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 ?

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

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,
