Please bear with me a moment

Most of my shooting now is tripod close-up/macro utilizing my 180 macro mounted on a dated 1Ds3.
I also use Canon Utility Software tethered to my computer using the LV function with the automatic
focus changes with the arrow gizmos which I then use to stack images using PS CC.

Being an anal retentive SOB...are there any of the newer cameras that will cough out better IQ?

looks like its doing what you want, personally I loved my 1DIII (never had the 1DsIII) and kind of wish I had not sold it

Think I would look at trying some different stacking software first such as zerene stacker. Potentially might have a bigger impact on IQ than a new body.

The quality of the light that your using will also have a big impact on the level of detail that you capture, even if you're not focus stacking.
