This Sony IMX903 should theoretically give you better than a 1/1" sensor bc of the new stacked sensor technology. Sony has moved the transistors sitting next to the pixels to underneath the pixels on their own layer. This allows for larger pixels possibly even doubling the light gathering capability without increasing the size of the sensor itself.Come on Apple just give it a 1/1" sensor already..
The OnePlus 12 just launched and is the first one using this stacked technology. They are using the LYT803 which is slightly smaller at 1.4" than the IMX903 at 1.14" going in iPhone 16 (hopefully) but the photos are really good.
For comparison the OPO X7 is using Sony's latest and largest non-stacked sensor, LYT909 - a 0.98" sensor. I personally think the overall quality is better on the OnePlus than the X7. Obviously software is a major factor here but you can see the comparisons on YouTube.
I'm really excited to see what Apple can do with this latest sensor from Sony.
