Quite interesting trend for myself to observe and help me understand if I am missing something...Z8 is around 910g while Z9 is around 1340g.
Obviously Z8 is lighter than Z9 and many people chose it just because of this. But Many Z8 users are now putting big cages around Z8 to avoid anchor issues and so one. The cage itself is weight around 200-300g. Considering Z8 needs more batteries, so people are carrying around 2 more batteries, each around 100g.
So after all we are again going back to the weight of Z9 without additional benefits. Of course handheld Z8 is lighter still than Z9, but if I think the weight in my backpack, it is kind of the same specially if you plan to add power bank also instead of extra batteries.
I certainly wouldn’t say “many users”. The internet and forums are a cesspool of confirmation bias. You don’t hear from the so-called “silent majority” who don’t have problems. We know that the 1st batch of Z8s sold out rapidly - all 12,000 of them. We also know that the 2nd batch sold out rapidly. Let’s assume that’s another 12,000.
We’ve seen - at least on DPReview - a grand total of 2 issues w.r.t. anchor posts.
Well, there is no way that we know what majority thinks, but checking online here and facebook, seems everyone is buying now a cage and others recommend it. I personally cannot trust having Z8 now and attach strap to my anchor points until enough time and we make sure people are really have no issue.
Similarly, there’s very little chance that a majority, or even a significant minority of Z8 owners will have bought cages to deal with anchor issues. Rather, those who have bought them would have done so for other reasons - like mounting accessories for video usage, for example - and would have done the same with a Z9.
As to batteries - when I take my Z9 with me, I take a spare battery. That weight is at least double the weight of a single EN-EL15c. If I’m going to need a power bank for the Z8, then I’m also going to need one for the Z9 - that’s pretty much a fairly extreme edge case.
I believe you are confusing what I said. Of course you can still choose to have extra battery for Z9. But if you think about it, Z8 battery is equal to 2.3 * Z8 batteries = 1 Z9 battery.. now do calculation and see how much weight is increased.
EN-EL18d is 160 g -> 36Wh
EN-EL15C is 100g -> 16 Wh (almost equal to 40% less power than EN-EL18D)
you need more than two Z8 battery to be almost equal Z9 battery.
