Apple's iPhone 16 beta introduces focus and exposure lock feature but faces usability challenges

Apple's latest iPhone 16 beta introduces a half-press feature to lock focus and exposure, similar to traditional cameras. While this addition is welcomed, real-world testing reveals it is still a work in progress. Users find the feature difficult to use due to its sensitivity and the multifunctional nature of the Camera Control button. This can lead to accidental photo captures or losing the focus lock when reframing. Apple may address these issues through firmware updates, potentially adjusting pressure sensitivity or modifying how the feature operates. Improvements could enhance usability and make the feature more effective for photographers.
