Is the sensor itself any different? I care about image quality, not shutter speed. I think most people are the same. The shutter speed is already very fast.The 48MP main camera on the new Pro models comes with a second-gen quad-pixel sensor that eliminates any shutter lag (time between tapping the shutter button and the photo getting snapped) while shooting 48MP images. This is true both when you are shooting at the more storage-efficient HEIF format, and when shooting in Apple ProRAW. You can have your opinion about the upgrade but facts are facts. Get it right.
