A well done job in DR, AE/AF accuracy improvement and speedy speed. I like to see sony to keep a big smile for all new generation models. Btw, where is A9R while we speak
PDR from Bill's works: A7R -> A7R2 -> A7R3 -> D850

Does this pretty much confirm that highlight DR isn't measured in these tests? ISO 50 (Sonys) and 32 (D850) aren't native, so they just take the base ISO (Sony at 100, Nikon at 64), overexpose it by 1 stop, then pull it back to the proper exposure in RAW/JPG. This would lose 1 stop of highlights by clipping it. Yet the DR scores actually go up, despite losing DR. Of course, on the shadow side, it would feed the sensor even more light for cleaner shadows.
That said, from testing sample RAWs, the A7R III has about 0.25 stop advantage at highlight recovery over the D850. A bit odd, since my A6300s and old A6000 have another 0.20 stop of highlights on top of that. Then again, adding highlight DR would bring Bill Claff's score up to around 14 stops...
