Excellent, congratulations! That's encouraging. So you had no stitching problems, right? Did you need to start each stack in the same plane? Or is the Inspec.x lens telecentric? I suppose the latter, as a machine vision lens.

wow, nice! I was trying to find the 3.5x f/4 version of the lens. Seen a lot of f/5.6 3x one, but I think effective aperture probably kill the sharpness.

one suggestion, not sure if you know this, you can try www.easyzoom.com

Lou, It worked on the first try, I just specify near-far points for stacking then batch processed in HF and stitched in PTgui. I did not check for telecentricity, but like you said it might be.
