Hey /r/iPhoneography,
I took the time to sift through EXIF data from the iPhone 11 Pro and compile some sensor measurements that I thought were interesting from a filmmaker’s perspective. I'll list out the data here, which includes comparisons to established motion picture film formats, and then add thoughts below:
Ultra-Wide
- 1.54mm f2.4 Lens
- 3.96x2.97mm (Photo gate)
- 3.77x2.12mm (Video gate)
Wide
- 4.25mm f1.8 Lens
- 5.88x4.42mm (Photo gate)
- 5.60x3.15mm (Video gate)
"Telephoto"
- 6.00mm f2.0 Lens
- 4.15x3.11mm (Photo gate)
- 3.95x2.22mm (Video gate)
Selfie
- 2.71mm f2.2 Lens
- 4.24x3.18mm (Photo gate)
- 4.04x2.27mm (Video gate)
Super8 Crop Factor Comparison (5.70x4.20mm gate)
- UW = 1.50x
- W = 1.02x
- T = 1.44x
- S = 1.41x
Super16 Crop Factor Comparison (12.52x7.41mm gate)
- UW = 3.32x
- W = 2.24x
- T = 3.17x
- S = 3.10x
Super35 Crop Factor Comparison (24.92x18.67mm gate)
- UW = 6.61x
- W = 4.45x
- T = 6.31x
- S = 6.17x
A few things are worth mentioning here, the first of which is that these measurements are only accurate if you disable electronic image stabilization for video recording. While I couldn't find any hard data on how much resolution is lost when the iPhone turns EIS on, I've heard that it uses a roughly 3.6K extraction from the sensor. Second, the rumour is that the ultra-wide sensor is performing quite a bit of extra processing to combat distortion from the extremely short lens, which would explain why it uses a smaller extraction than the "telephoto" sensor. The ultra-wide sensor is also unable to shoot raw photos in still mode. Lastly, it's really interesting to see how much bigger the wide sensor is than the other three; so much so that it's basically equivalent to shooting on Super8.
