Hi Georg! You're almost right: most of my lenses are primes (and Manuals!), but I have the M 75-150mm too. The Meyer-Görlitz is one of my favourites: 15 aperture blades, very smooth bokeh and at f/2 a a fantastic DOF. So, if there is a possibility to lay your hands on one, you should buy it imo. There are weeks in which this lens is on my body continuously...
