I get what I think are unusual results using Focus Bracketing on my R5. This may be that I do not understand the menu correctly.
I assumed you set the first focus point to the the closest focus point and then the camera would move to the next calculated distance based on focus length, f-stop and Dof. If you put in 5 exposures it would take five in sequence moving the focus point out each time to slightly overlap the depth of field with the previous exposure.
First, Is this how it works or does anyone have a good explanation of how the algorithm and the menu setting correlate together?
So I had what I thought were unexpected results. This caused me to take a number of test shots on my dining table and from my deck.
Below are the test results from shooting on by dining table. The closest object was 3 feet away and the far wall about 12 feet.
Please note that several times the camera does not take the set number of shots.
I am on the latest firmware.
I get similar results with all lenses.

I also did a number of test shots shooting from my deck. In all cases the last shot or two or always blurry. As if the camera has decided to default to some out of focus position. What is odd about that is the next to last photo is not always at infinity.
