In Topic: NEX 5 wide angle lens adapters for Nauticam. Which one?

18 March 2011 - 10:36 AM

One other thing to consider between these two add-on lenses is if you are shooting with one strobe you have a chance to light the frame using the rectilinear lens (100 degree diagonal FOV). The fisheye would be tough to light even with two strobes. For available light shooting, I'd go with the fisheye, you can de-fish it later if you want to in software. Personally I'm going for both, a $120 add on lens doesn't seem so steep when we just dropped about two and a half grand on the case and ports!

Quick calculation of FOV:

Fisheye (15mm)
HFOV 147
VFOV 94
DFOV 184


Rectilinear (18mm)
HFOV 90
VFOV 67
DFOV 100

In Topic: Aquatica AN-5 macro option?

Aquatica does list a dome extension on the website. http://www.aquatica....s_dslr_an5.html


I believe that extension is intended (and required) for the fisheye adapter in the dome port. Interesting point though, in theory you could stack several of these and then the flat port to make a macro port. By my math it would take 4 of those 16.45mm extensions to house the 18-55mm zoom. I'm not sure how stable/secure this would be though with all those interfaces?

That Acquapazza looks pretty nice. I like the angled viewfinder. I'm a no-touch diver and sometimes I'm guessing on the framing with my current setup if I want to get blue water in with the subject. Do you know of a USA distributor/reseller? From what I can tell it's about 50% more expensive than the Nauticam, but I'll definitely consider it.

Regarding Sony alpha macro lenses using adapters, I don't think those will fit in the Aquatica case unless there is a port extension for the pancake port I'm not aware of?

In Topic: Red Filter + Blue Diffuser?

when I don't quite hit the high spots...


Yeah, I completely agreee with the logic. I guess I'm on the border of "serious" photographer and vaction shooter. I only get in 20 or 30 dives a year and I hate it when I don't have the right lens to capture the momement when that manta ray flies by or I spot a cool pygmy seahorse. On the other hand, I do frame some of my better shots and I'm pretty proud of some that are hanging by request in other people's houses. So I'm still trying to create that "magic" camera that can:

  • Have good ISO 400+ quality
  • Filter blue light on demand
  • Macro on demand
  • Wide angle on demand
Maybe I should look at this as a business opportunity :)

In Topic: wet stackable teleconverter?

Yeah, I messed up the mental image, a diverging lens in front would have the opposite effect making it more wide. Oh well, I'll just have to savor my "macro dives" until someone comes up with a wet primary lens.....
