Yes, they're cheap. They look and work that way. Had a few occasions on dive boats with co-divers having problems with stuck buttons on their ikelite housings... If you want to save money over the Nauticam housing, I'd go for the Aquatica GH5 housing.  They are build like a tank. Highly recommended. I would have taken one but it came out a bit late for some upcoming trips at that time...

One more vote for Nauticam over Ikelite. I ve used both and the extra money are worthy.

Hi all.
Now that everybody has had a good chance to get some experience with the gh5 i would like to hear if any of you have had to admit that the micro 4/3 sensor is just a bit too small to capture great photos with ambient light below 20 meters?

I don’t think people that buy the GH5 do it to take deep water ambient light besides depending on light you can take pretty decent video at 25 meters without lights

Look on youtube or vimeo
Am not sure the point you are trying ti make here
I have shot at 40 meters with a small sensor compact see Bianca B here

https://youtu.be/JWdwsPdBxqY

You take video typically at 1/50 shutter speed this means on a compact with f/2 you shoot at ISO 800 even at depth
On a mft with log mode your base ISO is 400 and even if you shoot one stop smaller f/4 or even two the camera works fine at ISO 3200

Consider that video has only 6 stops of dynamic range in HD and this is something even a tiny sensor can achieve

Different story if you print or display pictures on a retina 6k screen where clearly you need full frame but for video purpoae although large sensor is of course better for amatorial or semipro the cost is not worth it. Camera 2x price housing 1.5x price compared to GH5

Firstly if you are looking at stills photography I don’t think the GH5 is the right choice. The other cameras have better flash sync speeds, builtin flashes, higher bit depth raw modes and higher Mp etc.

But sensor size and iso performance (I don’t think) is something to consider these days in m43 cameras. I remember thinking ISO800 was a high iso back with my E-1. These days it’s a non issue.

But is the m43 sensor too small for ambient shots? No way.

If anything it’s better, you gain a load of depth of field for free with m43, running the same settings as FF and also don’t have to worry so much about diffraction as you don’t need to run >f16 to get everything in focus.

Below is a single frame (not even a photo!) taken at 27m (f5.6, 30fps, 1/60th)

Nothing wrong (to me) shooting landscape at depth. :-)

I don’t even think this is fair te GH5 is good at stills too the OMD-EM1 mark II maybe has another stop of ISO but the GH5 has 13 stops of dynamic range and plenty color depth to compete with cropped sensor.
A lot of people out there have this as primary rig. Only Pros and people with deep pockets go for full frame and yes there is a difference but for plenty it is still fine
I have a Nikon D7100 a GH5 and am thinking of selling the D7100 because there is not much apart not doing low light photography

Good video, it was good to see the potential of the LX7 in real life.

I understand your confusion, i have not been very clear.
I am out looking to find out what i should buy.
I need minimum 60 fps and 2.7K in video (4K is ofcourse also very good) 10 bit is prefered.
But I also would like to print bigger pictures, jus as you mentioned.
I saw a picture once taken by a Canon 1dx M2 in ambient light and i loved it, but that camera i way out of my pocket.
So gh5 seemed to be a good alternativ.
I am just a bit concerned about its performance in ambient light around 25 meter.

I have also thought about waiting for a possible gh8 or something like that and then maybe buy a temperary camera until then.
Aahh just updated and saw your two answers :-)

Hi Richard

Did you use the 14-42mm and the wwl-1 for that picture?

Best regards
Stefan

If you are really concerned so much about low light conditions there is always the GH5S option ;)

No, no filters. I gave up on filters a while ago.
