in a situation when DxO does not receive access to a camera before any retail customers it is perfectly normal for you to expect it to be supported a while after it is available for purchase or rent … you do not like this ?take your beef to Panasonic that they must provide cameras to DxO for free to do the work like the do for Adobe
I have wondered if the splitting away of DxOMark in 2017 reduced DxOLab’s testing capacity.
It would not surprise me if there had been some impact due to sharing (any or all of) staff, testing equipment, test results and access to new cameras & lenses.
The Panasonic G9 II will be supported in December as per this entry from DXOs body/lens support database. Is this not the same as the Lumix G9 II?
One reason for support delays is the number of bodies available for testing in Europe versus the number of reviewers, testers, and software publishers wanting to get their hands on one of them. In all probability larger companies, like Adobe, have priority when getting one of those copies.
Generally, it takes two to three months from the time a camera is released until DxO supports it. Sometimes support is sooner, and sometimes, depending on camera availability, it may take much longer.
