I would be tempted to use a simpler and to compare subject. Maybe something like this focus pattern: https://static.bhphotovideo.com/explora/explora/sites/default/files/bandh-test-target.jpg

For example, the difference between 1/250 and 1/125 of a second is 100%. If there was even a breath of breeze, it could make a difference.

Len,

You're right. This was not a perfectly controlled experiment.

I hadn't noticed it before, but in the first set of pictures, the settings went from 1/125 and ISO 1250 to 1/160 and ISO 1600.

I don't know why. I must have shifted the camera slightly when I turned the IS switch off.

You're right. I should have done this in manual and locked down the exposure.

In picture# 1, I think my focus was on the field between the two trees, and in picture# 2, it was on the tree to the left.

*sigh*
