Back in the late 1980s my wife asked me what all those noises that came from a modem at the beginning of an on-line session were. I told her that the modem on her desk was negotiating with the modem at the other end to find out what each was capable of, so that they could communicate for the rest of the session with the most advanced protocol that they shared in common.
She said, “That’s what you do when you first meet someone at a party, isn’t it?”
I hadn’t thought about it that way, but I had to admit that she was right.
It doesn’t work so well on the Internet.

Hi Jim, thanks for coming back.
Well, it is nothing new. the (in)cosistant between lens and body is very important. If you put a lens, which have less resolution, as the digicam body has, then your image will be blurred!
The second point is the image stabilization. You write enough test on your blog.
IMO higher speed give not less blur on the image. Because the electronic speed of the sensor transistor is always the same!!!
You have to find out, wich shutter speed is in good combination with the electronic speed of the sensor. Here is a good video about that: https://www.youtube.com/watch?v=CmjeCchGRQo
And it depens on every manufacturer system!

From my tests, it’s simpler than that. You have to find out when you don’t need the IBIS, and turn it off for that shutter speed and faster. Usually it’s around 1/(5*FL). With IBIS off, higher shutter speed is always less blur. I’m assuming no optical stabilization in the lens.
