Is adding a telephoto camera worth downgrading the rest?
Specifically, Google is expected to use an 11 MP Samsung 3J1 sensor for the telephoto camera, which is the same one that comes with the Pixel 9 Pro Fold. This should improve zoom quality, as the phone will no longer rely solely on digital cropping.
But finding the space to squeeze in an extra camera might be proving difficult for Google, according to the report. The manufacturer is said to have picked smaller sensors for the main and ultra-wide cameras on the Pixel 10, presumably to make space for the new telephoto.
The new image sensor for the primary camera is stated to be a 50 MP Samsung GN8 (replacing the 50 MP Samsung GNV), while the ultra-wide could come with the 13 MP Sony IMX712m which would be a major downgrade from the 48 MP Sony IMX858 it would be replacing.
If those image sensors sound familiar, that’s because they are the same ones used in the Pixel 9a — Google’s current mid-range model. Even the front camera may be downgraded, switching from a 13 MP Sony sensor to an 11 MP Samsung 3J1, matching the telephoto.
Is the Pixel 10 going to take worse photos?

So, for now, we don’t have a good reason to believe the Pixel 10 will take worse photos than the Pixel 9. In fact, it could offer a better camera experience thanks to a more versatile camera setup.
