The Nauticam GH5 Housing is Here and Shipping!


2017-05-19


The Camera:

The Panasonic GH5 is a new camera body, positioned above the successful GH4, and improving it in every way.  At the core is a 20 megapixel sensor with completely revamped video functionality.  When shooting motion, GH5 reads the entire 5K sensor, then resamples in camera to create each individual 4K frame.  This results in increased sharpness with no change in lens angle of coverage!  Panasonic didn’t stop there, unlocking UHD video capture at up to 29.97 fps with 4:2:2 10-bit chroma sub-sampling.  Simply put, this means the GH5 can capture twice the color information with 64x the precision of a 4:2:0 8-bit system.



The Housing:


An exceptional hybrid housing to complement an exceptional hybrid camera, NA-GH5 is designed from the ground up with both video and still photo shooters in mind.  Incredible engineering, enabling fingertip control access, has made Nauticam famous.


The housing is small, but not at the expense of functionality or ergonomics.  Integrated handles provide a sturdy and comfortable base to operate the system from.  A sculpted shutter release lever, thumb lever for AE-L / AF-L, and well placed control dials provide the same operational feel as any Nauticam DSLR housing.  Control buttons are placed within easy reach of the handles, with sufficient spacing to allow easy operation, even by feel. The NA-GH5 is a professional grade underwater housing, built with cutting edge manufacturing technology, supporting the pro-level GH5 camera body to its full potential.

One, Two, Three, THREE Close-Up Lenses in One !


2016-12-13

The new Saga Trio is three close-up lenses in one.  Some might count it as four lenses in one.




The Saga Trio contains two close-up lenses (diopters) in a sealed unit.  Two easy to use levers allow you to select just the right amount of 'power' you need in just a second or two.  One lever operates a +5 diopter lens, the other operates a +10 diopter lens.  This innovative device allows you instantly to select any one of four combinations of close-up lens strength.



  • 0 power (no close-up lens)

  • +5 diopter

  • +10 diopter

  • +15 diopter.

The New Canon EF 11-24mm f/4L USM Underwater


2015-05-29



The new Canon EF 11-24mm f/4 L USM is an incredible lens, both in terms of wide angle field of view, and in how amazingly well the distortion is controlled at focal lengths this wide.  Canon has seriously upped their lens design game, and some of my favorite optics from any manufacturer (including Zeiss and Leica) are the 24-70 /2.8L II, 100mm /2.8L IS, and 8-15 /4.  Is the 11-24 good enough to make that list?
