I'd like to ask if anyone's aware of the Aquatica housing being backwards compatible with the GH3?  The GH3/4 bodies are by all accounts are the same, except for the taller mode dial on the GH4.  Not sure about clearances inside the housing, but hopefully that wouldn't be a problem?

 

The paperwork says yes, but I would still like to physically try it before going official on this, we designed using the GH4 camera and did not have a GH3, this being said, as you mention, both camera share the same physical property apart from the mode selector dial.

 

I have put this on top of the "to do" list of the engineering department.

Hi Jean,

I already invested in a Zen 8 inch dome with an Aquatica mount, can I use the same for your GH4 housing?

I have the panasonic 7-14 and contemplating to buy the faster 12-35mm 2.8 cause it's faster. Is the above dome good for such lenses?

 

Thani, It should normally fit if the bayonet was designed properly, To be honest I have not put the 12-35mm f/2.8 on the optical bench, typically for this lens I don't foresee any problem, although, I would still recommend the SW8 as a more compact solution (the optical performance are equal to our regular 8'' dome port) and the lens has a much lesser field of view than the 7-14mm.

 

So far in the wide lens range for the Micro 4/3, the Olympus 9-18mm and the Panasonic 8mm fisheye do seem to have the upper hand. in mid range, both the Olympus 12-40mm f/2.8 and the 12-50mm (which has good close up potential) are the favorite. 

 

Let me check deeper on the 12-35mm and see if I can get a lens for the optical bench. then I will report back, honestly, I am not really a big fan of slapping things together just because they fit physically, I like doing my homework and seeing that everything is in the right place optically as well before going official.

I recently compared Nauticam and Aquatica for the EM1 (only on land).

 

I found the Nauticam EM1-housing a slight advantage in regards of reaching the important buttons. However in case of the GH4 housing this could be different.

 

On the other side the Aquatica seems more solid to me, in regards to finish/coating, wheels (less plastic parts)and internal gears for the buttons.

I also find the Aquatica Domes nice - a 4 inch glass dome for the (mmFE) and a nice 8 inch Dome in small size with extensions which you can use with many different wide angel lenses).

 

If there would not have been the long distance between the handle and the Aquatica back wheel I would probably have choosen the Aquatica housing because it feels so solid.

So I think its important to take both in the hand to find out how you can reach the controls which are important to you.

 

 

Paratom, The AGH4 rear control is located differently than on the AE-M1, if you check the press release, there is a side view of the right hand side on which you can see the layout of the control

I'm wondering the same question as well. I like the fact that Aquatica has the powder coating finish, which make it less slippery if I have to hold it one handed. I suspect the Nauticam housing could get scratch easily because of its smooth finish.

 

The Aquatica is also $250 cheaper than the Nauticam version. Of course the big question is what kind of ports is available for the Aquatica.

 

KC_Moses, the ports available for Micro 4/3 series housings are as follow:

 

The 4" Fisheye dome which is, one could say, exclusive for the Panasonic 8mm Fisheye

 

The SW8 which is the same 8'' dome lens we use for our DSLR housing, but with a more compact redesign, so it is more in line with the system original idea of being smaller and lighter.

 

There is an upcoming port adapter that will let you uses current DSLR ports on the Micro 4/3 series housings, that is especially important for the Panasonic 7-14mm which requires a very large dome radius for taking advantage of its huge rectilinear field of view. Shooting over/under shots can be done easily with large ports, so it is quite possible to shoot the AGH-4 using a dome port as large as the 9.25’ Megadome

 

Then, to complete the dome port system and give it more flexibility, there are various extension tubes that can be inserted between the dome ports and housing, these are used for positioning the optical center of the dome and lens as close as possible to each other in order to optimize their optical performance.

 

On the flat port side Aquatica has three ports, that can be used for close up and macro work, again these combined with the existing port extension will give some form of flexibility in regard to lens selection.

 

So if you include the access to the line of DSLR ports, you have a total of 11 different ports to choose from.  

 

Cheers

Dimitris, it looks like a Canon 30D housing, when you push the plate with the rubber wheel, does it spring back? there should be a spring underneath the flat plate to create some pressure on the control of the camera, its possible that it fell, let me know at jean@aquatica.ca, we should be able to get you back in the water with the housing soon.
