Tough to say. I think it really comes down to how critical the extra size / weight is with the 2nd Z8. I personally like having two identical cameras when possible, but I also see a use for the smaller Z6iii at times. Overall though, I would guess the 2nd Z8 is the way to go.Thanks for the great video. Very well done and informative! Has me thinking. I have a z8 which I love and just got a second, which I got in a kit with a z24-120 for a savings. But I like the idea of a lighter backup, though the resolution is a concern. Do I return the second z8 and get the z6iii and lens separately? I did not like the z6ii at all so that is one of my hesitations. Any idea how the battery life is compared to the z8?
