Literally the ONLY flaw on a Z9

When you speak of edge acuity, what exactly does this mean?

The simplest way to think about this is that a line in the scene is distinctly a line in the resulting image with a clear edge. What happens with VR, diffraction, and a host of other scenarios is that the line becomes less edgy and more of a transition.

Thanks Thom. Even with my pixel peeping I've never noticed this. Now I'll have to start looking for it. I sure hope I don't find it because it'll probably drive me nuts if I do.

I'm going to assume this only happens at very slow shutter speeds, when the VR is actually helping.

I believe the answer to that is "no". That's why the recommendation to turn it off over a certain shutter speed.

That makes sense. I tend to leave it on at times I really don't need it except that it stabilizes the image when tracking moving subjects.

That's the tradeoff. Better composition and maybe AF, versus getting some "fuzz" on your edges and artifacts in your bokeh.

I forget (because I don't use it), but isn't there a configuration you can use that only activates VR (and maybe IBIS as well) when you press the shutter button? My vague recollection says something about setting AF-ON to not activate VR but setting VR to activate only on the shutter button. Yes/No?

If I recall this correctly, would it be practical or have any advantage if VR was activated during the pre-release process of framing and tracking your subject but turned off for the actual capture?

I was the guy who said that I didn't see anything jumping on my Z8. That was true with a short lens. But I went out today with a telephoto and, sure enough, there was that little jump that people have been complaining about as the IBIS re-centers.

But I also had my tripod with me. And guess what? With the camera on the tripod, there was no jump whatsoever.

So that proves, to my satisfaction at least, that the jump is an issue with hand holding, not something that can be fixed in firmware (at least not it we want IBIS to continue to work optimally).

I know some people don't like this, but I don't think it's something that Nikon would consider a flaw and look to fix as it's been the way their VR systems have worked basically since they first started producing them. In fact, it's to a significant degree the reason that Sports mode exists at all: Sports mode is basically different from normal mode in that Sports mode doesn't have this behavior.

Yep I get this. Fortunately my typical use much of the time is if I'm birding I'm shooting at 8fps and never see it happen under those circumstances. Also if on a tripod doing a landscape I incorporate the exposure delay and hit the shutter and don't watch it happen so never see it as well. So I guess I'll just forget about it and move on. Like I said it's no deal breaker.

It may just be a matter of semantics, but once again, it has nothing to do with the camera's IBIS, "In Body Image Stability". It's a function the VR system in the lens.

But if you're using a tele on a tripod with VR turned on, slowly move the camera around and watch the image float around. It can make accurate framing a problem until it settles down. Kinda like looking out the port of a boat at sea.

You should be in sport mode when shooting BIF and turn VR off or leave in sport mode when on a tripod.
