Clearly his comments are about video really. He never once mentions the lack of an EVF, and his comparison against the A7Cii (all 5 seconds of it) was just "the image quality is nowhere near as good" - which for stills is clearly just nonsense.
Sam is 99% a videographer, so yeah that might definitely be the case.
Although I think it is not made a photo OR video camera, it is a CONTENT CREATOR camera.
I know for many people in this forum these words are like bad language, but that is the proposed target audience, and the biggest reason why so many camera's are still sold.
I presume also that the S5ii(X) is also mainly sold to content creators, I'm one of them, also for me it is definitely mostly video (90%).
I do think I might make more photos now that Lumix Lab is compatible, but we will see in the future.
And remember: R&D is not done in a few months, when the company where I work for develops a new product, we talk often about 2 to 3 years development time. And a few months extra when anything goes wrong according plan.
But I fully agree with Dirk, because of these audiences there is still the amount of R&D money, and this will also be used for more high end camera's in the future...
