There have been many rumors about the iPhone 16 and the possible integration of a Capture button, but the latest information suggests that it could be mechanical.

Despite the fact that Apple 's iPhone 16 isn't expected to be announced until September 2024, rumors haven't stopped circulating. All indications are that there will be a Capture button on at least the iPhone 16 Pro models, although what form it will take is still up for debate.

According to two people familiar with the development of the series, the Capture button is said to be mechanical and has additional functions. It will be touch-sensitive, allowing users to swipe to adjust zoom levels.
Since the Capture button can be pressed, it makes it mechanical, which is different from previous rumors. A mechanical switch that responds to touch could prove interesting, although there may be some difficulties in implementing it.
Such a button would pose problems for case manufacturers. Its touch-sensitive surface would likely be unprotected, and it would also require a lot of space for the half-press function to work.
Apple appears to be testing feature on all iPhone 16 models, but it may not be available on all versions.
