Apple’s latest top iPhone has difficulty focusing near objects. The manufacturer has smashed itself in a developer press station for WWDC 2021. So far, it was unclear where this so-called Minimum Focus Distance (MFD) was with Apple smartphones; The Group had not specified her in the technical documentation.
More distance is better
While the wide-angle camera of the iPhone X still creates down to 10 cm distance the autofocus properly carried out correctly, it is only 15 cm at the iPhone 12 Pro Max due to the integrated sensor shift optics for image stabilization. The iPhone XS Max and the iPhone 12 Pro remains 12 cm. When using the telephoto lens, it is 40 cm for iPhone X, XS Max and 12 Pro, at 12 Pro Max, however, 50 cm. All this goes out of the "What is new in the Camera Capture area?"-Video that the Group has published in the past week.
The higher MFD at the iPhone 12 Pro Max has concrete effects on the use. So it can be difficult to focus on objects, which every user has already determined. Apple calls about the abscan of relatively small QR codes, where the user must approach with the camera – the focus will fail here if necessary. Bypass this is done by increasing the distance and zooming handically on the object to be detected.
API helps – but developers must have ran
In iOS 15 there is a solution that can sometimes automate this process; However, developers will have to implement them handically. You can calculate over several new API functions, how much distance must be available for an object in the search is completely recorded and the user (AN) guides (AN) or the zooming stage predicts, which motivates it to engraving the distance.
The new procedure should implement such developers who regularly cancel QR codes in their apps; But even for alternatives for the camera app such functions are very useful. The knowledge of the minimal Focus Distance helps the latter helps to make various other features suitable in your apps – why Apple only indicates the values now remains unclear.
