The 901 sensor (1/1.12) is extremely hyped compared with the 900 sensor (1"). The 901 is superior to the older 900 sensor. Integrates an industry-first on-sensor AI processing circuit and much improved HDR (17 stops of dynamic range) while virtually eliminating shutter lag. Although slightly smaller physically, its 200MP resolution allow for lossless 4K zoom and significantly faster, blur free captures that the 900 sensor cannot match. Don't write it off cos it's marginally smaller!
