Nauticam NA-LX100 Released

On Christmas day Nauticam has released the NA-LX100 housing for the Panasonic DMC-LX100. It is priced at ¥168,000 which is 50,000 more expensive than the last NA-RX100 III.

If this translates correctly in $ and UK prices it means $1,399 plus tax or £895 including VAT for UK.

Prices for the short port for wet lenses and the dome port have not yet been announced but we know that the dome can use the camera at full zoom and that the short port. The US price of the flip diopter for the rectangular port is known and is $220.

Which means we can now update the GH4 comparisons for 4K

Super Wide

Panasonic LX100  $899 NA-LX100 with Short Port and Wet lens $2,000 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.

LX100 $2,899

GH4 $5,149

Price Difference $2,250

Mid range

Panasonic LX100 $899 with 3.5″ dome circa $1,699

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

Panasonic LX100 with NA-LX100 rectangular port $2,299

Panasonic GH4 with 14-42 and 35 macro port $1,815 housing and port $2,680

The GH4 will have more magnification due to the longer focal length with the same diopter.

LX100 $2,299

GH4 $4,495

Price Difference $2,195

The gap is still significant even with the price increase ranging between $2200 and $2500.

There is still an option to use the GH4 with wet lenses although this has only been tried with diopters to date it is technically possible to use a wet wide angle lens.

Panasonic DMC-LX100 Nauticam 4K Underwater video becomes affordable

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 LX100 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

Super Wide

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.

The GH4 will have more magnification due to the longer focal length with the same diopter.

LX100 $2,000

GH4 $4,355

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.

Panasonic DMC-LX100 More Info and Reviews

Like the LX7 the LX100 has a multi aspect sensor. This means that the diagonal field of view does not change in the various aspect ratios.

The camera is a micro 4:3 so the sensor size is half of a full frame sensor at 18×13.5 mm. However only part of this is used by the camera more specifically 13.7×10.3mm are actually used in the same aspect ratio.

Resolution 4112×3088 in 4″3 format

When the aspect ratio changes to 16:9 although the diagonal field of view remains the same the horizontal pixel count increases

Pixel count at 16:9 Aspect Ratio

Now we have 4480 horizontal pixels and 2520 vertical so the horizontal field of view is wider than in the 4:3 or 3:2 aspect ratios.

This means that at normal 1080p the camera will perform like a normal 3:2 sensor at 22.9mm. All of this to say that the LX100 like the LX7 are wider in movie mode than the Sony RX100 Mark III despite the lens is declared at 24mm in both cases as when we go to 16:9 the Sony crops the sensor and goes to 25mm whilst the Panasonic cameras stay at 24mm. So even at 4K 16:9 the LX100 will be marginally worse than the RX100 Mark III at 26mm vs 25mm. Note that the crop is 2.56x at 4:3, 2.47x at 3:2 and 2.38x at 16:9.

We don’t have details about wet lenses yet but for the solution with a dome like the Ikelite housing or the Nauticam mini dome we are talking about a maximum field of view of 79.52º at 4K which is acceptable for most cases.

The challenge like with the Sony RX100 Mark III is at telephoto end were 81mm in 4K is quite little. Panasonic has however the option of the iZoom that was pretty useful with the LX7 and that crops down to a ‘normal’ 1920×1080 which promises to be pretty good with a 2x digital zoom with scaling.

In DxoMark sensor test the LX100 scored the same of the RX100 Mark II and III with a minimal improvement in low ISO.

Which in shorts leaves to the conclusion that unless you need 4K the Panasonic LX100 is not going to be your wonderful underwater camera however if you can process the 100 mbps IPB files that the camera produces, the result when scaled down to 1080p has got so much more quality compared to other 1080p cameras.

The lack of the ND filter compared to the previous LX7 is a miss, but Panasonic though that at f/16 there are anyway the 3 stops so performance will not suffer, we disagree with that as surely diffraction will be substantial at f/16 and we rather have less depth of field near the surface than more.

Let’s face it, the LX100 is half the cost of the GH4 if you use the nauticam housing and this is before the GH4 has added lenses and ports, the GH4 will give you richer color and probably 2/3 step ISO improvement and much more if you use an external recorder but the LX100 is the 4K camera for the consumer and we are looking forward to a full operational housing from Nauticam, Recsea or any other!

 

 

Panasonic DMC-LX100 Ikelite Housing

The American manufacturer is the first to reach the market with a polycarbonate housing for the Panasonic LX100.

Specifications

  • 200 ft (60m) depth rating
  • Controls for all camera functions except Diopter Adjustment Dial, Aspect Selector Switch, Front Control Ring, and Focus Selector Switch
  • Ikelite 5-pin bulkhead with TTL circuitry
  • Near neutral buoyancy in fresh water
  • Weight 4.7 lb (2.1 kg)
  • Dimensions 7 x 6 x 6 in (18 x 15 x 15 cm) including projections
  • 3.9-inch (99 mm) diameter glass lens port

The first thing that we notice is that not all controls are accessible, is this going to be an issue?

Diopter Adjustment Dial – this is normally set fixed

Aspect Selector Switch – this does not change during the dive

Front Control Ring – this controls manual focus and is important

Focus Selector Switch – this switches between macro and normal focus mode an is important if you don’t use a close up lens

As the LX100 with a 24mm lens is not going to be really a photographer dream Ikelite could have spared an expensive TTL converter but I requested confirmation from the manufacturer and they said only a TTL version is planned – not good for us!

The housing looks a bit bulky as usual but considering that for video we access a limited set of controls this is not going to be a major problem except maybe the rear metal buttons.

Probably the best feature of this housing are the accessories.

The housing comes with a large 3.9″ flat round port that per-se is not good for much, however you can add the WD-4 Dome and the macro M67 adapter to improve matters. The WD-4 dome is a glass removable dome that is sharp and will restore the lens field of view and allow for some zooming, the macro adapter allows to mount M67 close up lenses as a push on.

Probably the feature that will miss the most is the focus mode switch as the rest can work quite nicely with focus lock.

Cost wide the housing is $750 with the WD-4 and the Macro adapter this totals at $1115 plus taxes.

The nauticam housing is rumored to be $1,100 without ports so this ikelite housing could be competitive and we like the port system a lot for simplicity even if the choices are a bit limited as all in all this is good enough for video if combined with a selection of diopters. The lack of the focus mode switch could create some challenges in portrait work with the bare port but a series of mid range close up lenses can fix the issue.
