This week I have been in contact with Nauticam that have given me some final details with regards to the NA-LX100 housing that will be released in the next weeks and is already available for pre-order in Hong Kong.
The housing is confirmed to have a changeable port system the default is the rectangular flat port as in the image below.
When shooting 4K the Panasonic LX100 focal length is 26-81mm which means that in water the default port will give a range of 35-108mm due to water magnification. This is however negated by the increased working distance so don’t get too excited about macro.
There will be a flip diopter for the rectangular port as a separate accessory. Due to the limited zoom of the LX100 a strong diopter with power of at least +10 in water is required for macro.
The other option displayed was a mini dome port.
Nauticam has confirmed that this dome is 3.5″ wide and unfortunately there is no provision currently for a flip diopter for this port.
The 3.5″ acrylic port is probably the most versatile option for the Panasonic LX100 and I am a bit puzzled of why the flat port is offered as a default. The mini dome seems perfect for all round reef use when there are no really small critters and medium size fish.
Nauticam has also a super wide option that utilizes a short port with a 67mm thread. This takes the Inon UWL-H100 from what we have heard and also a new lens Nauticam has designed.
The zoom will be locked so the lens will stay at 24mm
limited to circa 50mm which means with the wet lens this is a 16-32mm wide lens in water, I am not sure however that zoom in will be a possibility with the Inon lens but will be possible with the Nauticam lens as far as I understand.

So what is the strategy for Nauticam and this housing?
It is quite clear for me that the Panasonic LX100 has the same 4K capabilities of the GH4 the same IPB codec and processor. It falls short of cinema options but costs half of the GH4 body.
So for your perusal those are the equivalent options
Panasonic LX100 $899 NA-LX100 with Short Port and Wet lens $1,700 circa
Panasonic GH4 with 7-14mm and 6″ dome $2750 housing and port only plus camera and lens $2,399
The max field of view of the two options is almost the same however you can’t zoom the LX100 due to the zoom lock on the housing.
Price Difference $2,550
Panasonic LX100 $899 with 3.5″ dome circa $1,300
Panasonic GH4 with 12-35mm and 6″ dome $2750 housing and port Camera and Lens $2,399
The LX100 is wider in 4K at 26-81mm vs 28-81mm of the GH4
Price Difference $2,950
Panasonic LX100 with rectangular port $2,000
Panasonic GH4 with 14-42 and 35 macro port $1,815 housing and port $2,540
The GH4 will have more magnification due to the longer focal length with the same diopter.
Price Difference $2,355
So the performance may be better but the price difference is very high.
The total cost of the Panasonic GH4 plus lenses housing and port is around $6,640 but the LX100 stops at a much more modest $2,400 without the wet wide angle lens. This still does not include flip diopters adapters and lens worth another $800+ but gives an idea that the total will be around $3,200 for the whole set.
You can get a complete 4K underwater video rig around $4,500-4,700 including tray, video lights and all the rest which few years ago would have been unthinkable.
