William J. Claff posted the graph above showing the revised Estimate of Sony A9 Photographic Dynamic Range (PDR). It shows that at low ISO the A9 is around 1 stop behind the A7rII but 1.2 stops better than the much more expensive direct competition from Nikon (D5).
Yesterdays Dpreview article created some surreal discussions on the web. If you think cool minded it is obvious the A9 doesn’t have the same A7rII Dynamic range performance. With double the pixels the A7rII is also the class leader in the FF world.
Moreover: The A9 is made for sports photography! And sports cameras are by nature trimmed to perform best at mid ISO settings because they mostly use the camera at fast shutter speed. If you complain about the A9 not having a good performance as the A7rII at ISO 100 it would be like complaining the A7sII has no 50 megapixel :)
What matters is that REAL professional photographers shooting with the Nikon D5 or Canon 1D now can have a camera with much higher dynamic range and speed…the Sony A9!
Some more good news: Jeremy Smith tested the A9 under condition he would typically see banding. And his quick and dirty conclusion is that the A9 has no banding issues (see video below). But I would hold on judgments until we see more because some other tester reported some minimal banding in mixed light conditions.
Focus Numerique tested the A9 noise performance:
You can easily push to 1,600 or even 3,200 ISO without any hesitation and even at 6,400 ISO, the pictures are really impressive.
