For the 12ProMax this seems a physical limitation of the new lens system, resulting in an inability to focus inside of ~4 5/8”. No mention was made by Apple of this change, and all the “professional” camera writers/reviewers/bloggers were so mesmerized testing night mode that they failed to even notice this.
This means the min field of view is much larger, and as a result the effective macro resolution,and thus capability, is crippled vs past models.
And so, to summarize my own tests in simple terms:
\\
The iphone 12 pro max’s ability to take detailed close range photos is over 40% worse than last year’s 11 pro max. ‘’
All other 12’s including the 12 pro do not have this limitation. They can focus at just under 3” , in line w previous years’ models. There was a Camera software bug in 14.1 that made it extremely difficult to focus at that distance on the 12 pro, but that was largely was addressed in 14.2.
