In Topic: Who is excited about Blackmagic Pocket Cinema 4K?

14 April 2018 - 12:45 PM

All Red 4 to 8k cameras are fan cooled as a necessity due the heat that is generated by the processors when shooting 4k, but that has not stopped the pros from using them underwater. Plus, aluminum housing work as a bit of a heat sink in dissipating the heat generated by the camera. 


Seeing the Black Magic camera being fan cooled as well should be a good thing for a camera like this to handle longer run times and consecutive shooting than non fan cooled 4k cameras. The one downside, considering that it is hard to have a camera fan cooled and weather sealed at the same time, with a fan cooled system just a few drops in the right place could spell serious trouble.

In Topic: Nauticam D500/Tokina 10-17 FE Port Discussion

With the Nauticam N120 140mm dome (which I use now) you will need to add the 10mm extension ring to get the best out of that port/lens setup. With the Zen 170 (replaced it with the Nauticam 180mm) the 20mm extension ring will be needed there.

Since I am also coming from the DX (Nikon D500) shooting camp, I am curious if the WCAP will work with the Nikon AF-S NIKKOR 18-35mm f/3.5-4.5G ED Lens. The lens features a comparable 35mm focal length equivalent of a 27 - 52.5 mm on DX format camera.


Physical dimensions of the lens run approx. 3.27” in diameter x 3.74" long (83 x 95 mm), which do not change when the zoom is racked out to 35mm like it does with the Nikon’s 18-55mm f/3.5-5.6G. The lens takes a 77mm filter, but I don’t quite understand what the issue is there where Ryan Canon mentioned it his post. 



In Topic: Help for lense choise for canon eos 7d mark II

12 February 2018 - 11:40 AM

Before switching back over to Nikon (D500), I shot extensively underwater with both the Canon 7D and 7DmkII. The must have lenses is the Tokina 10-17 fisheye for wide angle which can be used even with a 100mm mini dome port and the Canon 60mm macro. If your aim is really small subjects from pygmy seahorses to hairy shrimps, than with the Canon 100mm or Tamron 90mm macro. 

In Topic: air travel with strobes (air pressure effects)

07 February 2018 - 10:44 AM

I all the years (36+) of air travel, with the highest amount during the 1990’s where I was traveling as often as twice amount for magazines, I never gave a second thought high altitude pressure changes might have on my strobes in the belly of a passenger jet. And I have traveled with a few, Subsea, Oceanic’s, Ikelite’s, Sea&Sea’s, MCD’s, etc. and never have had appear to a affected buy the journey. As for batteries, especially my Seas & Sea’s, my only trouble there was not have airport security on occasion not understanding what they were, to more recently convincing them that they are NiMh and not Lithium.
