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*

Hi Steve, I am affraid you are comparing apples to oranges. Testing on a grass in breeze and speaking about Christmas pics with your shy better half…

If you want to test the IS (side) effects, use the wall clock face instead.

IS on or off on tripod nowadays doesn’t matter, but what’s the goal, how we could help?
Friendly, guinness
