Try it and see. It will give you something to do while waiting for an answer from someone who has seen it.

Some lenses when turned off do a total retraction and then when turned on go to a default position. Especially zooms. It is more common in fixed lens cameras but some interchangable zooms also do it. It may be zooming or it may be the AF, it depends on the lens.

Had a camera that did that. There was an item in the menus called “pre focus” that I turned off. Viola!

I use Minolta AF lenses on my Sony A7+ bodies. All of them do a short dance when I turn on the camera. I've always just assumed it is the autofocus calibrating/resetting...
