What do you guys think about ergonomics?
I find the function buttons to be quite easy to use, but I've got long fingers, which probably helps.
There's limited flexibility in how you can assign functions to the physical controls, which means that I can't set it up quite the way I want it.
Focus stacking is an ergonomic disaster. It looks like someone at Nikon had read that there was something called focus stacking, and wanted to be able to put it on the feature checklist, but didn't actually know anything about it. Presumably there weren't any smart people left to implement it, so it went to someone on what Michael called "The B Team" in his review of the Fuji X100. It's awful in so many ways, but could easily be fixed in firmware if it ever got assigned to someone on the "A Team".
The virtual horizon is gaudy and intrusive, unlike the nice subtle virtual horizon in Nikon's DSLRs (it looks like the silly version in LiveView got used instead). That's a real shame for me, because I use the virtual horizon in the vast majority of my shots.
Nikon has a reputation for being lazy about firmware updates, but I think that the company is on the line with the Z system, so I'm optimistic that Nikon management will consider allocating some funds to improving the user experience.
