I just picked up a Z50ii, and I'm a big fan of it. I love how easy it is to shoot with one hand. It is just fun to use, and I forgot how awesome it is to use a smaller crop sensor for my walkaround camera. My favorite little camera bag, the Ona Bowery, can take the Z50ii with lens mounted and at least 2 other lenses. I currently have the 16-50 kit lens and 24 1.7 nikon and trying to decide what else to get for it. I think when I'm on the road next month, I'm going to bring the 24-120 f4, 16-50 kit, 24 1.7, 14-30 f4, the Z8 and Z50ii. Perhaps a 50 1.8 S to round out the midrange focal length for primes.
I thought I would miss having an AF joystick on it, but I am finding the directional pad works pretty well as a substitute. The n-log video on it looks great.
I don't care that it doesn't have IBIS myself, as I don't use it for video (I turn it off on my Z8 and Z9 for video), especially considering IBIS would add weight, cost and potentially size to the package. 24 mp would be nice, but in the real world, the difference between a 20 mp and 24 mp file isn't very much, when this is going to be for mostly travel snapshots.
