port Boyancy

Are you sure?!?!?!?!

 

I'm not sure if you are making a statment or posing a question, thought.

I use Subal equipment for a long time and (as in any other brand) the underwater weight of the 8" dome vs the 60mm flat port are quite different...

 

Cheers,


In Topic: Thoughts on external vs Internal filter ?

25 September 2014 - 06:24 AM

Red filter can ne benefical to both photo and video in conjunction with custom WB to mantain blue water color and prevent it to become grey/dull.

If you need to use flash/video lights for the foreground (while using the filter) you need to put a cyan filter over the light so subjects will not become redish.


In Topic: 10.5 vs 10/17

25 September 2014 - 06:18 AM

Hi all,

 

The Nikon 10,5 is one of the sharpest fisheye lens in the market, and much sharper then the Tokina 10-17. Many full frame photographers had to stop using the Tokina in high resolution cameras like the Nikon D800 (I know it's a FX lens, but you can use it for circular photos at 10 mm).

Being a fixed lens and a faster then the Tokina (f2.8 vs 3.5-4.5) it's hard to believe that it focus slower.

 

Depth of field of both wide open, will of course be slightly less in the 10,5 since you'll be using f2.8 vs 3.5 in the Tokina.

 

Cheers,
