Z's do parfocal correction for native focus-by-wire lenses

I see - thanks for the clarification!

So if you were zoomed in, achieved focus, pulled back a bit on the focus, then zoomed back out - the focus would maintain the pulled back state (via lookup table), correct?

I'm not sure if I'm completely understanding your question but the lens does appear to maintain relative focus as you zoom, so if you were OOF at one focal length you'll be OOF at another (and the same naturally is true for when in-focus). It's trickier focusing at 24mm and then going to 70mm because it's harder to get the focus precise enough to still be near-perfect at 70mm (lower optical magnification makes it harder to precisely set focus). But it can be done.

Pleasantly surprised Nikon put that consideration into the Z mount lens.

Agreed, it's an interesting and useful addition.

Yes, that's what I meant - relative focus. Very cool.

I acquired a Nikon AF-P 70-300mm VR DX lens the other day, which is focus-by-wire. It doesn't do the parfocal correction like the native 24-70.

Thank you!

I was thinking about the Sony 28-135, but not quite happy with its still image quality. Now it seemed not necessary to go that route, just stick with the S-line.
