Ciao Patric -- I had this camera and on the whole I was very satisfied with the results. Only in difficult lighting situations did the AF not always work reliably. So less of a problem for concerts with good lighting but more of a problem for club gigs. I would recommend the Z5 II (not much more expensive), which has a very good and fast AF (accurate in low-light situations) as well as a very good dynamic range. This is particularly advantageous in connection with very bright stage lighting, where the highs can shoot out quickly. Best regards, Enzo Lopardo / enzolopardo.pictures
