Photons to Photos Preliminary dynamic range results have been released and they are certainly disappointing for Sony fans if you’re not familiar with the site, which always skews conservatively. You can expect the Sony a7RIII to perform slightly better when final results are available, but it’s unlikely it will surpass the GFX, which makes me wonder where Sony gets their 15 stops of dynamic range measurement from. It’s very interesting that Sony’s claimed dynamic range improvements are not showing up in initial testing. You can manipulate the results here.
Even if there isn’t a jump in dynamic range the Sony a7RIII has a technological advantage over its predecessor. With Sony a9 like performance, it’s very easy to get sharp photos even if you’re new to the system. Many enjoy owning a camera that selectively tracks the human eye so accurately with good image stabilization and Sony is only getting better at this task, while cameras like the GFX only offer the feature as a novelty. Of course, we would get better results and coverage if the bloggers that got access to these events actually owned the cameras they were writing about.
