The sensor in the a1 proves that fast scan rates and high dynamic range need not be mutually exclusive.
You couldn't have your cake and eat it too. Put more simply, you apparently couldn't have your cake and eat it too. It seemed that you could only have high dynamic range and modest readout / shooting speeds, or high-speed sensors with accompanying noise penalties. high dynamic range) of Sony's own a7 III, while Canon's 1D X III only competed with noise reduction that significantly decreases detail. Our dynamic range tests showed that neither the a9 nor the a9 II achieved the noise-free shadows (i.e. While the a9 II improved matters significantly, noise levels in deep shadows were never as low as those of Sony Semiconductor's benchmark sensors. It appeared the a9 traded off dynamic range - by dropping readout bit-depth we surmised - to achieve high read speeds ( nearly 1/160s according to Jim Kasson). low noise) and had gotten used to exploiting this in our photography. We say 'unexpected' because we've grown accustomed to cameras using Sony Semiconductor's sensors offering high dynamic range (i.e. With the launch of the a9, we found a slightly unexpected decrease in dynamic range. With our in-depth review ongoing, we wanted to take a look at whether these sensor capabilities came at the cost of other imaging attributes of the a1's sensor particularly, its dynamic range capabilities. This silent electronic shutter underpins the camera's 20 and 30 frames-per-second (fps) burst modes. It's the second chip of its type following the one in the a9, and with it comes improved readout speeds on the order of 5ms or faster, enabling flash sync speeds of 1/200s with electronic shutter as well as decreased rolling shutter and risk of banding under artificial light, and focus and exposure calculations at 120 times per second. The Sony Alpha 1 introduces the next generation of full-frame stacked CMOS from Sony Semiconductor.
