I remember that about ten years ago, an Italian computer magazine did a kind of investigation on the price difference of various electronic devices between the US, Europe and Asia. They wanted to find out whether the price differences (which were more significant then than now) were due to factors such as logistics, taxes, duties, production costs, etc. In the end, they found no repeatable pattern among the various electronic appliances analysed and concluded that it all depended on how much that market was willing to pay for that item. Perhaps the Nikon and Panasonic marketing departments simply have different views or different data on their customers. And I think the customers of the brand are completely different. I have Panasonic air conditioners at home, my mother a microwave oven. Nikon is an exclusively photographic brand. By the way, in Italy Nikon and Panasonic have official technical service provided by the same company.

The problem with Seafrogs are the low quality domes and ports. P.S. I have a housing for the GH4 that I use as a paperweight 🙂

Until the early years of digital cameras, the few housing manufacturers produced housings for one or at most two camera models. The top of the line for Nikon and Canon. Then digital cameras became more and more complicated, with more and more controls, and the manufacturers went into crisis. the digital revolution caught them off guard and they could not keep up with the new releases. It took over a year to design and make a housing. Nauticam revolutionized the market by applying industrial design and construction logic to an industry where all companies were (are) little more than skilled craftsmen. Now the housings come out almost simultaneously with the release of the new cameras, probably thanks to agreements between companies that are able to get the designs in advance. They are producing housings for the more niche camera models, the problem is that the cost has skyrocketed. A housing for a mirrorless goes from 3K Euros to over 4.5K Euros (without dome and lens port) A housing for a cinema camera goes to over 20K Euros with all the accessories. The second hand market is ruthless with prices less than 50% if you are lucky to get one of the latest, mainstream models. When you decide to change, the camera body is almost the least of the problems.

Well, yes and no. It depends... Modern housings bring outside all the controls and remap them in a more ergonomic position for underwater use. A housing is like a glove with a perfect fit. Once upon a time the internal mechanisms allowed micro adjustments to compensate for small production variations between camera bodies. They no longer exist but I remember that the legendary GH2 was little more than a toy and when I changed the camera body because I had flooded the housing I had to change the rubber wheels that acted on the diaphragms because the wheels of the two bodies were slightly different. Now with more professional cameras the problem no longer exists. To show you how even 1 mm can make a difference, this is the back of an S1H, outside and inside. A small gem of engineering. You understand that when a new camera model uses the previous body, I open a bottle of sparkling wine 🙂

Actually from Panasonic website the two cameras seems identical on the external dimension at least. 100,3mm x 138,4mm x 99,6mm Gh7 is 805 g vs 823 g of GH6. Then on site Camera Decision I found this photo with 1mm of difference.

Guys could you point me to an official statement that the GH7 body/controls are identical to GH6? I found a bargain GH6 underwater housing but before I pull the trigger I have to be sure.

Gentlemen, I think we can all agree that at least the FF aesthetic exists and it is all shallow DOF. Youtube told me so!

My Pana 8-18 on GH5 in 4K become 16-36mm I thought the extra raw crop would add to the normal 2x crop. These crops don't fit in my head 🙂

For narrative shots I use a lot the 12-35mm in a 6" dome port. For ambient wide angle shots I use the 7-14mm or 8-18mm on the wide end. Rule #1 underwater is to reduce water/distance. The most useful combo is the (vintage) Pana 14-42mm with a special wet lens which converts the lens FOV from 75°-29° to 130°-50° and it focus basically on the lens. With this extra crop everything becomes too narrow.

So my 8-18m @ 8mm become 22.3mm. Hummm this is a deal breaker for wide angle underwater use...

And for sure he could write anything in the video description...

No but I don't criticize it. I think it is impossible to judge cameras by videos. This is a bias that was born on social media and will never die. I have never heard about a film that it would have come out differently if they had used one camera or another and yet this BS on social never dies. The videos say more about the skill of the author than the camera. I would like to see Roger Deakins with a GH2.... 😉

Guys forgive me for insisting on this raw thing. Tell me where I am wrong. I am here to learn. In M43 I have a crop of about 2x due to the ratio of the FF sensor to the M43 sensor. When I shoot in Prores or H265, the camera uses the whole horizontal part of the sensor and then scales the image to C4K or UHD resolution. When I shoot in Raw the camera uses exactly the pixels needed to get the desired resolution otherwise it would not be raw. I did not understand if in the two options the camera changes the crop factor of the lens. Thank you in advance

I liked but what's in there can't be obtained with the GH5? I see a nice but pretty heavy color grading.

Out of curiosity, I was reading this on ARRI website: https://www.arri.com/en/learn-help/learn-help-camera-system/image-science/log-c I'm newbie about RAW. Does it mean that LogC3 from GH7 not being ARRIRAW cannot take advantage of the mentioned workflow?

This is the GU GH7 review opening statements 😑

I'm reading this in a hurry... What does it means? In 4K prores raw i will have an extra 1.4 crop after the 2x crop of M43?

I had them since GH2 but now I'm thinking to switch to another Brand.

I use my GH5MKII exclusively underwater. I will buy the GH7 hoping to find a GH6 housing on the used market. Saving 4K€... https://www.nauticam.com/products/na-gh6-housing-for-panasonic-lumix-gh6-camera

Panasonic proved to have the best body and thermal design in the market. Just remember that Gh4 (unlimited 4K had the same GH3 body (1080p). And we are still getting Sony cameras that heats like an oven... Gh7 appears to have exactly the same GH6 body that is good to me.

That is the GU special edition...
