Hello,
I've been searching for the sensor size, pixel pitch, and other related specs of my iphone 11's main camera for a long while. I've stumbled upon many places that gave inconsistent values, and are hoping to get some clarity on some terms.
From this site https://capturetheatlas.com/camera-sensor-size/, they said the sensor size is 6.17x4.55mm. Diag: 7.666mm.
While in this post https://www.reddit.com/r/cinematography/comments/dadfas/gate_dimensions_of_individual_iphone_11_pro/, the OP found 5.88x4.42mm from EXIFdata. The primary camera should be the same on both the Pro and normal. So the Diag:7.356mm.
And if I'm understanding the following statement correctly from https://www.dxomark.com/apple-iphone-11-camera-review/, "Primary: 12MP 1/2.55-inch sensor with 1.4µm pixels and 26mm f/1.8-aperture lens", then the diagonal of the sensor size is 1/2.55-inches or 9.906mm.
So yeah as one can see, there's a lot of confusing info out there, and I'm not sure what to trust. But I wish to at least get some clarifications for now. Please let me know if I have the following terms correctly understood?
12MP refers to total # of pixels on the camera sensor
1/2.55-inch refers to the diagonal length of the camera sensor
1.4µm pixels refers to the pixel pitch or dot pitch
26mm is the focal length in 35mm equivalent
f/1.8-aperture lens refers to the size of the aperture
