I'm planning a 2 month (non-photographic-oriented) trip early 2024 to Australia and New Zealand. Weight and compactness with be important and I plan to take only my 24-200mm, 40mm f2, and 14-30mm F4. I have a Z7 (original) and a Zf (with a SmallRig grip). Thoughts on what makes the most sense and why? I don't plan on much wildlife photography, hence nothing real long, although the Z7 will give me a chance to crop more or shoot DX for a little more reach... Mostly landscape, street and travel sights.
I'd say a Z6 II or Z7 II (Z6 II has better low-light and fine if you don't need 45MP), or get a Zf and get improved AF.
Then pair that with a 14-30, a 40 or 50mm for low light, and the 24-200.
You could swap the 24-200 for the 24-120 but you'd have to decide if an extra 80mm and VR but slower apertures is a good compromise over a constant f/4. And that just depends on yourp reference. On one had, the 24-200 starts to lose sharpness around 135mm+ but at the same time, the 24-120 doesn't even go to 135mm so you're not really losing anything (throughout the shared range, the 24-120 and 24-200 are similar, with the 24-120 having the advantage of a constant f/4 aperture and probably being slightly sharper at the longer common focal lengths). Ricci (on Youtube) did a comparison of the 24-120 and 24-200 you could check out. The variable aperture between the shared range is the biggest difference, so with that I'd almost say use the 24-200 for maximum flexibility.
These three lenses should be a good travel kit (you could substitute the 40mm for a smaller/cheaper fast prime). The only downside to the 24-200 is it gets quite slow beyond about 85mm (f/6.3) but it does have VR, which the 24-120 does not.
