Niccolò Fabi – Meno Per Meno Tour 2023 – Live@Teatro Massimo, Pescara
Covering Niccolò Fabi’s concert for Rockol, gave me the opportunity to test an X-T4 with an XF 150-600. The image quality is on a par with the X-T3. This was to be expected. However, I have some reservations about the autofocus. The lens also needs to be examined in more detail before I can form an informed opinion.
