In a teardown video posted on Reddit (https://www.reddit.com/r/apple/comments/g6w8ag/teardown_of_the_iphone_se_and_comparison_with_the/) the author claims that while many parts are shared between the iPhone 8 and SE the camera appeared to be different. However, from the video it was unclear what type of sensor was used on the camera (they still might be the same).
PS: The front camera seemed to be the same as on the iPhone 8.
