We already received some PDR results from Photons on Photos, which you can check out here, but now DPR is getting into sensor testing and you can check out here or read the excerpts from it below:
The Sony Alpha 1’s dynamic range isn’t just good for a sports camera, though. It’s nearly a match for the very best full-frame cameras we’ve tested, despite the fast sensor scan rates that enable so many of its headline-grabbing capabilities…Compared to ‘pro’ offerings from Canon and Nikon, the a1 shows significantly more detail and less noise, with the 1D X III competing on noise levels due only to noise reduction that reduces detail.
The sensor in the Sony a1 displays a marked improvement over the first-generation full-frame stacked CMOS seen in the a9 and a9 II, with increases in resolution, readout speed and dynamic range. Up until now it had seemed as though fast sensor readout and high dynamic range were mutually exclusive. The a1 has the fastest sensor scan rate of any camera we’ve measured, to our knowledge only roughly 1ms or ~25% slower than a traditional mechanical shutter.
