Sony has updated its sensor page and shared the details of a number of new image sensors it's made. Sure enough, a few of them bear a striking resemblance to sensors inside other manufacturers cameras.

One sensor in particular, a 26-megapixel backside-illuminated (BSI) APS-C chip with product code IMX571, bears an uncanny resemblance to the sensor used inside Fujifilm's X-T3 camera. While Fujifilm hasn't confirmed it's a Sony sensor inside the X-T3, General Manager of Fujifilm UK, Theo Georgiades, did say it wasn't a Samsung sensor used inside the camera, as some believed to be the case, leaving little doubt that it was Sony who manufactured the sensor. The specs listed under this image sensor on Sony's website all but confirm that speculation.

It's also worth noting that there's a good chance we'll see Sony build something around this sensor as well. The a6300 and a6500 both almost certainly use the same sensor as Fujifilm's X-T2, so it's not a stretch to imagine Sony will be releasing one or two A6000-series cameras using the 26-megapixel BSI image sensor found inside the X-T3.

The BSI IMX461 sensor has been in the works for a long time and based on Fujifilm's announcement that it is currently developing a 100-megapixel medium format camera, it's likely this is the sensor that will be inside of it. The sensor has 3.76 micron pixels and features a maximum frame-rate of up to six frames per second.

The IMX299 is a bit harder to hit on the head, but based on it being 11-megapixls, having 4.63 micron pixels, and a 60 frames per second readout, it's almost certainly the sensor found inside the Panasonic GH5S.

Last but not least is the IMX272. This 20-megapixel Four Thirds-type sensor has 3.3 micron pixels and a maximum readout of 60 frames per second. This has been confirmed by TechInsights to be sensor inside the Panasonic GH5.
