MFT new system for Panasonic GH4

My friend has bought a Panasonic GH4 and is now searching for the best underwater housing system.

Which would that be?

Nauticam?

Subal? Subal has not really a great port choice for different lenses or does somebody have better informations (Olympus 60mm, Olympus 8mm 1,8, Olympus 12-50mm)

Thanks in advance for good tips!

Kind regards

Armin

Does the Subal unit come with an integrated vacuum sensor & zinc anodes? At recent Nauticam housings these belong to the standard setup. Otherwise true, Nauticam has great port availability, however, I would also consider using a flat port and a WWL-1 for wide, and a close-up for macro.

For workmanship they are probably equally good.

OTOH, Subal is made in Austria, your factory support is on your doorstep, which can be a great advantage:)
