Das ist ein bekanntes Problem, siehe auch hier: https://www.fredmiranda.com/forum/topic/1452716/
Note that the default setting F32 for a 135mm lens switches the Techart PRO into Manual Focus mode. There seems to be general agreement amongst FM members that this was a poor choice by the Techart engineers. Firstly, because alternating between AF and MF is best achieved by setting a Custom Button on the camera for AF/MF Toggle. Secondly, because AF is just as desirable for 135mm lenses as for other focal lengths. However, this default setting for the 135mm focal length can be modified via the LM-EA7-CONFIG app.
